Grape Cake. The pressed residuum of 

 grapes contains a goodly quantity of nitrogen, 

 and being of gradual decomposition, is a very 

 durable manure for vines. Dried in the air, 

 il contains 1.71 to 1.S3 nitrogen; completely 

 dried, 3.31 to 3.56. 



Cider Cake. The residual apple cake, from 

 the cider press, being acid, must be neutralized 

 with lime, before being used as a manure, if 

 the soil for which it is intended is not itself 

 calcareous. By admixture with dung it be- 

 comes neutralized without manipulation. 



Starch Grains. The pulpy mass from the 

 Starch factories,differing slightly in value from 

 that of the potato, is still useful for the nutri- 

 tion of animals, but when the quantity produced 

 exceeds the demands for that purpose, they 

 may be advantageously employed as manure, 

 especially as their preservation is difficultly 

 effiscted. This pulpy matter contains seven- 

 tenths of its weight of water, and 0.526 per 

 ct. of Nitrogen ; when completely dry, the 

 Nitrogen amounts to 1.95. The scum and 

 sediment of the lees of the Starch factories 

 contain 0.005 Nitrogen, nearly equal to the 

 amount in moist farm-yard dung. Daily, the 

 proprietor of a Starch manufactory near Ver-
