Just for a few minutes I want to explain to you the planning 

 of the modern sanitary barn. It should be situated so as to get 

 the sunlight in the forenoon and on the other side in the after- 

 noon. In building a new barn, 36 feet in width is the most 

 economical width to use. It affords plenty of space for the dif- 

 ferent features of the barn and is not too large. In that case you 

 would have 5 feet between the mangers with stanchions 2 feet 9 

 inches at the top and a pillar there 4 inches in diameter, a stall 4 

 feet 8 inches in length, gutters 16 inches in breadth, depth of 

 gutter at this point 8 inches, and at the opposite point 5 inches, 

 meaning that the floor in the stall is about 3 inches higher than 

 it is in the alley. 



See Cut A. 



Another recommendation is to face the cows inward be- 

 cause if it is true that sunlight is the best destroyer of the bac- 

 teria in the barn you want the sunlight to strike the part that is 

 most likely to be affected, which is the gutters and rear end of 

 the cow. In addition to tlmt, brilliant sunlight if it strikes the 

 cattle squarely in the face, would be too dazzling. 



Illustration "A" also shows the arrangement of the floor 

 plan of the bam, the stalls and stanchions indicated, with feed 

 alley between, and the litter carrier back of the stalls. The pens 

 are shown and the silos in the end, with the space between the 

 silos and the barn used for the grain bins. 



See Cut B. 



The method of ventilating the barn is illustrated in this 

 case. There are flues in the wall here near the ground coming 

 up to within one foot of the ceiling of the stable. The arrows 

 here indicate the process of taking the air out. Flues opening 

 near the floor conduct the foul air up to the roof. These flues 

 should be made air-tight. No system of ventilation will work 

 successfully unless that is done. 



Another recommendation : All flues, and especially outgoing 

 flues should be made of two thicknesses of matched lumber with 

 building paper between. 



See Cut C. 



Galvanized iron is not good, the moisture taken out, on ac- 

 count of the cold, precipitates and sometimes actually closes up
