118 FEEDING ANIMALS. 



prevent this long wing from rocking or swaying by a strong 

 broadside wind, these bents with the high beams should 

 have a long, stiff brace, running from the foot of the post 

 on the side of the floor to the outside post, just under this 

 high beam. Such a long brace on each side will hold the 

 barn rigidly from rocking. And whilst speaking of braces, 

 let it be remembered that a brace is valuable just in 

 proportion to its length. The braces from the outside 

 posts up to the plates should have a four-foot run. 

 They will assist very much in sustaining any weight 

 upon the plates. It is not intended to have any purlins 

 in these wings to support the roof, even though they 

 be 60 feet wide. The brace on top of the beam, as de- 

 scribed on page 112, for the long barn, will have a run, on 

 beam from post, of 12 feet, running up the post just under 

 the plate, and fastened by bolt, as there described. This 

 will hold the plates absolutely rigid, and the roof will not 

 spread them. The rafters will be as there described, only 

 they should not be placed more than two feet apart, and 

 the collar-beams should be 1M x 5 inches, and placed six 

 feet below the ridge, with every other pair of rafters double 

 collar-beamed ; that is, with a collar-beam nailed upon each 

 side of the rafters. This will make a strong shingle roof. 

 The collar-beams will be some 20 feet long, and will be 

 about as good a support to the roof as purlin beams. The 

 collar-beams would be as high as the barn would be likely 

 to be filled, so that no room will be lost, and the barn will 

 be practically free from obstructions to pitching with a 

 horse-fork. 



In the bents, where the cross-beams are raised nearly to 

 the plates, there must be a beam framed into the posts on 

 each side of the floor, 13 feet above the sills, to correspond 

 with the other beams over the floor, upon which scaffold- 

 ing may be placed for using the room over the floor. It 

 remains only to be mentioned that the interior sills are
