Results of Analysis. A sample of " Nitro Phosphated Fertilizer" 

 received from H. E. Pond, Esq., of Franklin, has been analyzed, with 

 the following results : 



o 



One hundred parts contain — 



Moisture, 13.30 



Organic matter, humas, &c., (dry,) ...... 34.40 



Bone Phosphate of Lime, ....... 12.80 



(Soluble Phosphate of Lime, 4y^.) 



Sulphuric Acid, ......... 4.40 



Sulphate of Lime, 19.80 



Salts of Potash and Soda, . . . . . . .11.10 



Sand, 4.20 



100. 



The organic matter yields 2 /^j per cent, of Ammonia. The salts con- 

 sist of 2^^ per cent. Nitrate of Potash; 4^^^ per cent. Nitrate of Soda, 

 and 4^^ per cent. Common Salt. Rain water will dissolve 4^^ per cent, 

 of the Bone Phosphate of Lime. 



I am surprised to find so many valuable ingredients in a fertilizer of 

 this kind. It will be an excellent addition for any soil, but is especially 

 adapted to tobacco raising.
