camp." "Let one of us accompany you, Mr. Dick." "No, Tom, I shall go alone. I can approach without being seen. Stay here." The little troop, that followed Tom and Dick Sand, halted. The young novice left at once and disappeared in the darkness, which was profound when the lightning did not tear the sky. Some large drops of rain already began to fall. "What is the matter?" asked Mrs. Weldon, approaching the old black. "We have perceived a camp, Mrs. Weldon," replied Tom; "a camp--or, perhaps, a village, and our captain wished to reconnoiter it before leading us to it." Mrs. Weldon was satisfied with this reply. Three minutes after, Dick Sand was returning. "Come! come!" he cried, in a voice which expressed his entire satisfaction. "The camp is abandoned?" asked Tom. "It is not a camp," replied the young novice; "it is not a village. They are ant-hills!" "Ant-hills!" exclaimed Cousin Benedict, whom that word aroused. "Yes, Mr. Benedict, but ant-hills twelve feet high, at least, and in which we shall endeavor to hide ourselves." "But then," replied Cousin Benedict, "those would be ant-hills of the warlike termite or of the devouring termite. Only those ingenious insects raise such monuments, which the greatest architects would not disown." "Whether they be termites or not, Mr. Benedict," replied Dick Sand, "we must dislodge them and take their place." "They will devour us. They will be defending their rights." "Forward! Forward!" "But, wait now!" said Cousin Benedict again. "I thought those ant-hills only existed in Africa." "Forward!" exclaimed Dick Sand, for the last time, with a sort of violence. He was so much afraid that Mrs. Weldon might hear the last word pronounced by the entomologist. They followed Dick Sand with all haste. A furious wind had sprung up. Large drops crackled on the ground. In a few moments the squalls of wind would become unbearable. Soon one of those cones which stood on the plain was reached. No matter how threatening the termites might be, the human beings must not hesitate. If they could not drive the insects away, they must share their abode. At the bottom of this cone, made with a kind of reddish clay, there was a very narrow hole. Hercules enlarged it with his cutlass in a few moments, so as to give a passage even to a man like himself. To Cousin Benedict's extreme surprise, not one of the thousands of termites that ought to occupy the ant-hill showed itself. Was, then, the cone abandoned? The hole enlarged, Dick and his companions glided into it. Hercules disappeared the last, just as the rain fell with such rage that it seemed to extinguish the lightnings. But those wind squalls were no longer to be feared. A happy chance had furnished this little troop with a solid shelter, better than a tent, better than a native's hut. It was one of those termite cones that, according to Lieutenant Cameron's comparison, are more astonishing than the pyramids of Egypt, raised by the hands of men, because they have been built by such small insects. "It is," said he, "as if a nation had built Mount Everest, the highest mountain of the Himalaya chain." CHAPTER V. ANTS AND THEIR DWELLING. At this moment the storm burst with a violence unknown in temperate latitudes. It was providential that Dick Sand and his companions had found this refuge! In fact, the rain did not fall in distinct drops, but in streams of various thickness. Sometimes it was a compact mass forming a sheet of water, like a cataract, a Niagara. Imagine an aerial basin, containing a whole sea, being upset. Under such showers the ground was hollowed out, the plains were changed to lakes, the streams to torrents, the rivers, overflowing, inundated vast territories. In temperate zones the violence of the storms decreases according to their duration; but in Africa, however heavy they are, they continue for several entire days. How can so much electricity be collected in the clouds? How can such quantities of vapor be accumulated? It is very difficult to comprehend this. However, such are the facts, and one might suppose himself transported to the extraordinary epochs of the diluvian period. Fortunately, the ant-cone, with its thick walls, was perfectly impervious. A beaver's hut, of well-beaten earth, could not have been more water-tight. A torrent could have passed over it without a single drop of water filtering through its pores. As soon as Dick Sand and his companions had taken possession of the cone they occupied themselves in examining its interior arrangement. The lantern was lighted, and the ant-hill was sufficiently illuminated. This cone, which measured twelve feet in height inside, was eleven feet wide, except in its upper part, which rounded in the form of a sugar loaf. Everywhere the walls were about one foot in thickness, and there was a distance between the stories of cells which adorned them. We may be astonished at the construction of such monuments, due to these industrious swarms of insects, but it is true that they are frequently found in the interior of Africa. Smeathman, a Dutch traveler of the last century, with four of his companions, occupied the top of one of these cones. In the Lounde, Livingstone observed several of these ant-hills, built of reddish clay, and attaining a height of fifteen and twenty feet. Lieutenant Cameron has many a time mistaken for a camp these collections of cones which dotted the plain in N'yangwe. He has even stopped at the foot of great edifices, not more than twenty feet high, but composed of forty or fifty enormous rounded cones, flanked with bell-towers like the dome of a cathedral, such as Southern Africa possesses. To what species of ant