[Illustration: FIG. 5.--The McCormack-Brook Wheeled Stretcher Carriage. It consists of an under-carriage built up of two light wheels with steel spokes and rims with rubber tyres and ball bearings; on the axle are two light elliptic springs, to which is attached a transverse seat for the stretcher-carrier proper. This is securely bolted on to the seat, and consists of two pieces of hard wood, suitably worked, and forming an angle frame. On the bottom side the stretcher poles rest, and the sides of the L formed by the carrier proper prevent most effectually any jerking or turning of the stretcher when once it has been laid in the carrier. The carrier is about thirty inches long, but can be increased to any length desired. It has been found that this length is admirably suited for all purposes. To prevent the stretcher from any lateral or upward movement, two buttons with tightening screws are attached to the top of the carrier on each side. When the stretcher is laid on the carrier the screws are tightened and the stretcher is held rigid. Two iron supports are provided, one at each end and on opposite sides of the carrier. These are lowered when it is desired either to place the stretcher on the carriage or remove it therefrom, which can be effected in a second. The carriage meanwhile remains perfectly still. When the carriage is in motion the iron supports are turned up, and lie along the respective sides of the carrier, where each rests in a small clip. The great object of this stretcher carriage has been to obtain mobility, strength, and lightness combined with efficiency and a ready and easy means of transport for sick and wounded, no matter where a patient has to be transported from. The loaded stretcher and wheeled carriage can be readily handled by one man on good roads, and by two men in rough country. The springs prevent any jar being felt by the patient on the stretcher.] (_b_) For the longer journeys to the Field or Stationary hospitals, the service wagon and other transport vehicles came into use, particularly the South African ox-wagon.
