For outdoor work in winter the Canteen Service is provided with a gray whipcord overcoat and a close fitting gray cloth cap of the Royal Flying Corps type, the prescribed insignia being worn on the cuffs of the coat and on the front of the cap, as shown in the illustration. In summer a plain dark blue or black sailor hat with the insignia on the front of the band is worn either with or without the veil. The special insignia for the Canteen Workers is necessary at all times in order that the wearers may be quickly recognized by commanders of troop trains and camp organizations. BUREAU OF INFORMATION AND CLERICAL SERVICE UNIFORM.—This uniform consists of an apron of the same pattern as that for the workroom uniform of gray material and a gray veil. White collar and cuffs and the red cross on the apron and veil are worn with this uniform as shown by the illustration. UNIFORMS FOR USHERS AND OTHERS.—Ushers and other active personnel of the Red Cross, such as those engaged in membership campaigns, are allowed to wear a white badge on which is a red cross or they may wear a white sash with a red cross on the front. NURSES’ UNIFORMS.—The uniforms for female nurses in the Red Cross hospitals are similar to those worn by such nurses in the Army and Navy, but the nurses in the base hospitals and other military hospitals in France are required to wear uniforms of gray material.

S. Army and Navy camps and stations at home and abroad for the benefit of the enlisted men. At these stations everything practicable is done for the comfort and entertainment of the soldiers, sailors and marines who may be in the vicinity; lectures, music and moving pictures are provided, books, magazines and papers are furnished and facilities for writing letters are supplied. These Y. M. C. A. stations, or “huts” as they are frequently styled, are conducted by war workers detailed by the Association. In order that these war workers may be readily recognized at all times by officers and enlisted men a distinctive uniform has been authorized for them. This uniform is made of forestry-green cloth and consists of a sack coat, breeches, tan leather shoes, tan leather leggings, cap or field hat, flannel shirt, four-in-hand tie, and an overcoat.