was due, then, the prodigious style of architecture of these cones? "To the warlike termite," Cousin Benedict had replied, without hesitating, as soon as he had recognized the nature of the materials employed in their construction. And, in fact, the walls, as has been said, were made of reddish clay. Had they been formed of a gray or black alluvian earth, they must have been attributed to the "termes mordax" or the "termes atrox." As we see, these insects have not very cheering names--a fact which cannot but please a strong entomologist, such as Cousin Benedict. The central part of the cone, in which the little troop had first found shelter, and which formed the empty interior, would not have contained them; but large cavities, in close contact, made a number of divisions, in which a person of medium height could find refuge. Imagine a succession of open drawers, and at the bottom of those drawers millions of cells which the termites had occupied, and the interior disposition of the ant-hill is easily understood. To sum up, these drawers are in tiers, like the berths in a ship's cabin. In the upper ones Mrs. Weldon, little Jack, Nan, and Cousin Benedict took refuge. In the lower row Austin, Bat, and Acteon hid themselves. As for Dick Sand, Tom, and Hercules, they remained in the lower part of the cone. "My friends," then said the young novice to the two blacks, "the ground is becoming damp. We must fill it up by crumbling the red clay from the base; but take care not to obstruct the hole by which the air enters. We cannot risk being smothered in this ant-hill." "We have only one night to spend here," replied old Tom. "Well, let us try and make it recover us from our fatigue. This is the first time in ten days that we have not to sleep in the open air." "Ten days!" repeated Tom. "Besides," added Dick Sand, "as this cone forms a solid shelter, perhaps we had better stay here twenty-four hours. During that time, I will go in search of the stream that we are in need of; it cannot be very distant. I think that until we have constructed our raft, it will be better not to quit this shelter. The storm cannot reach us here. Let us make the floor stronger and dryer." Dick Sand's orders were executed at once. Hercules, with his ax, crumbled the first story of cells, which was composed of crisp red clay. He thus raised, more than a foot, the interior part of the swampy earth on which the ant-hill rested, and Dick Sand made sure that the air could freely penetrate to the interior of the cone through the orifice pierced at its base. It was, certainly, a fortunate circumstance that the ant-hill had been abandoned by the termites. With a few thousands of these ants, it would have been uninhabitable. But, had it been evacuated for some time, or had the voracious newroptera but just quitted it? It was not superfluous to ponder this question. Cousin Benedict was so much surprised at the abandonment, that he at once considered the reason for it, and he was soon convinced that the emigration had been recent. In fact, he did not wait, but, descending to the lower part of the cone, and taking the lantern, he commenced to examine the most secret corners of the ant-hill. He thus discovered what is called the "general store-house" of the termites, that is to say, the place where these industrious insects lay up the provisions of the colony. It was a cavity hollowed in the wall, not far from the royal cell, which Hercules's labor had destroyed, along with the cells destined for the young larvae. In this store-room Cousin Benedict collected a certain quantity of particles of gum and the juices of plants, scarcely solidified, which proved that the termites had lately brought them from without. "Well, no!" cried he. "No!" as if he were replying to some contradiction, "No, this ant-hill has not been long abandoned." "Who says to the contrary, Mr. Benedict?" said Dick Sand. "Recently or not, the important thing for us is that the termites have left it, because we have to take their place." "The important thing," replied Cousin Benedict, "will be to know why they have left it. Yesterday--this morning, perhaps--these sagacious newroptera were still here, because, see these liquid juices; and this evening----" "Well, what do you conclude, Mr. Benedict?" asked Dick Sand. "That a secret presentiment has caused them to abandon the cone. Not only have all the termites left their cells, but they have taken care to carry away the young larvae, of which I cannot find one. Well, I repeat that all this was not done without a motive, and that these sagacious insects foresaw some near danger." "They foresaw that we were going to invade their dwelling," replied Hercules, laughing. "Indeed!" replied Cousin Benedict, whom this answer sensibly shocked. "You think yourself so strong that you would be dangerous to these courageous insects? A few thousand of these newroptera would quickly reduce you to a skeleton if they found you dead on the road." "Dead, certainly," replied Hercules, who would not give up; "but, living, I could crush masses of them." "You might crush a hundred thousand, five hundred thousand, a million," replied Cousin Benedict, with animation, "but not a thousand millions; and a thousand millions would devour you, living or dead, to the last morsel." During this discussion, which was less trifling than might be supposed, Dick Sand reflected on the observations made by Cousin Benedict. There was no doubt that the savant knew too much about the habits of the termites to be mistaken. If he declared that a secret instinct warned them to leave the ant-hill recently, it was because there was truly peril in