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!"
