 -5. Light. 



' Special attention was paid to the lighting of this shed, as -undoubtedly the great 

 proportion of sheep troubles come from insufficient light, lack of fresh air, and poor 

 ventilation. All windows were hinged at the bottom and fastened at the top with a 

 short chain, thus allowing the window to drop open from the top and allow a free pass- 

 age of air through the building. The doors also were made 4 feet in width and were 

 so arranged that they can be open at all times except during very severe weather. No 

 ventilation system, aside from the windows and doors, was provided, since both 

 windows and doors are kept open at practically all times. 



4. Feed Passage. 



The feed passage across the ends of the pens was provided for the ease in feedii>g 

 of the forages and also, at one end, to provide room for keeping a limited amount of 

 grains in this building. A wood floor was provided for this passag?, both from a point 

 of cleanliness and economy of foodstuffs. 



5. Pens. 



The site of the building was chasen on account of its dryness and good facilities 

 for drainage. Earth floors, for the pens where straw bedding can be iised, are con- 

 sidered the best. The doors of pens into paddocks "were arranged to eliminate draughts. 

 These doors open to the south, and were made 4 feet in width in order to eliminate 

 the hipping of ewes or the crowding of lambs in the doorway. The sizes of pens were 

 based on the area required for various classes of stock according to the experience 

 with sheep on the Central Experimental Farm. These areas are as follows: For large 

 breeding ewes, 10 to 12 square feet of floor space; smaller breeding ewes, 8 to 10 square 

 feet; feeding and breeding lambs, 5 to 8 square feet. The four pens of this shed will 

 conveniently accommodate twenty-five to thirty feeding lambs each. 



6. Feed racl's. 



The accompanying diagrams of feed racks installed are self-explanatory. Three 

 different types of hay racks were installed for comparative purposes, type " A " rack 

 including the grain trough in bottom of rack, while the other two types of racks have 

 the grain trough in front of rack. All three types have given good satisfaction in the 

 limited time which they have been used. These and other types of racks and troughs 

 will be installed for comparative purposes, during the coming year.
