We left the major and his party marooned in the cave, and overcome by the suddenness of the disaster that had overtaken them like a bolt from a clear sky. We must now return to them.

After the first shock of the discovery the major suggested that they retreat to the chamber and talk things over as calmly as possible. Each one of the party, with a strong effort to master his feelings, followed the advice. A long consultation followed, the result of which was that they determined that the first thing to be done was to institute a search for water.

The far end of the cavern had not yet been explored and it was decided to begin with that. Headed by the major, they started for what seemed a blank wall at the end of the chamber. But on nearing it, it proved that its appearance of blankness was chiefly caused by a sort of screen of rock that masked an opening as effectually as if it had been placed there by someone anxious to conceal it.

“We’ll penetrate beyond this,” announced the major, and holding his lantern high, was stepping forward when he stopped. One word came to his lips:

“Water!”

From a tiny rift in the rock, sure enough, a small but blessed stream of clear water was flowing. The delight with which the imprisoned party hailed the discovery may be imagined. For a short time, while they assuaged their pangs of thirst, already painful, they almost forgot the seriousness of their situation.

While the others drank, Andy Bowles, who had been one of the first to taste the cool water, strayed further into the passage. Presently his voice was borne back to the others.

“Say!” he cried; “there’s a funny sort of box in here.”

“What kind of a box?” hailed the major, alert in an instant.

“Why, it’s awful old by the looks of it. It’s all bound with iron, and nails are stuck all over it. And—say! There are two more back beyond it.”
