on my back, and stretched a thread with small beads upon it, at arms-length, between my eye and the stars, sliding the beads upon it till they hid such and such stars from my eye, in order to take their apparent distances from one another; and then, laying the thread down on a paper, I marked the stars thereon by the beads, according to their respective positions, having a candle by me. My master at first laughed at me; but when I explained my meaning to him, he encouraged me to go on; and, that I might make fair copies in the daytime of what I had done in the night he often worked for me himself. I shall always have respect for the memory of that man.
'I soon after was introduced by a schoolmaster whom I knew to a Mr. Cantley, an ingenious man, who acted as butler to Thomas Grant, Esq., of Achoynaney, and from whom I received some instruction, particularly in decimal arithmetic, algebra, and the first elements of geometry. He also made me a present of 'Gordon's Geographical Grammar,' which at that time was to me a great treasure. There is no figure of a globe in it, although it contains a tolerable description of the globes, and their use. From this description I made a globe in three weeks at my father's, having turned the ball thereof out of a piece of wood, which ball I covered with paper, and delineated a map of the world upon it, made the meridian ring and horizon of wood, covered them with paper, and graduated them: and I was happy to find that by my globe, which was the first I ever saw, I could solve the problems. But this was not likely to afford me bread; and I could not think of staying with my father, who, I knew full well, could not maintain me in that way, as it could be of no service to him; and he had, without my assistance, hands sufficient for all his work.'
Thinking it would be a very easy matter to attend a mill, and that he would have plenty of leisure for study, poor Ferguson next engaged himself to a miller; but the fellow turned out to be a harsh, ignorant drunkard, who required every moment of the boy's time, starving and ill-using him besides, so that at the end of a year he had to betake himself to the roof of his father. He next hired himself to a farmer; but here, again, he was worked beyond the strength of his naturally delicate constitution: illness ensued, and he had again to seek the paternal refuge. 'In order to amuse myself in this low state, I made a wooden clock, the frame of which was also of wood; and it kept time pretty well. The bell on which the hammer struck the hours was the neck of a broken bottle. Having then no idea how any timekeeper could go but by a weight and a line, I wondered how a watch could go in all positions, and was sorry that I had never thought of asking Mr. Cantley, who could very easily have informed me. But happening one day to see a gentleman ride by my father's house, which was close by a public road, I asked him what o'clock it then was; he looked at his watch, and told me. As he did that with so much good-nature, I begged of him to show me the inside of his watch; and though he was an entire stranger, he immediately opened the watch, and put it into my hands. I saw the spring-box with part of the chain round it, and asked him what it was that made the box turn round; he told me that it was turned round by a steel spring within it. Having then never seen any other spring than that of my father's gun-lock, I asked how a spring within a box could turn the box so often round as to wind all the chain upon it. He answered that the spring was long and thin, that one end of it was
