Some incidental services executed by the sappers were of a character which it may not be considered inappropriate to notice. So various were their duties and so frequent the calls for their assistance, that the encomiums passed upon them after a full test of their usefulness were not extravagant when it was said “that in all their capacities, from the driving of a nail to the marking out of a fortification, they seemed to be equally as _au fait_ as if each service was their special and sole vocation.”[122] They repaired and adapted the poor-house at Burrow Hill for a general hospital; erected a flag-staff for displaying the royal standard; enclosed a large area of ground with a canvas wall seven feet high, within which were pitched marquees and different tented conveniences for the use of the Queen and Her Majesty’s Consort and guests; and watched and managed the tent-ropes of the royal pavilion, &c., within the compound. Here likewise they erected a cookhouse of brick, after the form of their own kitchen, and cut a road about two miles long, from Colonel Challoner’s plantation to the “Magnet,” as a carriage drive for Her Majesty. The road led across one of the artificial sheets of water, and at either side of this causeway was fixed a temporary railing, which gave it an appearance of strength and completeness. Contrivances were also adopted for permitting the water to run freely through the embankment so as to insure the stream rising to the same level at both sides of the bridge. The road was, moreover, a useful one, for in manœuvring the troops it was sometimes employed to accelerate their movements, and the passage across it formed a grand feature in the reviews. It was called the “Queen’s Road,” and the dam across the sheet of water was dignified with the name of the “Queen’s Bridge.” The sappers also attended to the pitching and adjusting of the marquees of some of the staff officers; drained the camp ground; taught soldiers of the line the readiest methods of effecting these duties, and built several sentry-boxes. One was erected under the superintendence of a French captain, of rough poles driven into the ground in a circle, after the manner of the initial gabion. In front, one stake was omitted for the entrance. The box was built to the usual height, was covered in with a conical top, and the whole was thatched with, straw in courses, which gave it in the distance, when the sun was shining upon it, the semblance of a richly-flounced dress. Another box of this kind revolved on a pivot at pleasure, to screen the sentry from wind or rain; and after the camp was broken up, it was given a place in the grounds of Colonel Challoner. A third was run up by private James Queen,[123] which, from its mechanical pretensions, was applauded as a work of taste, but could never be successfully imitated unless by talented workmen accustomed to build with neatness and exactness.
