44 BULLETIN No. 143 [February, 



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 unob- 

 structed 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 tlie 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.
