ANALYSES OF THE PATAPSCO GUANO COM- 

 PANY'S AMMONIATED SOLUBLE PHOSPHATE! 



Percentage, or amount contained in 100. 



From the mean of the above analyses, we 

 deduce the following amounts, contained in a 

 ton, or 2000 Ibs., together with the value of a 

 ton to the farmer : 



300-40 Ibs. Water.. ,. ( 



19-00 " Actual Ammonia @ 



31-20 " Nitrogen in organic matter. @ 



12-80 " Potash @ 



166*40 " Soluble Phosphoric Acid. .. @ 



132-60 " Insoluble " " , , . Cd>

Total value as fertilizer $31.25 



Value of bags (say) 2.00 



Total value to farmer , $33.25 



The above phosphate is sold at $55 per ton, 

 involving a loss of $21.75, or nearly 66 per cent, 

 to the fariher on every ton he purchases ; or, in 

 other words, he pays for it nearly 1* times as 

 much as it is worth.