remaining in it. Meanwhile, as it was impossible to abandon this shelter at a moment when the storm was raging with unparalleled intensity, Dick Sand looked no farther for an explanation of what seemed to be inexplicable, and he contented himself with saying: "Well, Mr. Benedict, if the termites have left their provisions in this ant-hill, we must not forget that we have brought ours, and let us have supper. To-morrow, when the storm will be over, we will consult together on our future plans." They then occupied themselves in preparing the evening meal, for, great as their fatigue was, it had not affected the appetite of these vigorous walkers. On the contrary, the food, which had to last for two more days, was very welcome. The damp had not reached the biscuits, and for several minutes it could be heard cracking under the solid teeth of Dick Sand and his companions. Between Hercules's jaws it was like grain under the miller's grindstone. It did not crackle, it powdered. Mrs. Weldon alone scarcely eat, and even Dick Sand's entreaties were vain. It seemed to him that this brave woman was more preoccupied, more sad than she had been hitherto. Meanwhile her little Jack suffered less; the fever had not returned, and at this time he was sleeping, under his mother's eyes, in a cell well lined with garments. Dick Sand knew not what to think. It is useless to say that Cousin Benedict did honor to the repast, not that he paid any attention either to the quality or to the quantity of the food that he devoured, but because he had found an opportunity to deliver a lecture in entomology on the termites. Ah! if he had been able to find a termite, a single one, in the deserted ant hill! But nothing. "These admirable insects," said he, without taking the trouble to find out if any one were listening--"these admirable insects belong to the marvelous order of newroptera, whose horns are longer than the head, the jaws very distinct, and whose lower wings are generally equal to the upper ones. Five tribes constitute this order: the Panorpates (scorpion flies), the Myrmileoniens, the Hemerobins, the Termitines and the Perlides. It is useless to add that the insects which now interest us, and whose dwelling we occupy, perhaps unduly, are the Termitines." At this moment Dick Sand listened very attentively to Cousin Benedict. Had the meeting with these termites excited in him the thought that he was perhaps on the African continent, without knowing by what chance he had arrived there? The young novice was very anxious to find out. The savant, mounted on his favorite hobby, continued to ride it beautifully. "Now these termitines," said he, "are characterized by four joints on the instep, horned jaws, and remarkable strength. We have the -mantispe- species, the -raphidie-, and the termite species. The last is often known under the term of white ants, in which we count the deadly termite, the yellow corslet termite, the termite that shuns the light, the biter, the destroyer--" "And those that constructed this ant-hill?" asked Dick Sand. "They are the martial ants," replied Cousin Benedict, who pronounced this word as if it had been the Macedonians, or some other ancient people brave in war. "Yes, the warlike ants, and of all sizes. Between Hercules and a dwarf the difference would be less than between the largest of these insects and the smallest. Among them are 'workers' of five millimeters in length 'soldiers' of ten, and males and females of twenty. We find also a kind otherwise very curious: the -sirafous- half an inch in length, which have pincers for jaws, and a head larger than the body, like the sharks. They are the sharks among insects, and in a fight between some -sirafous- and a shark, I would bet on the -sirafous-." "And where are these -sirafous- commonly observed?" then asked Dick Sand. "In Africa," replied Cousin Benedict; "in the central and southern provinces. Africa is, in fact, the country of ants. You should read what Livingstone says of them in the last notes reported by Stanley. More fortunate than myself, the doctor has witnessed a Homeric battle, joined between an army of black ants and an army of red ants. The latter, which are called 'drivers,' and which the natives name -sirafous-, were victorious. "The others, the '-tchoungous-,' took flight, carrying their eggs and their young, not without having bravely defended themselves. Never, according to Livingstone, never was the spirit of battle carried farther, either among men or beasts! With their tenacious jaws, which tear out the piece, these -sirafous- make the bravest man recoil. The largest animals--even lions and elephants--flee before them. "Nothing stops them; neither trees, which they climb to the summit, nor streams, which they cross by making a suspension bridge of their own bodies, hooked together. And numerous! Another African traveler--Du Chaillu--has seen a column of these ants defile past him for twelve hours without stopping on the road. But why be astonished at the sight of such myriads? The fecundity of these insects is surprising; and, to return to our fighting termites, it has been proved that a female deposits as much as sixty thousand eggs in a day! Besides, these newroptera furnish the natives with a juicy food. Broiled ants, my friends; I know of nothing better in the world!" "Have you then eaten them, Mr. Benedict?" asked Hercules. "Never," replied the wise professor; "but I shall eat some." "Where?" "Here." "Here; we are not in Africa!" said Tom, very quickly. "No, no!" replied Cousin Benedict; "and, thus far, these warlike termites, and their villages of ant-hills, have only been observed on