Guards should be detailed and so stationed on the train to preserve order both when in motion and during stoppages. The arrangement of the ordinary artillery-train will be:
1. Cars with material necessary for disembarking.
2. Horse-cars.
3. Baggage-cars, loaded with forage, harness, etc.
4. Cars for material.
5. Cars for officers and men.
The size of the train will vary, depending on grade, curvature, and speed.
TRANSPORTATION OF ARTILLERY-HORSES BY SEA.
Transports for horses should be especially prepared for the purpose; as a rule, the larger the vessel the better is she adapted for the conveyance of horses. Ventilation is of primary importance, the safety and condition of the horses mainly depending upon their having plenty of fresh air; large air-ports or scuttles are indispensable, and wind-sails down every hatch to each deck should be insisted upon. If time permits, fixed air-shafts should be provided for each deck. The ventilation of steamers may be assisted by using the donkey-engines for this purpose.
The stalls are preferably between-decks, never, if it can be avoided, in the hold; should horses be put on the spar-deck, nothing will be stowed on the stall-sheds. Stalls should be about 6½ feet long, 28 inches wide; tail-boards fastened to the rear posts, and padded as low as the hock; breast-boards and side-boards fitted in grooves about 4 feet from the floor, the first padded on the inner side and upper edge, the latter on both sides; the floors of the stalls set on blocks that the water may pass under them; four slats across each floor to give the horses foothold. Troughs should be made to hang with hooks, so as to be easily removed.
