723 appears to contain a large admixture of Cotton Seed Meal, 

 to which its greater content of nitrogen is due. 



Some tobacco growers believe that Castor Pomace has a par- 

 ticularly favorable effect on the quality of the tobacco leaf, which 

 cannot be produced by other nitrogenous manures, and therefore 

 prefer to pay a special price for nitrogen in this form. The Sta- 

 tion valuations, however, as is abundantly explained else^rhere, 

 do not and are not designed to indicate the agricultural value of 

 fertilizers, but represent the average market prices of their differ- 

 ent ingredients. 



Fowl Manure. 



A sample of this material, 684, sold by Horatio Lothrop, 

 Suffield, and sent by H. H. Austin, Suffield, has the following 

 composition : 



Nitrogen,. 3.25 



Insoluble in acid (sand and soiJ), 38.20 



Potash, 1.12 



Phosphoric acid, _ 2.83 



Estimated value per ton, ...^ $1 9.43 



Cost, $27.00 



The fowl manure was quite dry. It contained a considerable 

 quantity of feathers. In it nitrogen is valued at 20 cents, phos- 

 phoric acid at 9 cents, and potash at 6 cents.
