Dick Sand Part 48

Could they, without running the danger spoken of by d.i.c.k 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 s.p.a.ce 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, d.i.c.k 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?

d.i.c.k 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 d.i.c.k 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 d.i.c.k Sand; "but where will this level stop?"

"Mr. d.i.c.k," 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 d.i.c.k Sand.

"No, Mr. d.i.c.k, 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 d.i.c.k 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. d.i.c.k," 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 ma.s.s, 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 pa.s.sed away. d.i.c.k Sand then thought that Bat had succeeded in pa.s.sing outside when the black emerged.

"Well!" exclaimed d.i.c.k Sand.

"The hole is stopped up by rubbis.h.!.+" 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."

d.i.c.k 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.

d.i.c.k 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 d.i.c.k Sand proposed.

It was one foot above the interior level, consequently seven feet from the ground, that d.i.c.k 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?

d.i.c.k 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 s.p.a.ce, reduced every moment, in a medium already saturated with carbonic acid.

The best tool d.i.c.k 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 d.i.c.k 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 ma.s.s.

"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 s.p.a.ce 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, d.i.c.k 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 d.i.c.k 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.
