Sim untied one of the ends of the rope, and was pulling it in, when I felt a consciousness that something was wrong, though I could not tell what. It flashed across my mind that I was making a blunder.

"Hold on, Sim!" I shouted, jumping down from the platform, and trying to catch the rope; but the end had gone ashore.

"What's the matter, Buck?" called Sim, apparently alarmed by my sudden movements.

"I have forgotten my money!" I exclaimed, as I leaped on the small raft which lay alongside.

I sprang for the tree to which the great raft was fastened, in order to secure the rope; but it was too late. The current started the raft, and dragged the rope off before I could catch hold of it. In the darkness and the night the craft went off without me.

"Don't leave me, Buck!" called Sim.

"Take the steering oar, and run her up to the shore!" I replied.

I had the small raft, and I could follow at pleasure, and join my companions; but if I pushed off, I could not return, for the branch of the creek was too deep for me to use the pole. I could not think of going without my money.

I saw Sim jump upon the platform, and work the steering oar vigorously, but with more power than skill. He succeeded in running her up to the bank.

"Now hold on to her!" I shouted. "I shall not be gone long!"
