the manure and feed carriers. All 

 of this is outside of a central space 

 for a silo 20 feet in diameter and 71 

 feet high, with a capacity for 620 

 tons of silage, and in the mow there 

 would still be an excess, above the 

 capacity of the rectangular barn, of 

 33,000 cubic feet, which would hold 

 66 tons of hay, or as much as the en- 

 tire mow of a barn 32 x 36 feet with 

 20 foot posts. 



The square feet of floor space in 

 the round bam 90 feet in diameter 

 and rectangular barn 36 x 176% feet 

 are the same, but the cubical content 

 of the former is more than that of the 

 latter. The increase In the lumber 

 bill is 23 per cent, in the plank frame 

 and 53 per cent, in the mortise 

 frame barn. The round bam 90 feet 

 in diameter contains 283 and the 

 rectangular barn 426 lineal feet of 

 wall. The rectangular barn has, 

 therefore, 50 per cent, more lineal 

 feet of outside barn wall, requiring 

 a proportional increase in both paint 

 and foundation. 



The smaller surface on the outside 

 wall of the round barn requires less 

 paint and makes a proportional sav- 

 ing in keeping the round barn painted 

 in after years. 



Conclusions. 



The advantages of the round barn 

 are convenience, strength and cheap- 

 ness. 



The round barn is more convenient, 

 because of the unobstructed mow, 

 which reduces the labor required in 



mowing hay, and because of the 

 greater care and fewer steps with 

 which the feed can be gotten to the 

 cows, owing to the central location 

 of the supply. 



The circular construction is the 

 strongest because advantage is taken 

 of the lineal strength of the lumber. 

 All. exposed surfaces are circular, and 

 withstand greater wind pressure, as 

 the wind can get no direct hold, as on 

 the sides or gable ends of a rect- 

 angular barn. 



In round numbers, rectangular 

 barns require, according to their con- 

 struction, from 34 to 58 per cent, 

 more in cost of material than round 

 barns with the same floor area and 

 built of the same grade of material. 



Roofing. 



Shingles as roof covering are used 

 far more than any other type for 

 residences, farm buildings, sheds, etc. 

 The best shingles are made from cy- 

 press, redwood, or cedar, in the order 

 given. Cypress shingles are usually 

 18 inches long and are supi>osed to be 

 7-16 of an inch thick at the butt, while 

 other kinds are but 16 Inches long 

 and about 5-16 of an inch thick at the 

 hutt. The width of shingles varies 

 fram 2 1-.2 to 14 and even 16 inches. 

 They are sold in bundles, usually four 

 to a thousand, a "thousand" meaning 

 the equivalent of 1,000 shingles 4 

 inches wide. When shingles are to 

 be used for special designs, they are 

 sawed to a uniform width, either 4,
