en, but the material will be that of the officers' uniform. For
officers other than general officers, the stiffening at the edge of the
flap will be the same color as the arm of the service to which the
officer belongs, and will project far enough above the edge of the flap
to give the appearance of piping when the cap is worn with the flap up.
General officers will have caps with stiffening of the same color as the
cap cloth itself, with a strip of gold braid an eighth of an inch to a
quarter of an inch from the outside of the flap.

Except where the helmet is prescribed, officers actually commanding
troops will wear the Oversea cap. At other times the Oversea or the
service cap is optional.

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.

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-mi
