This is particularly the case where a man has been wounded in the abdomen, from which wound he may quickly develop peritonitis and reach the valley of the shadow of death in a few hours if prompt attention is not given. It is also done in cases of head or lung injuries, or in any wound causing uncontrollable hemorrhage. In any of these emergencies, after the M.O. in the line has given all immediately necessary attention, the patient is ticketed SERIOUS by him, and he is rushed with all speed to the A.D.S., perhaps at great personal risk to the stretcher bearers. Here he is quickly transferred to an ambulance which may have to rush him over heavily shelled roads, missing the main dressing station altogether, and taking him direct to the C.C.S. for his life-saving operation. After varying periods in the C.C.S. the patients are sent by ambulance trains, which run almost to their doors, to base hospitals at the rear. From here they are re-transferred to hospital centers in England and Scotland. So much for the methods used in caring for the wounded in the lines during stationary periods. The same principles and methods are employed during big advances, but of course on a larger and more thorough scale. All the arrangements are made during the weeks preceding a push; extra stretcher bearers are trained; the field ambulances increase their staffs, particularly just behind the firing lines, in order that the field may be cleared of wounded at the first lull in the fighting. The whole intricate system is so complete and so well arranged that hundreds of cases may be rushed through in a few hours, some of them being comfortably in bed in English hospitals the evening of the day on which they received their "Blighty."
