_The overcoat_ for bandsmen is of sky-blue cloth, double-breasted, buttoning to the neck with two rows of gilt navy buttons, lined with red flannel, falling collar five inches deep, cut to reach about six inches below the knee, and provided with a circular cape of the same color. The rank and special duty (or “rating” as it is styled in the navy) of the petty officers of the first, second and third classes, as given in the table on page 38, is shown by a “rating badge” which is worn on the right sleeve between the elbow and the shoulder by petty officers of the Seaman Branch and in the corresponding position on the left sleeve by all other petty officers. The rating badge consists of a spread eagle above a “specialty mark” showing the duty and a chevron showing the “class” or rank of the wearer. These badges are three and one-quarter inches broad. The chevrons are made of stripes of cloth three-eighths of an inch wide, placed one-quarter of an inch apart as shown in the illustrations. A peculiarity of the navy chevrons is that they are worn with the apex of the angle formed by the two bars of each stripe pointing down instead of up as in the army and marine corps. The specialty marks are placed in the center of the angle formed by the upper stripe of the chevron and the spread eagle is placed just above the specialty mark. For use on blue clothing the chevrons are made of scarlet cloth and the eagle and specialty marks are embroidered in white; while for white clothing the chevrons are of blue cloth and the specialty marks and eagle are embroidered in blue. For petty officers holding three consecutive good-conduct badges (namely, the good-conduct medal and two bars, representing three full enlistments served with efficiency and good conduct) the chevrons are made of gold lace braid and the eagle and specialty marks are embroidered in silver. The specialty marks indicating the different ranks or “ratings” are, as shown in the illustrations, as follows: NUMBER OF FIGURE IN ILLUSTRATION. RANK OR “RATING.” 1. Master-at-arms. 2. Boatswain’s mate, or coxswain. 3. Quartermaster. 4. Blacksmith, or shipfitter. 5. Sailmaker’s mate. 6. Printer. 7. Carpenter’s mate, plumber and fitter, painter. 8. Turret captain. 9.
