 figs. 2). — The specifications of a wooden hillside barn erected at the 

 station at a cost of between $6,000 and i^7,000 are given in full and the 

 plans are briefly discussed. The main features of the barn are a hay 

 and grain barn facing north, back of which are box stalls with storage 

 space above, silos at the ends, and 2 wings with stalls for stock, 

 running north and south, and partly inclosing an open court. 



"The hay and grain barn, 40 by 100 ft. in size, faces the north, and loads may be 

 taken in at this side and on the second floor. By this means all grain, as corn, oats, 

 mill feed, etc., naay be conveyed to bins at the left, and run by chutes to the mixing 

 and feed room below. 



"Over these bins is a large space, in which hay or fodder may be kept. At the 

 right, on entering the driveway, is a sjiace 40 by 42 ft., and extending from 12 ft. 

 beloM' driveway to comb of roof 30 ft. above it. This can be conveniently divided 

 into 9 spaces for various kinds of hay, to be fed to classes of animals as desired. All 

 hay is miloaded from wagons by hay carrier. . . . While unloading, the wagon 

 stands on a set of five-ton hay scales, offering an easy opportunity for weighing all 

 hay and grain i^roducts. Close by the cribs is a corn mill, and the meal, as it is 

 ground, drops to the feed room below". . . . 



"Beneath the driveway will be placed a gasoline engine to run the machines men- 

 tioned, besides the silage cutters, etc. The walls of the engine room are to be of 

 metal, excejjt the back, which will be the foundation wall. . . . 



"At the eastern end of the lower floor is situated an office. . . . Next that is a 

 herdsman's room. ... In the rear of this room is an ai^artment set off for keeping 

 the supplies needed about the barn — shovels, forks, sacks, oil, rope, etc. 



"Leaving the hay barn downstairs, we step into a long feeding passage in front of 

 the box stalls. Of these there are 10, each 9 by 10 ft. in size, arranged with a small 

 door leading to the passage in front, and most of them with doors outward to the 

 open court. These are used for bulls, farrowing cows, and young calves. Above the 

 passage mentioned is a long room, 10 by 80 ft., entered by a door from the driveway 

 above, that will be u.sed for various purposes, mainly for the keeping of rough fod- 

 ders used in experiment work." 



Of the 2 wings opening out of the feeding passage the west is 

 arranged for 12 horses, 2-1 head of 3^oung heifers and bulls, and 1-0 

 steers; the east is arranged to accommodate 52 milch cows. Special 

 precautions were taken to provide an abundance of light and air in 

 these wings. 



"They are 10 ft. from the floor to the plate behind the cattle, 18 ft. 6 in. to the 

 plate over the animals' heads, and 23 ft. 6 in. to the comb of roof. . . . 



"The center over feeding floor runs up with vertical sides above the roof over the 

 cattle. By this means we get windows that swing on pins in the center of sash, that 

 may be opened for ventilation. By a series of cords that run through sash pulleys, 

 these windows may be partly or fully opened, and all on one side at once. These, 

 with the ventilators on the top of the wings, windows in rear of the animals, and the
