R. W. Thatcher." of the Nebraska Station, analyzed a luimher of 

 samples of ditl'erent foi'a<i'e crops cut at an inter\ al of three weeks, to 

 stud\' the ell'ect of the time of cutting- upon composition. 



In connection with an investij^ation of the feedinjjf value of hran, 

 W. Frear and \\ . A. Hutchison'' studied the composition of hran 

 from winter and sprint^ wheat. 



L. 11. Men-ill'' investij^ated the determined and calcuhit<'d heat of 

 com])ustion of feediuo- stufll's and the feces from sheep fed these 

 materials. As an illustration of the discrepancies observed in the case 

 of a number of samples of wheat and various millinc^ products, the 

 ditference ))etw'een the determination and the calculated fuel value 

 ranoed from 0.02«) to 0.-180 calorics, or nearly 10 per cent of the total 

 determined quantity. The variations, it is said, were intimate]}- con- 

 nected with the amount of crude tiber present. 



In a discussion of feeding farm animals M. E. eJaH'a and L. Ander- 

 son'^ devoted considerable attention to the feeding value of fruits, 

 summarizing a large amount of analytical data on this subject, most 

 of which was derived from station analyses. 



At the New Hampshire Station F. W. Morse" carried on a special 

 study of corn silage with reference to the amount of acidity developed 

 b}' ditierent varieties of corn preserved for different lengths of time. 



Extensive microscopical studies of the anatomical structure of the 

 seed of a number of cultural varieties of sorghum were carried on by 

 A. L. Winton./ 



The same author f'' reported similar studies of wdieat screenings. 



At the New Jersey Stations L. A. Voorhees and J. P. Street'* studied 

 the losses in the fat of corn meal due to the action of molds. On the 

 l)asis of a large number of analyses the fat in normal corn meal was 

 found to average in amount 47 per cent as much as the protein. Sam- 

 ples which showed under the microscope the presence of PenicUllxnn 

 glaucum had lost from 4.2 to 67.7 per cent of the fat w^hich should
