TRENCH UNIFORMS. Officers are also authorized to wear the so-called trench coat, with the insignia of rank on the shoulder. This may also be worn on the raincoat. Officers serving in the Zone of Advance will be issued all articles of the enlisted man's uniform and equipment they need; and, when their duty in the trenches is over, they will return all such articles. NEATNESS IN DRESS. In connection with these new regulations concerning clothing, it is strictly laid down that every effort must be made at all times by the officers and men of the A.E.F. to present a neat and soldierly appearance. When men are not actually engaged on field service, it is directed that uniforms will be pressed and brushed, and that belts, leggings, shoes, boots, and brasses will be cleaned and polished. Even when on active service, it is required that advantage be taken of every opportunity to clean uniforms and equipment. "No soldier," says the order, "will be permitted to leave his command on pass unless he presents a neat and soldierly appearance, which will be determined at an inspection by an officer." AMBULANCE VENTILATION. Ford ambulances in the service of the A.E.F. are to be bored with one inch auger holes at three-inch intervals in double rows through the wooden front just at the driver's back and immediately beneath the roof; in the tail-board, also, there will be fifteen holes. This is to secure proper ventilation, as deaths have been known to occur, in other Allied services, within the enclosed bodies of the ambulances which are equipped with exhaust gas heaters. Ambulance drivers are cautioned to investigate the condition of their passengers at five-minute intervals. TYPHOID PROPHYLAXIS. Any men in the A.E.F. who have not as yet taken typhoid prophylaxis will be required to do so in the near future; and, in all cases where it is shown that complete protective measures have not been taken, the surgeon will administer triple vaccine prophylaxis. RED CROSS SEARCHERS. One "searcher" of the American Red Cross may be attached to each statistical section of the Adjutant-General's department throughout the A.E.F. and in each hospital sub-section, except in field hospitals. Information as to casualties, etc., will be furnished freely to Red Cross searchers subject to the necessary restrictions as to what may be forwarded, and at what times. MORE RATIONS. The meat, coffee and sugar rations of troops engaged in work involving hard manual labor of eight hours or more a day will be increased 25 per cent. up to the end of March. This holds true in future from November to March, inclusive. RECKLESS DRIVING.
