A certain amount of time (ten to twelve days) and money (£2,000 to £5,000, according to the kind of ship) is required to fit a vessel for carrying either troops or animals after she is empty of cargo. The vessel having been selected (sometimes even while she is still at sea), has to be surveyed in order to decide details of the work necessary, and also in order to obtain the Board of Trade's passenger certificate if she is to carry men. Troops and horses cannot be carried in ready-fitted accommodation. The space ordinarily devoted to cargo or cattle is appropriated, and the requisite accommodation built up. In the best cavalry ships, which are generally cattle ships adapted, saloon and cabin accommodation has to be increased. This is done at the owner's expense as part of the bargain. Height between decks is an important factor. Even more height is required for horses than for men. Ships otherwise good often have to be rejected for failure in this respect. Mounted troops always travel men and horses together. The men are for sanitary reasons placed on a deck below the horses. In such cases the horses are not, as a rule, carried on exposed decks. This is both for the sake of the horses and because the deck space is required for exercising the men. For remount and mule freight-ships the exposed decks are utilised, unless the nature of the voyage renders it undesirable. [Sidenote: Provision for horses.] Horses must be carried either on wooden or wood-sheathed decks, or on cemented decks, or on platforms over metal decks with the gangways cemented. For men, in all cases, the decks must be wood or wood-sheathed. As modern vessels, other than passenger ships, usually have steel decks, this becomes a considerable item in the time and cost of fitting. It is also frequently necessary to cut such extra side-lights as are essential for carrying men or horses. Extra lighting, ventilation and distilling apparatus, mess tables, stools, and provision for men's hammocks must all be obtained. Latrines have to be built, as well as a prison, a hospital, and the numerous store-rooms and issue-rooms that are required. Horse stalls have to be fitted, and sometimes even an extra deck has to be laid. A considerable number of horse stalls are kept at the Government depôts, and the contractors who work for the Government are bound to be ready to fit up a certain number of transports at short notice. For this war the stock of horse fittings in hand was only utilised to a small extent, as it had been decided, a short time before the war broke out, to adopt a longer stall (eight feet) without horse hammocks, instead of the existing six feet six inches stall with hammock. There is no doubt that the new fitting was a great improvement. [Sidenote: "Transports." Mode of fitting up.] [Sidenote: "Freight" ships. Different method.]
