"There are perhaps still living men below," stammered the overseer in a low voice. A plaintive groan as though in answer to his question came to his ears from below the mass of fallen earth. He approached it again, but the groan was not repeated.

"Now, comrades, we must dig!" he said.

"Come you there, Orefieff Smirnoff! Let us get to work."

So speaking, the overseer seized a miner by the hand, led him before the mass of collapsed earth and began to work with him. Hardly had they commenced than a second landslip took place, and the first mass of earth, pressed by the second which had just fallen, spread in liquid mud over the gallery. The two men only leaped back just in time.

The overseer could now properly estimate the magnitude of the disaster. It was evident that they were imprisoned and that no help could reach them from without. But at any rate they could breathe easily, and the fact that the air circulated in the gallery much more freely than before the accident, showed that there was still some means of ventilation left. They must hasten to take advantage of it. In a few hours the whole mine would collapse owing to this immense falling-in of earth.

"Come here quickly, comrades!" said the overseer.

In the twinkling of an eye they surrounded him.

"There is only one way of saving ourselves," he said, "and that is by reaching the old upper gallery. Let those who care for their lives follow me. Perhaps the shaft is still intact on that side. It ought to be so, for the air circulates freely. Call those who are working in the side galleries, and all of you come back here."

Some of the miners, who had preserved more presence of mind than the rest, rushed to the side galleries to summon their companions.