the African Continent. Ah! such travelers. They do not know how to see! Well! all the better, after all. I have discovered a -tsetse- in America. To the glory of this, I shall join that of having found the warlike termites on the same continent! What matter for an article that will make a sensation in educated Europe, and, perhaps, appear in folio form, with prints and engravings, besides the text!" It was evident that the truth had not entered Cousin Benedict's brain. The poor man and all his companions, Dick Sand and Tom excepted, believed themselves, and must believe themselves, where they were not! It needed other incidents, facts still more grave than certain scientific curiosities, to undeceive them! It was then nine o'clock in the morning. Cousin Benedict had talked for a long time. Did he perceive that his auditors, propped up in their cells, had gradually fallen asleep during his entomological lecture? No; certainly not. He lectured for himself. Dick Sand no longer questioned him, and remained motionless, although he did not sleep. As for Hercules, he had resisted longer than the others; but fatigue soon finished by shutting his eyes, and, with his eyes, his ears. For some time longer Cousin Benedict continued to lecture. However, sleep finally got the best of him, and he mounted to the upper cavity of the cone, in which he had chosen his domicile. Deep silence fell on the interior of the cone, while the storm filled space with noise and fire. Nothing seemed to indicate that the tempest was nearly over. The lantern had been extinguished. The interior of the ant-hill was plunged in complete darkness. No doubt all slept. However, Dick Sand, alone, did not seek in sleep the repose which was so necessary to him. Thought absorbed him. He dreamed of his companions, whom he would save at all hazards. The wrecking of the "Pilgrim" had not been the end of their cruel trials, and others, still more terrible, threatened them should they fall into the hands of these natives. And how to avoid this danger, the worst of all, during their return to the coast. Harris and Negoro had not led them a hundred miles into the interior of Angola without a secret design to gain possession of them. But what did this miserable Portuguese intend? Who had merited his hatred? The young novice repeated to himself, that he alone had incurred it. Then he passed in review all the incidents that had taken place during the "Pilgrim's" voyage; the meeting with the wreck and the blacks; the pursuit of the whale; the disappearance of Captain Hull and his crew. Dick Sand had found himself, at the age of fifteen, intrusted with the command of a vessel, the compass and log of which were soon injured by Negoro's criminal actions. He again saw himself using his authority in the presence of this insolent cook, threatening to put him in irons, or to blow out his brains with a pistol shot. Ah, why had he hesitated to do it? Negoro's corpse would have been thrown overboard, and none of these catastrophes would have happened. Such were the young man's various thoughts. Then they dwelt a moment on the shipwreck which had ended the "Pilgrim's" voyage. The traitor Harris appeared then, and this province of South America gradually became transformed. Bolivia changed to the terrible Angola, with its feverish climate, its savage deer, its natives still more cruel. Could the little party escape during its return to the coast? This river which he was seeking, which he hoped to find, would it conduct them to the shore with more safety, and with less fatigue? He would not doubt it, for he knew well that a march of a hundred miles through this inhospitable country, in the midst of incessant dangers, was no longer possible. "Happily," he said to himself, "Mrs. Weldon and all are ignorant of the danger of the situation. Old Tom and I, we alone are to know that Negoro has thrown us on the coast of Africa; and that Harris has led me into the wilds of Angola." Dick Sand was thus sunk in overpowering thoughts, when he felt a breath on his forehead. A hand rested on his shoulder, and a trembling voice murmured these words in his ear: "I know all, my poor Dick, but God can yet save us! His will be done!" CHAPTER VI. THE DIVING-BELL. To this unexpected revelation Dick Sand could not reply. Besides, Mrs. Weldon had gone back at once to her place beside little Jack. She evidently did not wish to say any more about it, and the young novice had not the courage to detain her. Thus Mrs. Weldon knew what to believe. The various incidents, of the way had enlightened her also, and perhaps, too, that word, "Africa!" so unluckily pronounced the night before by Cousin Benedict. "Mrs. Weldon knows everything," repeated Dick Sand to himself. "Well, perhaps it is better so. The brave woman does not despair. I shall not despair either." Dick Sand now longed for day to return, that he might explore the surroundings of this termite village. He must find a tributary of the Atlantic with a rapid course to transport all his little troop. He had a presentiment that this watercourse could not be far distant. Above all, they must avoid an encounter with the natives, perhaps already sent in pursuit of them under Harris's and Negoro's direction. But it was not day yet. No light made its way into the cone through the lower orifice. Rumblings, rendered low by the thickness of the walls, indicated that the storm still raged. Listening, Dick Sand also heard the rain falling with violence at the base of the ant-hill. As the large drops no longer struck a hard soil, he must conclude that the whole plain was inundated. It must have been about eleven o'clock. Dick