The accompanying cut of a barn is given merely as an illustration of a convenient arrangement for a medium-sized dairy, and not as being adapted to all circumstances or situations. This barn is supposed to stand upon a side-hill or an inclined surface, where it is easy to have a cellar, if desired; and the cattle-room, as shown in the cut, is in the second story, or directly over the cellar, the bottom of which should be somewhat dished, or lower in the middle than around the outer sides, and carefully paved, or laid in cement. [Illustration: BARN FOR THIRTY-FOUR COWS AND THREE YOKE OF OXEN.] On the outside is represented an open shed, _m_, for carts and wagons to remain under cover, thirty feet by fifteen, while _l l l l l l_ are bins for vegetables, to be filled through scuttles from the floor of the story above, and surrounded by solid walls. The area of this whole floor equals one hundred feet by fifty-seven. _k_, is an open space, nearly on a level with the cow-chamber, through the door _p_. _s_, stairs to the third story and to the cellar, _d d d_, passage next to the walls, five feet wide, and nine inches above the dung-pit. _e e e_, dung-pit, two feet wide, and seven inches below the floor where the cattle stand. The manure drops from this pit into the cellar below, five feet from the walls, and quite around the cellar. _c c c_, plank floor for cows, four feet six inches long. _b b b_, stalls for three yoke of oxen, on a platform five feet six inches long, _n n_, calf-pens, which may also be used for cows in calving. _r r_, feeding-troughs for calves. The feeding-boxes are made in the form of trays, with partitions between them. Water comes in by a pipe, to cistern _a_. This cistern is regulated by a cock and ball, and the water flows by dotted lines, _o o o_, to the boxes; each box being connected by lead pipes well secured from frost, so that, if desired, each animal can be watered without leaving the stall, or water can be kept constantly before it. A scuttle, through which sweepings and refuse may be put into the cellar, is seen at _f_. _g_ is a bin receiving cut hay from the third story, or hay-room, _h h h h h h_, bins for grain-feed. _i_ is a tunnel to conduct manure or muck from the hay-floor to the cellar. _j j_, sliding-doors on wheels. The cows all face toward the open area in the centre. This cow-room may be furnished with a thermometer, clock, etc., and should always be well ventilated by sliding windows, which at the same time admit the light. The next cut is a transverse section of the same cow-room; _a_ being a walk behind the cows, five feet wide; _b_, dung-pit; _c_, cattle-stand; _d_, feeding-trough, with a bottom on a level with the platform where the cattle stand; _k_, open area, forty-three feet, by fifty-six.
