Composition of Mixed Milk (largely Grade Cows, All Breeds). 

 American and Foreign. 



Naturally, the larger the proportion of cows in a given area 

 producing thin milk, the nearer will the mixed milk in that 

 area approach 12 per cent, solids ; and the larger the propor- 

 tion of cows in a given area, producing thick or rich milk, the 

 nearer will the average of the mixed milk be to 13 per cent, or 

 more of solids.
