of linseed meal; and for 3020 pounds of oat straw used for 

 bedding. It is understood that the sheep were kept confined in 

 the stables during the entire time. 



Eight different analyses were made of the manure, and the Ohio 

 Station computes that, of the total plant food contained in the feed 

 and bedding, 64 per cent of the nitrogen, 79 per cent of the phos- 

 phorus, and 97 per cent of the potassium, were recovered in the 

 manure. 



Wood, of the University of Cambridge, England, reports an 

 experiment with four heifers to determine losses in making and 

 storing farm manure (Journal of Agricultural Science, April, 1907). 



The experimental feeding began on January 31, 1906, and ended 

 on April 25, 1906, a period of 84 days. During this time two of the 

 animals consumed 13,720 pounds of mangels (containing 1784
