In this instance they have been mentioned, not so much for the interest of the general reader, as to preserve them. With those whose names have already been noted, these constitute the first race of non-commissioned officers in the corps. ----- Footnote 25: By the Chief Engineer’s Order of 27th October, 1781, sergeant Macdonald, an active and good non-commissioned officer, was appointed to inspect and take care of all the drains throughout the fortress in the room of sergeant-major Bridges, as also to keep the keys of the gratings, and to see them locked, to prevent ingress or egress by their means. This duty was considered a very important one, both from the facility the drains afforded for the entrance of the enemy and for desertions from the place, and also from the health of the garrison being in a great measure affected by their state. Not unfrequently during heavy rains, the gravel on the rock, washed down by the torrent, would rush into the drains and choke them up. To clear them, the company of artificers was invariably called upon, often at night; and on one occasion, in April, 1813, private William Liddle, who was foremost in one of the great drains, after unlocking the grating, was carried down the sewer with the flood into the sea, and drowned. ----- Footnote 26:
