The eagle on this brass plate is similar to the ones on the preceding shield plates, but the Federal shield on which he stands is ornamented with three star devices composed of smaller stars. An unusual feature of this plate is the addition of the flaming portion of a grenade rising from the eagle's head, a device not a part of any other known cap plate. This symbol suggests artillery, and the plate is of the proper color. Although an unusual over-all design, the lack of any components of state arms or crests indicate that it may have been a stock pattern. The reverse is fitted with two simple bent-wire fasteners. CAP PLATE, MASSACHUSETTS INFANTRY, C. 1830 _USNM 60355-M (S-K 111). Figure 132._ [Illustration: FIGURE 132] This silver-on-copper plate bears the familiar elements of the Massachusetts seal: Indian, in hunting shirt, with bow in right hand, arrow with point downward in left hand, and star above right shoulder. The crest--an arm grasping a broad sword on a wreath of the colors--is superimposed on a burst of sun rays above. The State's motto is written around the shield. The earlier plates containing elements of state arms were for the most part confined to the States of Massachusetts, Connecticut, and New York. No large plates bearing Pennsylvania State symbols that can be dated prior to 1835 are known. This seal was not authorized by law until 1885. However, the devices and the motto were elements of the seal of the Commonwealth of Massachusetts ordered prepared by the state legislature in 1780 and, although apparently never formally approved, used as such for many years. It differs considerably in detail from the seal in use from 1629 to 1684.[109] [Footnote 109: See ZIEBER, pp. 141-144.] CAP PLATE, MASSACHUSETTS INFANTRY, C. 1835 _USNM 60316-M (S-K 72). Figure 133._ [Illustration: FIGURE 133] This scalloped plate, which is struck in thin iron metal and silvered, bears elements of the Massachusetts seal, minus the motto, and the legend "MASSACHUSETTS MILITIA." Its silver color assigns it to the infantry. The form of the specimen indicates that it was probably designed prior to 1839. In consideration of its over-all design and the use of the word "MILITIA," it was probably made as a stock pattern and sold to several different organizations. A plume holder, which has been resoldered to the reverse, appears to be of the same metal as the plate proper. It is pierced at the sides for attachment.