Sand then felt that a kind of torpor, if not a true sleep, was going to overcome him. It would, however, be rest. But, just as he was yielding to it, the thought came to him that, by the settling of the clay, washed in, the lower orifice was likely to be obstructed. All passage for the outer air would be closed. Within, the respiration of ten persons would soon vitiate the air by loading it with carbonic acid. Dick Sand then slipped to the ground, which had been raised by the clay from the first floor of cells. That cushion was still perfectly dry, and the orifice entirely free. The air penetrated freely to the interior of the cone, and with it some flashes of lightning, and the loud noises of that storm, that a diluvian rain could not extinguish. Dick Sand saw that all was well. No immediate danger seemed to menace these human termites, substituted for the colony of newroptera. The young novice then thought of refreshing himself by a few hours' sleep, as he already felt its influence. Only with supreme precaution Dick Sand lay on that bed of clay, at the bottom of the cone, near the narrow edifice. By this means, if any accident happened outside, he would be the first to remark it. The rising day would also awaken him, and he would be ready to begin the exploration of the plain. Dick Sand lay down then, his head against the wall, his gun under his hand, and almost immediately he was asleep. How long this drowsiness lasted he could not tell, when he was awakened by a lively sensation of coolness. He rose and recognized, not without great anxiety, that the water was invading the ant hill, and even so rapidly, that in a few seconds it would reach the story of cells occupied by Tom and Hercules. The latter, awakened by Dick Sand, were told about this new complication. The lighted lantern soon showed the interior of the cone. The water had stopped at a height of about five feet, and remained stationary. "What is the matter, Dick?" asked Mrs. Weldon. "It is nothing," replied the young novice. "The lower part of the cone has been inundated. It is probably that during this storm a neighboring river has overflowed on this plain." "Good!" said Hercules; "that proves the river is there!" "Yes," replied Dick Sand, "and it will carry us to the coast. Be reassured, then, Mrs. Weldon; the water cannot reach you, nor little Jack, nor Nan, nor Mr. Benedict." Mrs. Weldon did not reply. As to the cousin, he slept like a veritable termite. Meanwhile the blacks, leaning over this sheet of water, which reflected the lantern's light, waited for Dick Sand to indicate to them what should be done. He was measuring the height of the inundation. After having the provisions and arms put out of the reach of the inundation, Dick Sand was silent. "The water has penetrated by the orifice," said Tom. "Yes," replied Dick Sand, "and now it prevents the interior air from being renewed." "Could we not make a hole in the wall above the level of the water?" asked the old black. "Doubtless, Tom; but if we have five feet of water within, there are perhaps six or seven, even more, without." "You think, Mr. Dick--?" "I think, Tom, that the water, rising inside the ant-hill, has compressed the air in the upper part, and that this air now makes an obstacle to prevent the water from rising higher. But if we pierce a hole in the wall by which the air would escape, either the water would still rise till it reached the outside level, or if it passed the hole, it would rise to that point where the compressed air would again keep it back. We must be here like workmen in a diving-bell." "What must be done?" asked Tom. "Reflect well before acting," replied Dick Sand. "An imprudence might cost us our lives!" The young novice's observation was very true. In comparing the cone to a submerged bell, he was right. Only in that apparatus the air is constantly renewed by means of pumps. The divers breathe comfortably, and they suffer no other inconveniences than those resulting from a prolonged sojourn in a compressed atmosphere, no longer at a normal pressure. But here, beside those inconveniences, space was already reduced a third by the invasion of the water. As to the air, it would only be renewed if they put it in communication with the outer atmosphere by means of a hole. Could they, without running the danger spoken of by Dick Sand, pierce that hole? Would not the situation be aggravated by it? What was certain was, that the water now rested at a level which only two causes could make it exceed, namely: if they pierced a hole, and the level of the rising waters was higher outside, or if the height of this rising water should still increase. In either of these cases, only a narrow space would remain inside the cone, where the air, not renewed, would be still more compressed. But might not the ant-hill be torn from the ground and overthrown by the inundation, to the extreme danger of those within it? No, no more than a beaver's hut, so firmly did it adhere by its base. Then, the event most to be feared was the persistence of the storm, and, consequently, the increase of the inundation. Thirty feet of water on the plain would cover the cone with eighteen feet of water, and bear on the air within with the pressure of an atmosphere. Now, after reflecting well upon it, Dick Sand was led to fear that this inundation might increase considerably. In fact, it could not be due solely to that deluge poured out by the clouds. It seemed more probable that a neighboring watercourse, swelled by the storm, had burst its banks, and was spreading over this plain lying below it. What proof had they that the ant-hill was not then entirely