floor of flags set in mortar, with a considerable fall towards one 

 point, or sink for carrying off tlie urine. 



The barn is well ventilated by large Louvre ventilators placed 

 in the ridge of the roof. Fresh air is admitted, and particularly 

 about the cows' heads, by the following contrivance : Under 

 the feeding passage is a channel communicating with the 

 external air at two points — at the south end wall, and at the 

 open shed facing the stack-yard, and in which the root washer 

 is fixed. This underground air channel has several branches 

 rising to the surface of the feeding passage, and which are 

 covered with perforated pieces of metal. Fresh air rises 

 through these openings when the slide in the south end of the 

 house is lifted. 



At the rear of the barn is the manure yard. The site imme- 

 diately occupied with manure is 86 by 53 feet ; and between 

 the manure heap and the barn is the receptacle for liquid 

 manure. This consists of a large tank divided by a partition 

 into two compartments, each 40 feet long, 8 feet wide, and 9 

 feet high- to the spring of the arch. One compartment receives 

 the urine from stables, barn, calf-pens, and piggeries ; the other 

 receives the liquid from the urinals, water-closets, wash-rooms, 

 &c. 



The bottom and sides of this tank were built of brick, lined 

 with two coats of Portland cement ; and a strong brick arch 

 covers it. 



A wooden shed, roofed with felt, has been erected against the 

 east wall of the manure court to accommodate young stock. 

 The length of the stands (8 feet) is the same as in the large 

 barn already described. This shed is 63 feet long and 12i feet 

 wide. 



The piggeries are placed on the norih side of the manure 

 yard. There are six sties with a southern aspect, each 10 feet 

 6 inches by 7 feet, with yards 16 feet by 7 feet. Torr's patent 

 troughs are used. They are rather expensive ; but the princi- 

 ple, (which is a good one,) can be easily applied in the case of 

 ordinary troughs. 



Piggery No. 2, placed in the middle of the range, and at 

 right angles to the others, is arranged precisely like the calf- 

 pens. There is a central passage 5 feet wide, on each side of 

 which are eight pens or sties, each being 6 feet by 6 feet 9
