"I dare say I can go where you do." Dummy nodded, and after handing the second candle to his master, he went along sidewise, and then lowered himself over the edge of the gulf, and dropped out of sight.
"Only 'bout a fathom, Master Mark," he shouted, "and plenty of room." Mark did not hesitate, but lowered himself in turn, and dropped upon his feet, to find they were upon a rugged shelf, about four feet wide, sloping downward right by the side of the gulf; and passing along this, they soon reached the other side of the great chasm, to stand nearly opposite to the end of the passage where they had entered, but about twenty feet lower; and here they again looked down into the awesome depths.

But nothing was to be seen.

The water fell from somewhere beneath where they had entered; and as they judged, plunged deep down into a wide chasm, and from thence ran out and under the great crack, which the boy found out as the way they had to go.
"Stream runs right under that, Master Mark.

I went along some way, and every now an' then I could hear it, deep down.

I say, did you bring anything to eat ?" "Some bread that I couldn't manage at breakfast." "So did I," said the boy.
