In the midst of a variety of conflicting ideas as to what constitutes the best head-dress, the uncomfortable chaco still holds its unsightly place as a component of sapper uniform. Top-heavy for the drivers in riding, the chaco forms no part of their uniform, and so the forage-cap is made to do double duty. The fatigue jacket is of red cloth. Loose and suitable for working it descends as low as the hips, but is militarized by blue cloth pointed cuffs, single twisted shoulder-cords of yellow worsted, and a blue cloth rounded collar. As before, the buttons are small and convex, bearing the garter device, and worn about an inch apart, evincing less coxcombry than in the defunct days of close buttons. All the non-commissioned officers wear gold chevrons and gold single twisted shoulder-cords. Scarlet jackets, after the fashion of the fatigue ones, are worn by all ranks on drill parades and in walking. In addition to their chevrons the sergeants and colour-sergeants wear embroidered crowns, the latter rank being distinguished from the former by a fourth chevron. Besides the plain single-breasted blue surtout, modernized with a rounded collar, the staff-sergeants appear, on parade occasions, in scarlet jackets with the badge of their rank, gold studs down the front, and dark blue silk velvet cuffs and collar, both trimmed with Russia gold braid, and finished with what the tailors, in the poetry of their trade, term crowsfeet. There are no buttons on the jacket, except two on each cuff and two to sustain the double shoulder-cord. The fronts are closed by hooks and eyes. The cloth forage-cap—a delicate institution of peaceable times—was set aside by the adoption of a small Kilmarnock bonnet and chin-strap, well suited for the rough usages of war. Worn with a dragoonish air in the day, it offers itself as a substitute for a pillow at night without the fear of spoiling its shape. It is of dark blue wool banded with a yellow stripe manufactured in the web and decorated with a brass boss in the centre of the crown. The buglers wear the distinction of a pair of crossed trumpets on the front of the cap, while the sergeants and staff-sergeants have small dark-blue cloth caps with large projecting peaks, trimmed with scarlet piping and gold lace bands. The crown of the cap, à la cavalry, is formed of eight pieces—a curious fancy—radiating from the centre and covered at the point of union with a gold netted convex boss. The band of the staff-sergeants is wider and richer than that of the sergeants.
