MANNER OF FRAMING THE MIDDLE BENTS OF A LARGE BARN. 



48. The importance 

 of having large build

 a manner that the sides 

 will not be thrust late 

 rally by the rafters, has 

 already been alluded 

 to in par. 17. Fig. 7 

 represents a style of

 tight instead of being pinned. The braces a a, at the foot of the 

 purline posts, should be nearly as large as the purline posts ; and 

 should face on the opposite sides from the girts. Should the 

 purline posts be not less than twelve feet long, a beam might be 

 framed in ; and there would be sufficient room to pitch with a 

 horse pitch-fork, both under and over the purline beam. If the 

 doors are so arranged that teams are driven length ways of the 

 barn or across it, the framing will be nearly the same in both 

 cases. Very large builomgs may be framed in this manner ; and 

 if the work is well performed the sides will not spread one-fourth
