3. If a belt is too short it gives more trouble in running than it 

 would do if long enough. If much power is to be trans- 

 mitted the distance between the centres of the driving and 

 following pulleys should not be less than five times the 

 diameter of the larger pulley, and may be as much as 

 30 feet. 

 The cow byre provides accommodation for thirty-two cows. Part 

 of the stock shed may be partitioned off to form calf pens. The stock 

 shed is of wood-and-iron construction. The bull-boxes are provided 

 with separate exercise yards. The wall between the bull-boxes and the 

 bull-box feeding passage is a dwarf wall, so that food can easily be 

 thrown over it into the mangers. Liquid manure from the cow-byre 

 discharges into the sumps SS which are connected, by a 6-inch stone- 

 ware drain pipe, with the liquid manure tank (not shown). 



The stable contains stalls for four horses, and has a harness-room 

 adjoining. The loose box for horses is arranged in such a way that, 

 by erecting a temporary stall division, it can when desired be converted 

 into a stable containing two stalls. For this purpose the mangers are 

 constructed like those in the main stable. Drainage from the horse 

 loose-box and stable takes place into the sump shown, which must be 

 emptied at intervals by baling. This sump may, however, be connected 

 to the pipe which carries the cow-byre drainage to the liquid manure 

 tank. 



The sick boxes are isolated at the end of the wing. The party wall 

 separating them from the horse loose-box should extend upwards right 

 to the iron roof-covering, so as to completely isolate them. 



The piggery, implement shed, Cape-cart shed, and workshop are 

 all wood-and-iron buildings. The boiler-room, adjoining the piggery, 

 is of brick ; in it hot food can be prepared for the pigs. Each pig- 

 house is provided with an exercise yard. 



The buildings are arranged, so far as possible, to form the sides of 

 two yards, viz. the main yard and the stock yard. Each of these two 

 yards is provided with a drinking trough, that in the stock yard being 

 a circular one constructed of reinforced concrete. Each yard has two 

 gates, those of the main yard being 14-foot gates so that a waggon and 

 span of oxen can be driven easily through the yard. 



It will be noticed from the elevation drawings that the party wall 

 between the bull-boxes and the feed-room passes right through the roof-
