The scrapings became more and more audible. They could hear the little stones grate under the pressure of a sharp instrument and fall down outside.
"Some creature in its burrow," said Captain Mangles.
Glenarvan, with bewildered gaze, stood astonished.
"Who knows," said he, "but that it is a man?"
"Man or animal," replied the major, "I will know what is going on."
Wilson and Olbinett joined their companions, and all began to dig in the wall, the captain with his poniard, the others with stones pulled out of the ground, or with their nails, while Mulready, stretched on the earth, watched the group of natives through the loop-hole of the mat. But they were motionless around the fire, and did not suspect what was transpiring twenty paces from them.
The soil was loose and crumbling, and lay upon a bed of clay, so that, in spite of the want of tools, the hole rapidly enlarged. It was soon evident that somebody, clinging to the sides of the pah, was making a passage in its outer wall. What could be the object? Did he know of the existence of the prisoners, or could a mere chance attempt at escape explain the work that seemed nearly completed?
HEAVENLY HELP FROM AN EARTHLY HAND.
The captives redoubled their efforts. Their lacerated fingers bled, but still they dug on. After half an hour's labor, the hole they were drilling had reached a depth of three feet. They could perceive by the sounds, which were now more distinct, that only a thin layer of earth prevented immediate communication.
A few moments more elapsed, when suddenly the major drew back his hand, which was cut by a sharp blade. He suppressed a cry that was about to escape him. Captain Mangles, holding out his poniard, avoided the knife that was moving out of the ground, but seized the hand that held it. It was the hand of a woman or a youth, a European hand. Not a word had been uttered on either side. There was plainly an object in keeping silent.
