“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.”
