Four strong men, used to the job, find it extremely hard work to carry a stretcher case along such a trench. They may repeatedly have to raise the stretcher well above their heads, almost at arm’s length, so as to clear the walls of the trench at an awkward turning. To overcome this difficulty a trolley stretcher, suspended from a mono-rail running above the trench almost at the surface level, is used in such trenches as permit of its passage. It saves an immense amount of tedious labour and much lessens the discomfort of wounded men. The Advanced Dressing-Station. Arrived at an advanced dressing-station, a patient can be immediately operated upon, if this be necessary to save life. Or his wound may be one of those which, though grave, are likely to do better for some delay before operation. Just whatever is necessary at the moment is done; the recognised precautions against the states technically known as shock and collapse are taken; and then the patient is sent on at once to a casualty clearing station, with its ampler space and larger equipment. Probably he will ultimately pass from the C.C.S. to a general, or stationary, hospital more remote from the Front, and perhaps to a hospital in England. The Eye Hospital. If a case presents any special difficulty it will be sent to a specially equipped ward or to a specialist hospital. A typical hospital of the kind is the Army Eye Hospital, near the coast, commanded by a London oculist of distinction. Part of its equipment is a magnet of great power, which begins to draw out of the eye any fragments of metal that are in it as soon as the patient enters the room. By combining the use of instruments with this extricatory power of the magnet the sight of many men with severe eye-wounds is saved; the hospital possesses a remarkable collection of jagged fragments and sharp splinters of metal thus cut and coaxed out of eyes. Or a man with a rather intractable fracture of the thigh may be sent to one of the special wards photographed here, where the limb, and his whole body, can be slung at any angle that is convenient. Ingenious Aids. In the British Hospital of St. John of Jerusalem, near the French coast, there was lying, throughout last winter, an Australian soldier whose life, in the opinion of the surgeons, had only just been saved by the perfection of a special kind of bed which someone had given to the hospital. The man had been deeply and very dangerously wounded in the back, in such a way that his wounds could not have been dressed in an ordinary bed without such changes of position as would themselves have been injurious. By an ingenious mechanism the special bed could be hoisted, tilted and inclined till it was in any desired plane and at any convenient height, and any portion of the patient’s body could be reached without turning him over. A Perfect Hospital.
