The boy's education was confined to the common elements of reading, writing, and arithmetic, which he partly acquired at the parish school of Strathbungo near Glasgow, and partly at the Chapel School, as it was called, in the Gorbals at Glasgow. He had finally left school before he was fourteen. Some time before he left, he had been partially set to work, and earned four shillings a week by employing a part of each day in driving a small condensing engine which his father had put up in a neighbouring quarry. After leaving school, he was employed for two years as a gig boy on one of the winding engines at the Govan colliery. His parents now considered him of fit age to be apprenticed to some special trade, and as Beaumont had much of his father's tastes for mechanical pursuits, it was determined to put him apprentice to a working engineer. His elder brother John was then acting as engineman at Oakbank near Glasgow, and Beaumont was apprenticed under him to learn the trade. John was a person of a studious and serious turn of mind, and had been strongly attracted to follow the example of the brothers Haldane, who were then exciting great interest by their preaching throughout the North; but his father set his face against his son's "preaching at the back o' dikes," as he called it; and so John quietly settled down to his work. The engine which the two brothers managed was a very small one, and the master and apprentice served for engineman and fireman. Here the youth worked for three years, employing his leisure hours in the evenings in remedying the defects of his early education, and endeavouring to acquire a knowledge of English grammar, drawing, and mathematics. On the expiry of his apprenticeship, Beaumont continued for a time to work under his brother as journeyman at a guinea a week; after which, in 1814, he entered the employment of William Taylor, coal-master at Irvine, and he was appointed engine-wright of the colliery at a salary of from 70L. to 80L. a year. One of the improvements which he introduced in the working of the colliery, while he held that office, was the laying down of an edge railway of cast-iron, in lengths of three feet, from the pit to the harbour of Irvine, a distance of three miles. At the age of 23 he married his first wife, Barbara Montgomerie, an Irvine lass, with a "tocher" of 250L. This little provision was all the more serviceable to him, as his master, Taylor, becoming unfortunate in business, he was suddenly thrown out of employment, and the little fortune enabled the newly-married pair to hold their heads above water till better days came round. They took a humble tenement, consisting of a room and a kitchen, in the Cowcaddens, Glasgow, where their first child was born.
