This operation consisted simply in stretching myself in a new position, and drawing a fold or two of the broadcloth over me, to keep me from getting chilled while asleep.

For the first week after leaving port, I had found it very cold, for it was the winter season when we left home. The cloth, however, after it was discovered, enabled me to wrap up snugly enough, and I no longer cared for the cold. After a time, however, I began to perceive that the cold had quite taken its departure, and each day and night the atmosphere in the hold of the ship appeared to be growing warmer. On the night after the storm had passed, it did not feel at all cold, and the slightest covering sufficed.

At first, I was surprised by this sudden change in the state of the atmosphere; but when I reflected a little, I was able to explain it to my satisfaction. “Beyond a doubt,” thought I, “we have been all the while sailing southward, and we are getting into the hot latitudes of the torrid zone.”

I knew but little of what that meant, but I had heard that the torrid zone—or the tropics, as it was also called—lay to the south of England; and that there the climate was hotter than the hottest summer day at home. I had also heard that Peru was a southern country, and therefore we must be going in a southerly direction to reach it.

This was a very good explanation of the warm weather that had set in. The ship had now been sailing for nearly two weeks; and allowing her to have made two hundred miles a day (and ships, I knew, often go faster than that), she would at this time be a long way from England, and in a different climate altogether.

Thus reasoning with myself, I contrived to pass that afternoon and evening, and as I felt the hands of my watch indicating the hour of ten, I resolved, as already stated, to eat the half biscuit, and then go to sleep.

I first drew a cup of water, so that the biscuit might not be eaten dry; and, this done, I stretched forth my hand for the bread. I knew the exact spot where it lay, for I had a little corner, just alongside the great beam, where I kept my knife and cup, and wooden almanack—a sort of little shelf, raised by a roll of the cloth above the common level of my cell. There I had placed the half biscuit, and there, of course, I could lay my hand upon it as well without a light as with one. So perfectly had I become acquainted with every corner of my apartment, and every crevice leading from it, that I could place my finger on any given spot of the size of a crown-piece, without the slightest deviation.

I reached forth my hand, then, to clutch the precious morsel. Judge my astonishment when I touched the spot where I supposed it to be lying, and found it was not there!

At first, I fancied I might be mistaken—that perhaps I had not left it in the usual place on my shelf. There it certainly was not.

I felt the cloth cup, for that was in my hand full of water. The knife was in its place—so, too, the little notched stick, and the pieces of the string which I had used in measuring the butt—but no half biscuit!
