ANALYSES OF ERODES' SUPERPHOSPHATE. 

 Percentage, or amount contained in 100. 



From the mean of the above analyses, we de- 

 duce the following amounts contained in a ton, 

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

 the farmer : 



154-60 Ibs. Water @ $0.00 per Ib. $0.00 



Trace Nitrogen @ 0.15 " 0.00 



70-40 Ibs. Soluble Phos. Acid @ 0.12 " 8.80 



305-00 " Insoluble " " Cob 0.00 " 0.00 



Total value, as Superphosphate $8.80 



Yalue of bags (say) 2.00 



Total value to farmer $10.80 



The above phosphate is sold at $50 per ton, 

 involving a loss of $39.20, or 363 per cent, to 

 the farmer on every ton he purchases ; or, in 

 other words, he pays for it 4f times as much as 

 it is worth.
