There is a growing tendency to incorporate more hulls in cottonseed 

 meal, as is clearly demonstrated in the gradual and consistent increase in 

 the fiber content of the meals collected during the last seventeen years. 

 The preceding average does not show the w^orst samples, as a number of 

 those collected during 1914 contained as high as 12 per cent, of fiber. 



Cottonseed meal has long been considered the most economical and 

 satisfactory protein concentrate that the New England dairy farmer

 gradual decrease in its quality must stop. 



Bartlett has demonstrated in a very striking manner the wide difference 

 in the feecUng value of cottonseed meal containing different proportions 

 of fiber or huUs by actual digestion tests with sheep, as foUow's: ^ —
