[Ill.u.s.tration: FIG. 42. ARRANGEMENT OF COW STABLE IN BARN NO. 6.]
The barn has been racked three times by the wind, replumbed and heavy iron rods put in to brace it, yet it is out of plumb at the present time.
CONCLUSIONS
In summing up the data given in this bulletin, it is obvious that the advantages of the round barn are convenience, strength, and cheapness.
The round barn is the more convenient, because of the un.o.bstructed mow, which reduces the labor required in mowing hay, and because of the greater ease 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 rectangular barn.
In round numbers, rectangular barns require, according to their construction, from 34 to 58 percent more in cost of material than round barns with the same floor area and built of the same grade of material.
