At that time, I attended the Grammar School. Of the rudiments taught, I was fondest of drawing, geometry, and Euclid. Indeed, I went twice through the first two books of the latter before I was twelve years old. At this age I was sent to the Edinburgh Academy, my eldest brother William being then a medical student at the University. I remained at Edinburgh two years. My early progress in mathematics would have been lost in the classical training which was then insisted upon at the academy, but for my brother who was not only a good mathematician but an excellent mechanic. He took care to carry on my instruction in that branch of knowledge, as well as to teach me to make models of machines and buildings, in which he was himself proficient. I remember, in one of my journeys to Edinburgh, by coach from Darlington, that a gentleman expressed his wonder what a screw propeller could be like; for the screw, as a method of propulsion, was then being introduced. I pointed out to him the patent tail of a windmill by the roadside, and said, "It is just like that!" In 1844 my mother died; and shortly after, my brother having become M.D., and obtained a prize gold medal, we returned to Scarborough. It was intended that he should assist my father; but he preferred going abroad for a few years. I may mention further, with relation to him, that after many years of scientific research and professional practice, he died at Hong Kong in 1858, when a public monument was erected to his memory, in what is known as the "Happy Valley." I remained for a short time under the tuition of my old master. But as the time was rapidly approaching when I too must determine what I was "to be" in life. I had no hesitation in deciding to be an engineer, though my father wished me to be a barrister. But I kept constant to my resolution; and eventually he succeeded, through his early acquaintance with George Stephenson, in gaining for me an entrance to the engineering works of Robert Stephenson and Co., at Newcastle-upon-Tyne. I started there as a pupil on my fifteenth birthday, for an apprenticeship of five years. I was to spend the first four years in the various workshops, and the last year in the drawing-office. I was now in my element. The working hours, it is true, were very long,--being from six in the morning until 8.15 at night; excepting on Saturday, when we knocked off at four. However, all this gave me so much the more experience; and, taking advantage of it, I found that, when I had reached the age of eighteen, I was intrusted with the full charge of erecting one side of a locomotive. I had to accomplish the same amount of work as my mate on the other side, one Murray Playfair, a powerful, hard-working Scotchman. My strength and endurance were sometimes taxed to the utmost, and required the intervals of my labour to be spent in merely eating and sleeping.
