on the west ; the apartments to be separated by a close partition. 

 A portion of the roof near the eaves, and also of the front of 

 the sties and fold, is to be glazed to secure warmth from the 

 sun in winter. An arched vault is to be made on the north of 

 the sties, entered through the wall, in which the food of the 

 swine is to be kept and cooked. 



A steam-pipe is to be laid in the ground from the steam- 

 generator in the vault previously described, to the food-vault 

 for swine, by which the food is cooked. 



The dairy should be so located that the refuse of it will flow, 

 in pipes laid in the ground, to the vault for swine. 



The ridge of the roof of these two apartments is to be raised 

 above the bank-wall some five feet, and one-half of this space 

 arranged to be opened when required for cooking and venti- 

 lating. 



The fold is reached from the basement of the barn through 

 the wagon-house, and the hay is supplied to the fold by a shute 

 from the mow over the wagon-house. The sties and fold have 

 their respective yards extending down to the manure-house, and 

 the excrement from all the animals is to be mixed in it. All 

 the apartments for animals are to be supplied with air in winter 

 by an air-duct, laid beloiv frost in the ground, some 200 feet in 

 length. The duct is to ascend from the point where it receives 

 the air to where it discharges it, through the floor of the feeding- 

 passages in front of the animals. He claims that the air in the 

 duct will absorb heat from the earth, and as it becomes rarified, 

 will rise into the stable, &c., whence it is to be removed by ver- 

 tical shafts opening at the ceiling of the stable and extending 

 to the roof, where it escapes by a common, spacious egress 

 formed in the cupola on the crest of the roof. The air being 

 admitted at the floor in front of the animals, and escaping at 

 the ceiling behind them, places their heads in a direct line be- 

 tween the ingress and egress, and the excrement directly under 

 the latter, thus effectually providing for the most wholesome 

 and effectual change of the air, without a perceptible draft or 

 current. Mr. W. stated that several years' experience with this 

 mode of supplying air to stables had established the fact that 

 the air may be supplied to a stable otherwise close, above the 

 freezing point when the external temperature is eight degrees 

 below zero, and great economy and comfort secured.
