ANALYSES OP WATSON & CLAKK'S SUPER- 

 PHOSPHATE. 



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 : 



255-60 Ibs. Water. @ $0.00 per Ib. $0.00 



4-40 " Actual Ammonia @ 0.25 " 1.10 



12-00 " Nitrogen in organic mat. @ 0.15 " 1.80 



111-80 Ibs. Soluble Phos. Acid @ 0.12J " 13.97 



144-00 " Insoluble u u . (ob 0.00 " 0.00 



Total value as Superphosphate $16.87 



Yalue of bags (say) 2.00 



Total value to farmer $18.87 



The above phosphate is sold at $45 per ton, 

 involving a loss of $26.13 ? or 138 per cent., to the 

 farmer on ever}^ ton he purchases. He pays for 

 it very nearly 2J times what it is worth.
