The illustrated cap and plate is very similar to the ones worn by the Boston Light Infantry[120] about 1839-1840 except that the upper or "mortar board" portion is beige instead of red and the plate is a full instead of a three-quarter sunburst. The mortar board form is that introduced by the Polish lancers in Europe in the early years of the 19th century and worn by most European lancer regiments of the same period. Lancer units in the British Army adopted this type cap in 1816 when they were first converted from light dragoons.[121] The large, brass, eagle-on-sunburst plate was obviously patterned after the one prescribed for the Regular dragoons in 1833.

Figure 155._ [Illustration: FIGURE 155] As an example of more than a dozen known variants of the eagle, this silver-on-copper specimen is illustrated to show the general form and size of Militia cockade eagles that became distinct types in the 1830's and continued until about 1851. All such eagles were obviously stock patterns. COCKADE EAGLE, C. 1836 _USNM 604960-M (S-K 1104). Figure 156._ [Illustration: FIGURE 156] This gold-embroidered cockade eagle with a wreath of silver lame about its breast appears to have been patterned directly after the eagle on the 1833 Regular dragoon cap plate (see fig. 38). It possibly is one of a type worn by general officers of Militia. On this specimen, both the eye and mouth of the eagle are indicated with red thread. COCKADE EAGLE, C. 1836 _USNM 604959-M (S-K 1103). Figure 157._ [Illustration: FIGURE 157] This gold-embroidered eagle, with wings and tail of gold embroidery and gold sequins, was worn by staff and field officers, and possibly general officers, of Militia. A duplicate on an original chapeau is in the collections of the Maryland Historical Society in Baltimore, Maryland. Eagle ornaments such as this were generally centered on a round cloth cockade about 6 inches in diameter. The eagle's mouth is indicated by embroidery with red thread. Similar eagles of a smaller size are known on epaulets of the same period. CAP PLATE, C. 1840 _USNM 60451l-M (S-K 658). Figure 158._ [Illustration: FIGURE 158] The flaming grenade, adopted by the Regulars in 1832 after long usage by the British and other foreign armies, was quickly adopted by the Militia. This specimen, of silver-on-copper, was worn as a cap plate either in conjunction with another device below it on the cap front or as a lone distinctive ornament. It cannot precisely be identified as an artillery plate, but since some Militia artillery units are definitely known to have worn silver buttons of the artillery pattern, such is highly probable. Also known in brass and in smaller sizes, it is a stock pattern. CAP PLATE, C. 1840 _USNM 604526 (S-K 673). Figure 159._ [Illustration: FIGURE 159]
