The recruiting was carried on by the captains of companies, assisted by seven other officers of engineers, with several transferred soldiers of the royal artillery, at Landguard Fort, Tynemouth, Dover, Guernsey, Edinburgh, Fort George, and Berwick. They were not restrained from putting into operation any measure which seemed to be best calculated for obtaining recruits. There was no standard as to height fixed; but labourers were not enlisted over twenty-five years of age, nor any artificer over thirty, unless he had been employed as a mechanic in the Ordnance department, and known to be an expert workman of good character. All recruits, however, whether previously under the Ordnance or not, were “to be strong able-bodied men, free from all infirmity, and duly qualified for their several trades and occupations.” The miners were all got from Cornwall. The bounty given at first was five guineas to each attested recruit; which, on the 21st November, 1787, was reduced to the usual peace allowance of three guineas. These general instructions for recruiting were soon afterwards[78] much altered by the Duke of Richmond, who was anxious to make the corps as perfect as possible with regard to tradesmen. On the decision of his Grace all the men were afterwards enlisted as labourers at 6_d._ a-day. The bounty was continued at three guineas. Growing lads from sixteen to eighteen years of age, not under five feet four inches high, were preferred before all others, and were instructed in the trades most required by the corps. Over eighteen years of age none were taken less than five feet six inches. ----- Footnote 78: In a letter bearing date 19th March, 1788. ----- This was a measure of just precaution, as several men had already enlisted as artificers, who upon a fair trial were found to know but little of their craft. The Duke now thought to insure his object by enlisting every man as a labourer, and after a few months' experience of his abilities, promoting him to be an artificer, or retaining him as a labourer, until recommended for preferment. On promotion to artificers, each man received a bonus or reward of two guineas, an additional 3_d._ a-day pay, and was distinguished from a labourer by being allowed finer clothing and a gold-laced hat.[79] “I think,” wrote his Grace, “that this method, although the slowest, will in the end be the best means of acquiring a good corps of artificers.” Whatever may have been the result of this change, it shows that the Duke was interested in the most trifling concerns of the corps; so much so indeed, that the men were aware of it, and familiarly styled his measures and arrangements “Richmond’s whims.” ----- Footnote 79:
