"Lend a hand here with a lanthorn," I says, running up to the paddle-box. "Easy ahead," says the captain, shouting down the skylight. "No, no!" I shrieked, turning all wet with horror; and then, as the paddle-wheels made about half a revolution, there came such a horrid, stifling, muffled scream as nearly froze us, and then another, but this time a plain one, for I was up atop of the paddle-box and had opened the trap. "Help, help!" came the wild cry from just beneath me, and I called out again for a light, which some one brought, and I lowered it down between two of the floats, when I could see both of the poor fellows--one astride of the wheel axle, and the other half in the water, holding on to one of the spokes; while, by the glimmering of the lanthorn, I could see their horror-stricken countenances, and the peril of their position. Just then one of them tried to say something, but it was only a sort of groan, and to my great horror I saw him throw up his hands wildly, and fall off the axle right down splash into the water, where the bottom floats were underneath, and I made sure he was gone. But there was no time for thinking, if anything was going to be done; and, giving the lanthorn to another man to hold, I got through the trap, and then, climbing about like a squirrel in a cage, I got down to the bottom, and then got hold of the poor fellow who had fallen, and managed to hold his head up, while I shouted for some one to bring a rope. Nobody seemed in a hurry to come down, and I must say as it looked a horrible place, while the water kept dripping from the icy wet floats, and I couldn't help thinking where we should be if the wheels went round. But directly after I saw some one drop through the hole, and then the captain began to climb down with the end of a rope, and we soon made it fast to the poor fellow, and had him up. As for the other chap, he seemed mad with fright, for when we got to him his eyes were fixed and his arms clinging that tightly round one of the spokes that we could not move them. So we had to make the rope as was sent down again fast round him, and at last we got him up through the floats and out of the trap.
