 half the value of ordinary poudrette. 



Beet Pulp. This residue, of the manufac- 

 ture of Beet sugar, is most generally used as 

 food for cattle. Fresh from the press, its con- 

 tent of nitrogen is 0.378 per ct. ; when dried 

 in the air, 1.14; in vacuo, 1.26. 



The macerated sliced beets, from the sugar 

 process of Mathieu, contain too little nitrogen 

 to pay the expense of their transportation. 



Tan. Leeched Tan, from the leather vats, 

 after being dried and treated with lime, to neu-

 a manure. 



Torteaux. The oleaginons grains, after the

 as torteaux. These residua contain nearly all 

 the nitrogenous matter contained in the plant, 

 and, being but slightly moist, form an excel- 

 lent manure, convenient and profitable for 

 transportation. 



The most used are the marcs of olives, cole- 

 seed, madia, flax-seed, arachis, all very rich
