As soon as the arduous toil of the day was over, and we had partaken of food, we were ready for sleep; so this time Jack Penny was set to watch with Ti-hi and Gyp, and we lay down on a bough-made bed.
One moment I was lying on my back gazing up at the stars, and first thinking of my mother and how anxious she must be as to how I was getting on; then wondering where my father was likely to be, and whether we were going to work in the best way to find him; the next moment I was dreaming that Gyp had run after and caught a wild man of the woods by the tail, and had dragged him into camp, howling dismally.
It did not fit into my dream that wild men of the woods were not likely to be possessed of tails for Gyp to tug, and if they were, that they would have striven to crush the dog by one blow of the hand; my dream arranged itself, and the howling was continued as I started up, all wakefulness, and saw a dark figure bending over me and looking colossal as seen against the ruddy light of the fire.
"Is that you, doctor ?" I said.
"Yes, Joe; wake up.

I want you." "What's the matter--has that horrible thing come again ?" "No," he said; "the black is very bad." "What! old Jimmy ?" I cried.
"Yes.

That is he howling." I jumped up with a curious sensation of suffocation at my chest, for, startled from a deep sleep into wakefulness, it occurred to me that something dreadful was going to happen, and that we were to lose the true-hearted, merry, boyish companion of so many years.

Like a flash there seemed to come back to me the memory of dozens of expeditions in which he had been my faithful comrade, and this was like a death-blow to our hopes, for, in spite of his obstinacy and arrogance, Jimmy would have laid down his life to serve me.
"Let us go to him, doctor," I said.

"Make haste!" Our way to the black lay past the camp fire, where Jack Penny was sitting with Ti-hi, and the former spoke excitedly as we drew near: "I say, doctor, do make haste and give him a dose of something to do him good, or else put him out of his misery." "Jack!" I said in disgust.
"Well, he's awful bad, you know, and he ought to have something.
