A picket-line is established in the immediate vicinity of the battery stable, the horses being tied to a hemp or wire rope or chain passed through the picket-posts. There should be shallow trenches behind the horses to carry off rain, the ground on which they stand having just enough slope to let the water run into the trenches, or there may be a single drain in the centre along the line of the picket-posts. Constant attention must be paid to maintaining the ground about the picket-line in good order. =Hut Stables.=--Rough sheds with clapboarded roofs are the best; with the litter and some wet earth good walls can soon be constructed around the shed; these walls should be vertical on the inside, but with a good slope toward the outside. Sheds made 30 feet wide can accommodate two rows of horses, their heads being turned toward one another. Plenty of openings must be left for doors by which to remove the horses quickly in case of fire, and drainage must be well attended to. The stalls, or standing-space, should be 5 feet wide and 9 feet long. An excellent shed can be made under the lee of a bank by erecting forked poles, placing connecting pieces, and laying thereon boards or poles and thatching. GENERAL RULES FOR STABLE MANAGEMENT. The stable sergeant takes immediate charge of the police and sanitary condition of the stable, picket-line, etc., and is the custodian of the forage and stable property generally. The stable is to be kept thoroughly policed, free from smells, and well whitewashed. There must be no accumulation of manure or foul litter inside, or near the doors or windows without. The feed-boxes are washed out frequently and kept perfectly clean. The ground about the picket-line is swept daily and all dung, etc., carried to the manure-heap. Except at night, when the horses are bedded down, no manure or urine is to remain in the stalls; the stable police remove it as fast as it accumulates. If practicable, all woodwork within reach of the horses and not protected with sheet iron or other metal is painted with thin gas-tar, to prevent its being gnawed; it should be thoroughly dried before putting horses near it. The same precaution must be followed with regard to troughs, picket-posts, and hemp picket-line. Smoking in stables or in their immediate vicinity is prohibited. One or more lamps will be hung in each stable, to burn during the night. The horses are stalled according to their positions in the battery, the teams nearest the door being led out first; their places at the picket-line will be in accordance with the same rule. The name of each horse, and that of his rider or driver, are placed over his stall. Clay is the best for earthen floors, as it packs well. Gravel or sandy earth is not suitable. Each man is held responsible for the removal of the earth and the levelling of the floor of his stall.
