pods of the locust ; flax-seed ; the roots of grass, well washed ; the bark of trees ; and, finally, 

 even dry wood, cut into shavings. 



Eunning water is given in j^reference to stagnant. Bad water may be purified by charcoal, 

 hydrochloric, or acetic acids. If the water contains leeches, or other similar things, the horses 

 must drink with the nose-bag on. 



The water given to the horses ought to be, as nearly as possible^ of the same temperature as 

 the air ; therefore, in summer it may sometimes be necessary to expose it to the sun, while in 

 winter it should be given immediately after being drawn. 



STABLES. 



The following are the regulations and arrangements of stables : 



As far as possible, the horses of the same squadron should be placed in the same buildings 

 divided by partition walls or staircases into stables of equal capacity. 



When windows can be arranged in both long walls, place the horses head to head, separating 

 the two rows of stalls by a longitudinal partition, which should not be more than 1' higher than 

 the to2> of the hay rack, between the pillars which support the roof. 



The interior width of a stable, for 1 row of stalls, is 20'; for 2 rows, it is 40', when they are 

 head to head ; 34' 8", when they are tail to tail ; height of ceiling, 16' 8". 



Doors should be pierced in the gable ends, and in the transverse partition walls, to secure a 

 longitudinal ventilation during the absence of the horses. 



The doors for ordinary use should be pierced in the long walls ; width, 6' 8"; height, at least 

 8' 8". 



There should be a window, with an area of about 16 square feet, for every 3 stalls ; the sill 

 10' above the floor ; the sash revolving around a horizontal axis at the bottom, and opening 

 by the simplest mechanism ; wooden shutters to be jirovided, if necessary. 



The recesses for the windows should extend to the floor, and be provided with hooks or racks 

 for suspending the horse equipments ; in these recesses openings 3' 4" X 2' 4" should be made 

 through the wall, for throwing out the litter. 



If necessary, ventilators may be cut through the roof in the middle of the passage ways 

 behind the stalls ; ventilators near the floor should be employed only in cases of absolute 

 necessity. 



The floor ought to be of hard stones, laid on a firm foundation, and the joints filled with 

 hydraulic mortar, cement, or asphalt ; slope of floor of stall from two to three-tenths of an inch 

 in ten inches. 



Mangers of wood, stone, or cast iron, placed on a mass of masonry, the front surface of which, 

 as well as that of the manger, has a reversed slope of f . 



The wooden mangers are divided by partitions; those of stone or iron are hollowed out to 

 the length of 2' for each horse, being solid between the hollows; depth 8", width at top 1', at 

 bottom 9". 6; top of manger 3' 8" above the floor. 



The hay racks of wood and continuous, 3' 4" high, and placed 5' 4" above the floor. The 

 bars round and capable of turning in their sockets, each bar 1".2 in diameter, and placed 4" apart ; 

 racks of iron may be authorized. 



The system of securing the horse consists of: 1st, a bar of round iron bent at both ends, 

 placed up and down, parallel to the face of the manger, the upper end secured to the manger.
