seldom observed in less than four weeks, and they are 

 usually shown in the periods between the thirtieth and 

 fortieth day after the feeding of cotton-seed meal is begun. 

 Fermenting the meal seems to decrease this danger, as 

 probably does also the feeding of green or succulent food at 

 the same time. Cotton-seed meal is injurious to young 

 calves, and probably to most very young aniinals. 



LABORATORY EXERCISES 



From the tables on page 271 calculate for an acre producing 

 500 pounds of lint what would be the probable weight of 



(o) dry stems, or stalks ; 



(6) the number of pounds of nitrogen lost if the stalks, roots, 

 and burs of a crop of this size be burned, assuming that these 

 parts of the plant increase at the same rate as the yield of lint.
