CHAPTER IX THE EXPEDITIONARY FORCE (_continued_) ADMINISTRATIVE SERVICES A description will now be given of the organization of the British Administrative Services designed for the Expeditionary Force of six Divisions with a Cavalry Division and two Mounted Brigades. At the head of each Administrative Service is a _Director_, who is the adviser of the C.-in-C. on technical matters connected with the Service he administers. He is responsible for providing for the requirements which his Service is designed to meet, subject to the instructions of that branch of the Staff to which the C.-in-C. has delegated his authority in this respect. A representative of each Director is allotted to the Staff of the L. of C. and of the Subordinate Commands, to whom he holds the same position as his Director does to the Staff of the C.-in-C. The Services are thus kept in close touch with the Staff, so as to conform readily to the movements and requirements of the Troops. The following is a list of the Directors, and shows the nature of the duty of the Administrative Service which each directs. Director of Army Signals: Service of inter-communication. Director of Army Medical Services: Care of the sick and wounded; sanitation. Director of Army Transport: Provision of transport. Director of Army Supplies: Provision of food, forage, fuel, and light. Director of Army Ordnance Services: Provision of ammunition, equipment, clothing, and stores. Director of Army Veterinary Service: Care of animals. Director of Army Remounts: Providing fresh horses. Director of Army Railways: Working of railways. Director of Army Works: Engineer works on the L. of C.