submerged, and that it was full time to leave it by the top part, which would not be difficult to demolish? Dick Sand, now extremely anxious, asked himself what he ought to do. Must he wait or suddenly announce the probable result of the situation, after ascertaining the condition of things? It was then three o'clock in the morning. All, motionless, silent, listened. The noise from outside came very feebly through the obstructed orifice. All the time a dull sound, strong and continued, well indicated that the contest of the elements had not ceased. At that moment old Tom observed that the water level was gradually rising. "Yes," replied Dick Sand, "and if it rises, as the air cannot escape from within, it is because the rising of the waters increases and presses it more and more." "It is but slight so far," said Tom. "Without doubt," replied Dick Sand; "but where will this level stop?" "Mr. Dick," asked Bat, "would you like me to go out of the ant-hill? By diving, I should try to slip out by the hole." "It will be better for me to try it," replied Dick Sand. "No, Mr. Dick, no," replied old Tom, quickly; "let my son do it, and trust to his skill. In case he could not return, your presence is necessary here." Then, lower: "Do not forget Mrs. Weldon and little Jack." "Be it so," replied Dick Sand. "Go, then, Bat. If the ant-hill is submerged, do not seek to enter it again. We shall try to come out as you will have done. But if the cone still emerges, strike on its top with the ax that you will take with you. We will hear you, and it will be the signal for us to demolish the top from our side. You understand?" "Yes, Mr. Dick," replied Bat. "Go, then, boy," added old Tom, pressing his son's hand. Bat, after laying in a good provision of air by a long aspiration, plunged under the liquid mass, whose depth then exceeded five feet. It was a rather difficult task, because he would have to seek the lower orifice, slip through it, and then rise to the outside surface of the waters. That must be done quickly. Nearly half a minute passed away. Dick Sand then thought that Bat had succeeded in passing outside when the black emerged. "Well!" exclaimed Dick Sand. "The hole is stopped up by rubbish!" replied Bat, as soon as he could take breath. "Stopped up!" repeated Tom. "Yes," replied Bat. "The water has probably diluted the clay. I have felt around the walls with my hand. There is no longer any hole." Dick Sand shook his head. His companions and he were hermetically sequestered in this cone, perhaps submerged by the water. "If there is no longer any hole," then said Hercules, "we must make one." "Wait," replied the young novice, stopping Hercules, who, hatchet in hand, was preparing to dive. Dick Sand reflected for a few moments, and then he said: "We are going to proceed in another manner. The whole question is to know whether the water covers the ant-hill or not. If we make a small opening at the summit of the cone, we shall find out which it is. But in case the ant-hill should be submerged now, the water would fill it entirely, and we would be lost. Let us feel our way." "But quickly," replied Tom. In fact, the level continued to rise gradually. There were then six feet of water inside the cone. With the exception of Mrs. Weldon, her son, Cousin Benedict, and Nan, who had taken refuge in the upper cavities, all were immersed to the waist. Then there was a necessity for quick action, as Dick Sand proposed. It was one foot above the interior level, consequently seven feet from the ground, that Dick Sand resolved to pierce a hole in the clay wall. If, by this hole, they were in communication with the outer air, the cone emerges. If, on the contrary, this hole was pierced below the water level outside, the air would be driven inward, and in that case they must stop it up at once, or the water would rise to its orifice. Then they would commence again a foot higher, and so on. If, at last, at the top, they did not yet find the outer air, it was because there was a depth of more than fifteen feet of water in the plain, and that the whole termite village had disappeared under the inundation. Then what chance had the prisoners in the ant-hill to escape the most terrible of deaths, death by slow asphyxia? Dick Sand knew all that, but he did not lose his presence of mind for a moment. He had closely calculated the consequences of the experiment he wished to try. Besides, to wait longer was not possible. Asphyxia was threatening in this narrow space, reduced every moment, in a medium already saturated with carbonic acid. The best tool Dick Sand could employ to pierce a hole through the wall was a ramrod furnished with a screw, intended to draw the wadding from a gun. By making it turn rapidly, this screw scooped out the clay like an auger, and the hole was made little by little. Then it would not have a larger diameter than that of the ramrod, but that would be sufficient. The air could come through very well. Hercules holding up the lantern lighted Dick Sand. They had some wax candles to take its place, and they had not to fear lack of light from that source. A minute after the beginning of the operation, the ramrod went freely through the wall. At once a rather dull noise was produced, resembling that made by globules of air escaping through a column of water. The air escaped, and, at the same moment, the level of the water rose in the cone, and stopped at the height of the hole. This proved that they had pierced too low--that is to say, below the liquid mass. "Begin again," the young novice said, coolly, after rapidly stopping the hole with a handful of clay. The water was again stationary