¶ In 1834, possibly as a result of the newly organized dragoons receiving distinctive branch insignia, the infantry and artillery once again were authorized devices on the dress cap designating their particular arm. The gilt eagle was retained. Below the eagle was an open horn with cords and tassels in silver for infantry, and cross cannons in "gilt" for artillery. The number of the regiment was added over the cannon or within the curve of the horn. These devices remained in use until the change in headgear in 1851. CAP INSIGNIA, INFANTRY, 1834-1851 _USNM 62055-M, 62056-M (SK-1808, 1809). Figure 39._ [Illustration: FIGURE 39] This eagle is similar to the 1821 pattern, although somewhat more compact in design. It is struck in brass, has wings upraised, head to the right, shield on breast, olive branch in right talon, and three arrows in left talon. The open horn, struck in brass and silvered, is suspended, with bell to the right, by four twisted cords tied in a 3-leaf-clover knot; the tassels on the four cord-ends hang below. CAP INSIGNIA, ARTILLERY, 1834-1851 _USNM 60426-M (S-K 182). Figure 40._ [Illustration: FIGURE 40] This is the "gilt ... cross cannons" device prescribed for artillery in the 1834 regulations. Struck in sheet brass of medium thickness, the superimposed cannon has trunnions and dolphins. FORAGE CAP STAR, DRAGOON OFFICER, C. 1840 _USNM 604967-M (S-K 1111). Figure 41._ [Illustration: FIGURE 41] Although uniform regulations for the period of the 1830's and 1840's make no mention of a distinctive device for the dragoon forage cap, photographs in the National Archives show that officers' caps, at least, carried a 6-pointed star, apparently gold-embroidered.[75] This specimen is believed to be such a star. Made of gold bullion and with rather large sequins sewed onto a heavy paper background, the star is mounted on dark blue wool. The points of the star are extended with gold embroidery on the cloth.

CADET'S, U.S. MILITARY ACADEMY, 1842, AND ENGINEER SOLDIERS, 1846 _USNM 604529 (S-K 676) Figure 42._ [Illustration: FIGURE 42] In 1839 the cadets at the Military Academy discarded the bell-crowned caps they had worn since 1821 and wore a cylindrical black shako similar to that worn by the Regular artillery and infantry. The artillery gilt eagle and crossed cannon replaced the diamond-shaped plate on the front. In 1842-1843 the crossed cannon were replaced by the engineer castle as more in keeping with the original mission of the Academy and the general orientation of its curriculum.
