Ten minutes later they saw two heads appear above, and instantly withdrew their feet from the bucket and made a stroke to the side, which was but four feet distant, being careful as they did that no motion was imparted to the rope. Then though it was too dark to see anything, they heard the bucket lifted from the water. A minute later it fell back again with a splash, then all was quiet.

"We are safe now, and can take our place in the bucket. They are satisfied that if we did jump down here we are drowned. And now we must think about climbing up."

"Aye, that will require a good deal of thinking," Ralph grumbled.

For some time there was silence; then Walter said, "The first thing to do is to cut off the slack of the rope, there are some twelve feet of it. Then we will unwind the strands of that. There are five or six large strands as far as I can feel; we will cut them up into lengths of about a couple of feet and we ought to be able to tie these to the rope in such a way as not to slip down with our weight. If we tie them four feet apart we can go up step by step; I don't see much difficulty about that."
