Worn attached to the base of the pompon by all enlisted personnel, this brass eagle, similar in general design to that worn on the shako in the 1830's, stands with wings upraised, olive branch in right talon, three arrows in left talon, and a scroll, with national motto, in beak. Above are stars, clouds, and bursts of sun rays. Officers wore an eagle of similar design of gold embroidery on cloth. CAP INSIGNIA, GENERAL AND STAFF OFFICERS, 1851 _USNM 604862 (S-K 1007). Figure 44._ [Illustration: FIGURE 44] This specimen, in accord with regulations, is on dark blue cloth and consists of a gold-embroidered wreath encircling Old English letters "U.S." in silver bullion. Embroidered insignia of this period were all made by hand, and they varied considerably in both detail and size. During the 1861-1865 period the same design was made about half this size for wear on officers' forage caps, and the device appeared in variant forms. One example is known where the numeral "15" is embroidered over the letters "U.S.";[79] and Miller's _Photographic History of the Civil War_ includes several photos of general officers whose wreath insignia on the forage cap substitute small rank insignia stars for the letters. [Footnote 79: LEWIS, p. 64.] CAP INSIGNIA, OFFICER, ENGINEERS, 1851 _USNM 300720. Figure 45._ [Illustration: FIGURE 45] On dark blue cloth, this device comprises a gold-embroidered wreath of laurel and palm encircling a turreted castle in silver metal as prescribed in regulations. Other examples are known with the castle embroidered. HAT INSIGNIA, OFFICER, ARTILLERY, 1851 _USNM 604872 (S-K 1017). Figure 46._ [Illustration: FIGURE 46] This specimen adheres almost exactly to the 1851 regulations, but it lacks the number of the regiment as called for. The number was a separate insignia embroidered above the cannon. The cannon are of gold embroidery. The device was also made in gold metal imitation-embroidery in several variant designs. CAP INSIGNIA, OFFICER, INFANTRY, 1851 _USNM 604888 (S-K 1033). Figure 47._ [Illustration: FIGURE 47] On dark blue cloth, this device is the well-known looped horn in gold embroidery with three cords and tassels. The regimental number "4," in silver bullion, lies within the loop of the horn. This insignia is also common in metal imitation-embroidery.

Figure 48._ [Illustration: FIGURE 48] Struck in brass, this device was worn on the caps and coat collars of ordnance enlisted personnel. Although the shell and flame insignia appears in a number of variations of design, this specimen conforms exactly to the regulations of 1851 as published by Horstmann.
