The chin strap for all commissioned officers except chaplains is of black leather covered with gold lace braid one-half inch wide; for chaplains it is made of lustrous black mohair, as shown by figure 8. The chin strap for warrant officers’ caps is one-quarter of an inch in width, figure 10. The cap device embroidered on the center and front of the caps of all commissioned officers consists of a silver shield emblazoned paleways of thirteen pieces, with chief strewn with stars, surmounted by a silver spread eagle, the whole placed upon two crossed foul anchors in gold, as shown by the illustration. The cap device for warrant officers’ caps consists of the two crossed foul anchors in gold, as shown by figure 10. The blue cap for all commissioned officers below the rank of commander has a plain black patent leather visor, figure 9. The white caps for all officers are similar in shape to the blue caps, the band, cap devices, chin straps and visor decorations for the different corps and ranks being the same as for the blue caps of the same officers, figure 2. The cap for Warrant officers is the same as that for commissioned officers except that the device worn on the front consists of two gold foul anchors crossed and the chin strap of gold braid is but one-quarter of an inch wide, figure 10. INSIGNIA OF RANK AND CORPS The rank of officers of the Navy is indicated in four ways: first, by stripes upon the sleeves of the special full dress coat, frock coat, evening dress coat, blue service coat and overcoat; second, by rank insignia on each side of the front opening of the collar of the blue service coat; third, by stripes upon the shoulder marks (or straps) worn on the white service coat, the mess jacket and the overcoat; and fourth, by rank insignia on the upper surface of the epaulets worn with special full dress, full dress and evening dress. These stripes indicating rank encircle the sleeves, the lower one being two inches above the edge of the sleeve and parallel to it; on all blue coats except the overcoat they are of gold lace braid, except for chaplains who wear black braid stripes; and on the overcoats of all commissioned officers they are of black mohair braid.
