ment, being grouped round the three sides of a square with 

 the big covered yard in the centre. 



To the north-west is placed the barn range, a brick-built and 

 slated building, arranged for the concentration, preparation, 

 and easy distribution of fodder of all kinds. The planning and 

 arrangement of this building are practically normal, and call 

 for no particular comment save that the upper floor will be 

 constructed of fire-resisting materials with a grano paving- 

 finish. One of the distinguishing features of the plan is the 

 covered cartway connecting the main range with the covered 

 yard and stock sheds. The roof of this cartway, the stock 

 boxes, and covered yard will be constructed in creosoted timber 

 framing with felted roofs, as it is considered that these build- 

 ings thus constructed are more readily adaptable to meet chang- 

 ing conditions or the special needs of experimental work, as 

 well as being less costly to erect. 



The covered yard is, for the special purposes of experimental 

 feeding and recording, divided into 3 equal portions each 

 designed to accommodate 10 cows. 



Manners and standings for the 30 cows are placed imme- 

 diately abutting upon the covered cartway and in close proxi- 

 mity to the administrative range, thus allowing for the most 

 labour-saving means of attendance upon the animals. A post 

 and movable rail fence separates the standings from the 

 remainder of the covered yard. 



The covered yard is roofed by means of Belfast truss prin- 

 cipals at 12-foot centres with a clear span of 35 feet. The 

 containing fence on the south side is placed 14 feet beyond the 

 span of the roof, thus allowing some open yard area where 

 stock can obtain full advantage from the sun. The floor of the 

 yards will be of 6-in. rammed chalk. 



The boxes on the south side have been designed with the 

 intention of ultimate conversion to double cowstandings by 

 the addition of another bay to the main Belfast truss roof, 

 which is extended on tin's side to include the range of boxes. 

 On the opposite side, to the north, a low span-roof building 

 contains 2 boxes and a number of calf pens. 



Drainage from the standings and covered yard is collected 

 in a manure tank. 



Thus it will be seen that the general arrangement of the 

 buildings themselves is quite on traditional lines, save that 

 it is perhaps more usual to find a central range separatii..: 

 covered or open yards. Tn such a case, were conversion
