ANALYSES OF BERGER & BUTZ'S EXCELSIOR 



SUPERPHOSPHATE OF LIME. 

 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. 



182-40 Ibs. Water @ $0.00 per Ib. $ 0.00 



28 80 " Nitrogen in organic matter @ 0.15 " 4.32 



104-20 " Soluble Phosphoric Acid. . @ 0.12 j- " 13.03 



165-60 " Insoluble Phosphoric Acid. @ 0.00 " 0.00 



Total value as fertilizer $17.35 



Value of bags (say) 2.00 



Total value to farmer $19.35 



The above phosphate is sold at $50 per ton, 

 involving a loss of $30.65, or nearly 159 per 

 cent, to the farmer, on every ton he purchases ; 

 or, in other words, he pays nearly 2| times as 

 much for it as it is worth.
