So I went to work; and here I must needs observe that, as reason is the substance and original of the mathematics, so by stating and squaring everything by reason, and by making the most rational judgment of things, every man may be in time master of every mechanic art. I had never handled a tool in my life, and yet in time, by labour, application, and contrivance, I found at last that I wanted nothing but I could have made it, especially if I had had tools; however, I made abundance of things, even without tools, and some with no more tools than an adze and a hatchet, which perhaps were never made that way before, and that with infinite labour; for example, if I wanted a board, I had no other way but to cut down a tree, set it on an edge before me, and hew it flat on either side with my axe, till I had brought it to be as thin as a plank, and then dubb it smooth with my adze. It is true, by this method, I could make but one board out of a whole tree, but this I had no remedy for but patience, any more than I had for the prodigious deal of time and labour which it took me up to make a plank or board; but my time or labour was little worth, and so it was as well employed one way as another. However, I made me a table and a chair, as I observed above, in the first place, and this I did out of the short pieces of boards that I brought on my raft from the ship: but when I had wrought out some boards, as above, I made large shelves of the breadth of a foot and a half one over another, all along one side of my cave, to lay all my tools, nails, and iron-work, and in a word, to separate everything at large in their places, that I might come easily at them; I knocked pieces into the wall of the rock to hang my guns and all things that would hang up. So that had my cave been to be seen, it looked like a general magazine of all necessary things, and I had everything so ready at my hand, that it was a great pleasure to me to see all my goods in such order, and especially to find my stock of all necessaries so great.