in the cone, but the reserved space had diminished more than eight inches. Respiration became difficult, for the oxygen was beginning to fail. They saw it also by the lantern's light, which reddened and lost a part of its brightness. One foot above the first hole, Dick Sand began at once to pierce a second by the same process. If the experiment failed, the water would rise still higher inside the cone--but that risk must be run. While Dick Sand was working his auger, they heard Cousin Benedict cry out, suddenly: "Mercy! look--look--look why!" Hercules raised his lantern and threw its light on Cousin Benedict, whose face expressed the most perfect satisfaction. "Yes," repeated he, "look why those intelligent termites have abandoned the ant-hill! They had felt the inundation beforehand. Ah! instinct, my friends, instinct. The termites are wiser than we are, much wiser." And that was all the moral Cousin Benedict drew from the situation. At that moment Dick Sand drew out the ramrod, which had penetrated the wall. A hissing was produced. The water rose another foot inside the cone--the hole had not reached the open air outside. The situation was dreadful. Mrs. Weldon, then almost reached by the water, had raised little Jack in her arms. All were stifling in this narrow space. Their ears buzzed. The lantern only threw a faint light. "Is the cone, then, entirely under water?" murmured Dick Sand. He must know; and, in order to know, he must pierce a third hole, at the very top. But it was asphyxia, it was immediate death, if the result of this last attempt should prove fruitless. The air remaining inside would escape through the upper sheet of water, and the water would fill the whole cone. "Mrs. Weldon," then said Dick Sand, "you know the situation. If we delay, respirable air will fail us. If the third attempt fails, water will fill all this space. Our only chance is that the summit of the cone is above the level of the inundation. We must try this last experiment. Are you willing?" "Do it, Dick!" replied Mrs. Weldon. At that moment the lantern went out in that medium already unfit for combustion. Mrs. Weldon and her companions were plunged in the most complete darkness. Dick Sand was perched on Hercules's shoulders. The latter was hanging on to one of the lateral cavities. Only his head was above the bed of water. Mrs. Weldon, Jack, and Cousin Benedict were in the last story of cells. Dick Sand scratched the wall, and his ramrod pierced the clay rapidly. In this place the wall, being thicker and harder also, was more difficult to penetrate. Dick Sand hastened, not without terrible anxiety, for by this narrow opening either life was going to penetrate with the air, or with the water it was death. Suddenly a sharp hissing was heard. The compressed air escaped--but a ray of daylight filtered through the wall. The water only rose eight inches, and stopped, without Dick Sand being obliged to close the hole. The equilibrium was established between the level within and that outside. The summit of the cone emerged. Mrs. Weldon and her companions were saved. At once, after a frantic hurra, in which Hercules's thundering voice prevailed, the cutlasses were put to work. The summit, quickly attacked, gradually crumbled. The hole was enlarged, the pure air entered in waves, and with it the first rays of the rising sun. The top once taken off the cone, it would be easy to hoist themselves on to its wall, and they would devise means of reaching some neighboring height, above all inundations. Dick Sand first mounted to the summit of the cone. A cry escaped him. That particular noise, too well known by African travelers, the whizzing of arrows, passed through the air. Dick Sand had had time to perceive a camp a hundred feet from the ant-hill, and ten feet from the cone, on the inundated plain, long boats, filled with natives. It was from one of those boats that the flight of arrows had come the moment the young novice's head appeared out of the hole. Dick Sand, in a word, had told all to his companions. Seizing his gun, followed by Hercules, Acteon, and Bat, he reappeared at the summit of the cone, and all fired on one of the boats. Several natives fell, and yells, accompanied by shots, replied to the detonation of the fire-arms. But what could Dick Sand and his companions do against a hundred Africans, who surrounded them on all sides? The ant-hill was assailed. Mrs. Weldon, her child, and Cousin Benedict, all were brutally snatched from it, and without having had time to speak to each other or to shake hands for the last time, they saw themselves separated from each other, doubtless in virtue of orders previously given. A last boat took away Mrs. Weldon, little Jack and Cousin Benedict. Dick Sand saw them disappear in the middle of the camp. As to him, accompanied by Nan, Old Tom, Hercules, Bat, Acteon and Austin, he was thrown into a second boat, which went toward another point of the hill. Twenty natives entered this boat. It was followed by five others. Resistance was not possible, and nevertheless, Dick Sand and his companions attempted it. Some soldiers of the caravan were wounded by them, and certainly they would have paid for this resistance with their lives, if there had not been a formal order to spare them. In a few minutes, the passage was made. But just as the boat landed, Hercules, with an irresistible bound, sprang on the ground. Two natives having sprung on him, the giant turned his gun like a club, and the natives fell, with their skulls broken. A moment after, Hercules disappeared under the cover of the trees, in the midst of a shower of balls, as Dick Sand and his