1(33 BOARD OF AGRICULTURE. 



inch thick, and put them on double, nailing fully -with No. 12 nails ; 

 put up the upper portion of the frame in the same manner, and 

 complete the boarding of the walls before raising the roof Erect a 

 temporary staging on centre girts, on which to work in raising the 

 roof; give the roof a good elevation. Ours rises fifteen feet above 

 the walls at the apex ; the corner rafters 8 by 3 inches, of spruce ; 

 the others two inches thick. This form of roof, when well boarded 

 and nailed, is self-supporting ; n^ beams nor interi ;r posts are neces- 

 sary ; clapboard the walls ; shingle the roof^ painting as you lay the 

 shingles. A cheap paint may be had of pine oil and hydraulic 

 cement ; or Ohio clay, (Blake's patent,) or even Maine clay. 



A scaffold thirteen feet long is put over the floor, and twelve feet 

 above it. 



The small barn above described will store twenty tons of hay. We 

 find it convenient, and if it has faults or omissions, we have not, in 

 three years, had time to find them. 



We are satisfied that no other disposition of the same amount of 

 material will give so strong and spacious a structure. The frame is 

 simple and cheap. The covering, if put on as it should be, takes 

 much time. A considerable saving in labor may be made by cutting 

 the shingles to pattern for the corners at a shop with a burr saw and 

 side-table. A ventilator is left at the apex of the roof, and always 

 kept open. Good scaffold flooring can be made of plank sawed from 

 large elm trees, which are of but little worth for other purposes. 



This plan, though rather on the " Chicago balloon" order in its 

 details, is offered with much confidence. 



The committee will theorize so far as to present in outline a large 

 structure on the above plan.
