350 PERMANENT CAPS FOR STACKS. 



girts, placed five feet eight inches above the sills, to 

 which height the box part of the structure is boarded. 

 The posts above the box are perforated with holes, one 

 foot apart, for the insertion of pins, to sustain the cap 

 or cover. This (in form of a pyramid) should be made 

 as light as possible, so that it may be readily raised by 

 placing the shoulder under the corner. The frame of 

 three by four joists must be large enough to fall outside 

 the posts and admit of some play. The rafters are 

 small joists, nine feet in length, the feet resting upon 

 short pieces of joist, placed across the corners of the 

 frame, thereby forming openings for the posts to pass. 

 The tops of the rafters are nailed together over the 

 centre of the frame. Girts should be placed half-way 

 from the eaves to the point of the roof, to nail covering 

 boards to. These should be good half-inch stuff, arid 

 run from the eaves to the rafters. The tops of the posts 

 should be kept from spreading by stay lathing them. 

 A hay-cap of the dimensions given will hold five tons 

 of hay. The cost I do not know, as this was on the 

 place at the time of my coming on to it."
