he, 'are you a married man?' I told him I had been so ever since May, in the year 1739. He said he was sorry for it, because it quite defeated his scheme, as the master of the school he had in view for me must be a bachelor.
'He then asked me what business I intended to follow. I answered that I knew of none besides that of drawing pictures. On this he desired me to draw the pictures of his wife and children, that he might show them, in order to recommend me to others; and told me that when I was out of business, I should come to him, and he would find me as much as he could—and I soon found as much as I could execute; but he died in a few years after, to my inexpressible grief.
'Soon afterwards it appeared to me, that although the moon goes round the earth, and that the sun is far on the outside of the moon's orbit, yet the moon's motion must be in a line—that is, always concave towards the sun; and upon making a delineation representing her absolute path in the heavens, I found it to be really so. I then made a simple machine for delineating both her path and the earth's on a long paper laid on the floor. I carried the machine and delineation to the late Martin Felkes, Esq., president of the Royal Society, on a Thursday afternoon. He expressed great satisfaction at seeing it, as it was a new discovery; and took me that evening with him to the Royal Society, where I showed the delineation, and the method of doing it.
'In the year 1747, I published a dissertation on the phenomena of the harvest moon, with a description of a new orrery, in which there are only four wheels. But having never had grammatical education, nor time to study the rules of just composition, I acknowledge that I was afraid to put it to press; and for the same cause, I ought to have the same fears still. But having the pleasure to find that this my first work was not ill received, I was emboldened to go on in publishing my 'Astronomy,' 'Mechanical Lectures,' 'Tables and Tracts relative to several Arts and Sciences,' a small treatise on 'Electricity,' and 'Select Mechanical Exercises.'
'In the year 1748, I ventured to read lectures on the eclipse of the sun that fell on the 14th of July in that year. Afterwards I began to read astronomical lectures on an orrery which I made, and of which the figures of all the wheelwork are contained in the 6th and 7th plates of 'Mechanical Exercises.' I next began to make an apparatus for lectures on mechanics, and gradually increased the apparatus for other parts of experimental philosophy, buying from others what I could not make for myself. I then entirely left off drawing pictures, and employed myself in the much pleasanter business of reading lectures on mechanics, hydrostatics, hydraulics, pneumatics, electricity, and astronomy; in all which my encouragement has been greater than I could have expected.'
To this narrative we shall add the few particulars which are necessary to complete the view of Ferguson's life and character. It was through the zeal of George III in behalf of science, that Ferguson was honored with the royal bounty of £50 a-year. His majesty had attended some of the lectures of the ingenious astronomer, and often, after his accession, sent for him to converse upon scientific topics. He had the extraordinary honor of being elected a member of the Royal Society, without paying either the initiatory or the annual fees, which were dispensed with in his case, from a supposition of his being too poor to pay them without inconvenience.
