BULLETIN No. 143 



[February, 



The objection is frequently raised that a round barn is difficult 

 to light. This difficulty is entirely overcome in a barn 90 feet or 

 less in diameter, if a sufficient number of properly spaced windows 

 are used. See Figs. 4 and 30. With the same number of win- 

 dows, the light is more evenly distributed in a round barn and the 

 sun can shine directly into some portion at all hours of the day 

 during the winter. 



The objection has been raised that rectangular objects cannot 

 be placed in a circle without a waste of space, but this does not 

 apply to a dairy barn, as the storage of hay and grain depends upon 

 cubical content, alone, and silos should always be circular, no mat- 

 ter where built. Cows, when lying down, are decidedly wedge-

shaped, requiring much less space in front than behind. The ob- 

 jection may be raised, with round barns large enough for two rows 

 of cows, that the row headed out does not use the space as eco- 

 nomically as in the rectangular form, because a cow needs more 

 width at the rear of the platform than at the manger. Where 

 there are two rows of cows, the inner row is usually headed out, 

 and as only about one-third of the cows are in this row, this loss 

 of space is counterbalanced by the large number of cows in the 

 outer circle using the space more economically than they do in the 

 rectangular barn. 



Box stalls cannot be as conveniently arranged, but in a one-row 

 barn, gates hung on the outside and swung around to the manger, 

 form stalls for cows at freshening time, and in a barn with two 

 rows, box stalls can be arranged in the inner circle.
