At an early age he left home to earn his own living, the first situation he filled being that of servant to a shopkeeper at Sleaford. We next trace him to the city of Lincoln, where he was engaged to wait upon a lady. During his leisure time, he took every opportunity to make weather-glasses and weather-houses. The last situation he held as a gentleman's servant, was under J. Feriman, Esq., who found Andrews so intent on study that he kindly allowed him two or three hours daily to devote to that purpose. We are told that on the 1st of April, 1764, he went to Aswarby Hall, the seat of Sir Christopher Whichcote, to view the eclipse of the sun which was visible on that day. A number of ladies and gentlemen had assembled for the same purpose. Having previously calculated a type of this eclipse, he presented the same to the company, showing them the manner of its appearance in a dark room upon a board, and, after it was over they unanimously declared that his calculations came nearer than any given in the almanacs. Shortly after the above meeting, he opened a school at Basingthorpe, near Grantham. We presume the venture did not prove satisfactory, for we find that he was afterwards engaged as an usher in a clergyman's boarding-school at Stilton. His next move was to Cambridge, hoping there to obtain assistance in prosecuting his studies from the men of science in the University. Accustomed to a quiet life, he could not endure the bustle of that ancient seat of learning, so left and settled at Royston, Hertfordshire, where he opened a school, and continued to reside until the day of his death. He had only reached the age of twenty-three when he took up his residence at the latter town. A few years after Andrews settled there, we find his name on the title-page of an almanac, and an advertisement of his school. The title-page of the publication is curious, and reads as follows:--
