I thought over many things which might be comprised in that great wooden chamber. I even tried to remember what sort of a country Peru was, and what articles of commerce would be most likely to be carried there from England. But I could make very little of this train of reasoning, so ignorant was I of commercial geography. One thing was certain: it was what is called an "assorted cargo," for such are the cargoes usually sent to the seaports of the Pacific. I might, therefore, expect to encounter a little of this, and a little of that--in short, everything produced in our great manufacturing cities. After I had spent nearly half an hour in this sort of conjecturing. I began to perceive that it could serve no purpose. It would be only guesswork, at best, and it was evident I could not tell what quality of metal the mine contained, until I had first sunk my shaft. The moment to commence that labour had arrived; and, throwing reflection for the time behind me, I betook myself to the task. CHAPTER FIFTY FIVE. THE LUXURY OF STANDING ERECT. It will be remembered that in my former expedition into the two boxes of cloth--while in hopes of finding more biscuits, or something else that was eatable--I had ascertained the sort of packages that surrounded them, as well as those that were placed above. It will be remembered, also, that on that end of the first cloth-case which lay towards the hatchway I had found a bale of linen; but on the top of the same case rested another of cloth, apparently similar to itself. Into this one on the top I had already effected an entrance; and therefore I could now count upon having made so much way _upward_. By emptying the upper case of its contents, I should thus have gained one clear stage in the right direction; and considering the time and trouble it took to hew my way through the side of one box, and then through the adjacent side of another, this portion of my work already accomplished was a matter of congratulation. I say already accomplished, for it only remained to drag down the pieces of cloth contained in the upper box, and stow them away to the rear. To do this, then, was the first act of my new enterprise, and I proceeded to its execution without further delay. After all, it did not prove a very easy task. I experienced the same difficulty as before, in detaching the pieces of cloth from one another, and drawing them forth from their tightly-fitting places. How-ever, I succeeded in getting them clear; and then taking them, one at a time, I carried, or rather pushed them before me, until I had got them to the very farthest corner of my quarters, by the end of the old brandy-cask. There I arranged them, not in any loose or negligent manner, but with the greatest precision and care; packing them into the smallest bulk, and leaving no empty corners, between them and the timbers, big enough to have given room to a rat.
