As the terms used above, "freight ships" and "transports," will frequently recur in this chapter, it is necessary to give an explanation of their meaning and of the distinction between them. Troops are carried either in a transport or a freight ship. A transport is a vessel wholly taken up by the Government on a time charter. A freight ship is one in which the whole or a portion of the accommodation is engaged at a rate per head, or for a lump sum for a definite voyage. For a single voyage, freight, when obtainable, is generally cheaper. But owners will not always divert their ships under other than a time charter, and it is necessary that the bulk of the engagements for the conveyance of troops should be on time charter in order to secure control over the ships. Transports, when continuously employed and utilised both ways, are cheaper than freight ships. Under the transport charter the vessel, though engaged for a named period certain, is at the disposal of the Admiralty so long as the Government choose to retain her, except when it is expressly stipulated otherwise. [Sidenote: Govt. sea transport.] The method by which the Government carries out the sea transport of the Army is as follows: The Board of Admiralty, as agents for, and on the requisition of, the Secretary of State for War, undertakes all this work, except coastwise conveyance in the United Kingdom. [Sidenote: Office method.] Since 1st April, 1888, Army Sea Transport has been always charged to Army instead of to Navy Votes; but the control of the Admiralty over the Transport service remains unimpaired. The Admiralty has always held that the work can be efficiently and satisfactorily carried out only by an Admiralty department, in connection with similar work for the Navy. For convenience sake the Director of Transports is placed in direct communication with the War Office as to all ordinary matters. An officer of the Quartermaster-General's department visits the Transport department frequently in peace time, and in war time he is placed at the Admiralty to assist the Director of Transports in military questions. All claims chargeable to Army Votes, after examination in the Transport department, receive, before they are passed to the War Office for payment, the concurrence of Army examiners, who visit the Admiralty daily. The Director of Transports is responsible for the whole work; administration, claims and accounts, custody of Army Transport stores, such as troop-bedding, horse-gear, etc., etc. The system by which one department does the work, while another provides for the cost, seems somewhat anomalous. But the experience of the Boer War, in which it was put to a test of some magnitude, has conclusively proved that it works well. That experience has, moreover, fully shown the necessity of the Sea Transport service remaining as it always has been, under the control of the Admiralty. [Sidenote: Transport department at work.]