companions, having been put on land, were chained like slaves. CHAPTER VII. IN CAMP ON THE BANKS OF THE COANZA. The aspect of the country was entirely changed since the inundation. It had made a lake of the plain where the termite village stood. The cones of twenty ant-hills emerged, and formed the only projecting points on this large basin. The Coanza had overflowed during the night, with the waters of its tributaries swelled by the storm. This Coanza, one of the rivers of Angola, flows into the Atlantic, a hundred miles from the cape where the "Pilgrim" was wrecked. It was this river that Lieutenant Cameron had to cross some years later, before reaching Benguela. The Coanza is intended to become the vehicle for the interior transit of this portion of the Portuguese colony. Already steamers ascend its lower course, and before ten years elapse, they will ply over its upper bed. Dick Sand had then acted wisely in seeking some navigable river toward the north. The rivulet he had followed had just been emptied into the Coanza. Only for this sudden attack, of which he had had no intimation to put him on his guard, he would have found the Coanza a mile farther on. His companions and he would have embarked on a raft, easily constructed, and they would have had a good chance to descend the stream to the Portuguese villages, where the steamers come into port. There, their safety would be secured. It would not be so. The camp, perceived by Dick Sand, was established on an elevation near the ant-hill, into which fate had thrown him, as in a trap. At the summit of that elevation rose an enormous sycamore fig-tree, which would easily shelter five hundred men under its immense branches. Those who have not seen those giant trees of Central Africa, can form no idea of them. Their branches form a forest, and one could be lost in it. Farther on, great banyans, of the kind whose seeds do not change into fruits, completed the outline of this vast landscape. It was under the sycamore's shelter, hidden, as in a mysterious asylum, that a whole caravan--the one whose arrival Harris had announced to Negoro--had just halted. This numerous procession of natives, snatched from their villages by the trader Alvez's agents, were going to the Kazounde market. Thence the slaves, as needed, would be sent either to the barracks of the west coast, or to N'yangwe, toward the great lake region, to be distributed either in upper Egypt, or in the factories of Zanzibar. As soon as they arrived at the camp, Dick Sand and his companions had been treated as slaves. Old Tom, his son Austin, Acteon, poor Nan, negroes by birth, though they did not belong to the African race, were treated like captive natives. After they were disarmed, in spite of the strongest resistance, they were held by the throat, two by two, by means of a pole six or seven feet long, forked at each end, and closed by an iron rod. By this means they were forced to march in line, one behind the other, unable to get away either to the right or to the left. As an over precaution, a heavy chain was attached to their waists. They had their arms free, to carry burdens, their feet free to march, but they could not use them to flee. Thus they were going to travel hundreds of miles under an overseer's lash. Placed apart, overcome by the reaction which followed the first moments of their struggle against the negroes, they no longer made a movement. Why had they not been able to follow Hercules in his flight? And, meanwhile, what could they hope for the fugitive? Strong as he was, what would become of him in that inhospitable country, where hunger, solitude, savage beasts, natives, all were against him? Would he not soon regret his companion's fate? They, however, had no pity to expect from the chiefs of the caravan, Arabs or Portuguese, speaking a language they could not understand. These chiefs only entered into communication with their prisoners by menacing looks and gestures. Dick Sand himself was not coupled with any other slave. He was a white man, and probably they had not dared to inflict the common treatment on him. Unarmed, he had his feet and hands free, but a driver watched him especially. He observed the camp, expecting each moment to see Negoro or Harris appear. His expectation was in vain. He had no doubt, however, that those two miserable men had directed the attack against the ant-hill. Thus the thought came to him that Mrs. Weldon, little Jack, and Cousin Benedict had been led away separately by orders from the American or from the Portuguese. Seeing neither one nor the other, he said to himself that perhaps the two accomplices even accompanied their victims. Where were they leading them? What would they do with them? It was his most cruel care. Dick Sand forgot his own situation to think only of Mrs. Weldon and hers. The caravan, camped under the gigantic sycamore, did not count less than eight hundred persons, say five hundred slaves of both sexes, two hundred soldiers, porters, marauders, guards, drivers, agents, or chiefs. These chiefs were of Arab and Portugese origin. It would be difficult to imagine the cruelties that these inhuman beings inflicted on their captives. They struck them without relaxation, and those who fell exhausted, not fit to be sold, were finished with gunshots or the knife. Thus they hold them by terror. But the result of this system is, that on the arrival of the caravan, fifty out of a hundred slaves are missing from the trader's list. A few may have escaped, but the bones of those who died from torture mark out the long routes from the . " 1 2 " , . . " 3 4 " , , . . 5 . " 6 7 , , . 8 , 9 . 10 11 . 12 13 " ?
