There is one defect in Mr Fullom’s history which puts his readers to considerable inconvenience—he is not very accurate in his dates. We do not quite make out, for example, when young Douglas made his way into the Academy, or how long he continued a cadet; but we are told, what is extremely probable in itself, that he was much beloved by his contemporaries, and that he soon took the lead among them both in the playground and in the class-room. His passion for naval affairs continued as strong as ever, and he indulged it by frequent boat excursions on the Thames. He swam, also, like a duck, and paid many a furtive visit to Deptford dockyard, where he studied by fits and starts the art of shipbuilding. His vacations he spent in Scotland, passing to and from Leith in one of the smacks;—an intense delight to him, because he was instructed by the crews in the arts of knotting and splicing, of plaiting points and gaskets, of making gammets, and heaving the lead. It is not often that a youth displays such unmistakable aptitude for a career which he is not destined to follow; and it still more rarely happens that the amusements of the boy, whom circumstances in after life place in a groove apparently wide apart from them, turn out to have been by no means the least useful branches of his education, either to himself or to others. After completing his college course, Douglas received a lieutenant’s commission, and in 1795 assumed the command of a small artillery corps in the north of England. His headquarters were in Tynemouth Castle, and he had detachments at Sunderland, Hartlepool, and Berwick-upon-Tweed. His entire force in gunners fell short of fifty men; yet this was at a time when the risk of invasion appeared to be imminent, and Douglas and his gunners were necessarily exposed to bear the brunt of it. The young lieutenant felt how perfectly inefficient his force was, and cast about to devise some means of increasing it. He asked first for a reinforcement of artillerymen, which could not be afforded. He then suggested to the general officer of the district the propriety of drilling a portion of his infantry to the great-gun exercise; and himself, with unwearied diligence, instructed thirty men from each of the regiments quartered within many miles of Tynemouth. He was not, however, satisfied even with this—the thought struck him that he might enlist the sympathies of the fishermen and coasting sailors in the cause which he had at heart; and having obtained through General Balfour the sanction of the Government, he invited them to form themselves into companies of volunteer artillery. Upwards of five hundred fine fellows answered to the call; and the thoughtful lad had soon the satisfaction of knowing that danger, if it did come, would not find him unprepared, and that the merit of having provided a remedy for a great and acknowledged evil was entirely his own.
