must use very lieavy wire and fasten the eye bolts in such a manner that there 

 will be a minimum of stress. The eye bolts as shown in figures 22 and 23 

 should be placed nearer the ridge than shown in order to be servlceably suc- 

 cessful. 



Ordinarily when it is quite windy, this type of door hinged at top is best 

 kept tightly closed, otherwise the wind if strong will lift it off from its hingeg. 

 The use of as many as three hinges, strongly reinforced with battens on the 

 under side of the door, is quite desirable inasmuch as they will insure greater 

 strength and rigidity. 



THE TEPEE HOUSE. 



In building the Tepee (see figures 27. 28, 29, 30 and 31) we have economized 

 in tlie material used, and at the same time have constructed a most rigid and 

 substantial house. The angularity of the frame is such as to materially stiffen 

 the structure. It is quite questionable, however, if the saving of material will 

 compensate for the extra labor involved in building. The admission of sun- 

 light is not provided in the Tepee as presented, although side roof doors, pre- 

 ferably on the east when the house faces the south, may be easily provided. 



The use of fenders on three sides of the house is obviated in that the sloping 

 roof naturally protects the litter ; fenders will need be constructed therefore 

 only at the entrance and on either side of the door. 



Ventilation is provided through openings near the ridge both at the front 

 and rear ends.

This may be extended to gables by hinging side doors lower. 



Sliding is preferable to top hinged entrance door. Make 



doorway higher for mature swine.
