56 THE CONNECTICUT AGKICULTUEAL 



The weight of the struck bushel of 543 is about 55 lbs,, its com- 

 mercial value is not far from that of an equal weight of slacked 

 oyster-shell or other cheap lime. The other samples must be 

 reckoned at about the same commercial value. Their agricultural 

 value must be estimated as that of lime, and not that of leached 

 ashes.

This is an excellent fertilizer. Reckoning its potash at 4^ cts., 

 and phosphoric acid at 6 cts., the sample has a value of $47.72 

 per ton. The analysis does not, however, fully establish the avail- 

 ability of these ingredients. Evidently some 12 per cent, of the 

 potash is present in the form of silicate insoluble in water, and a 

 considerable amount of pliosphoric acid is of uncertain solubility. 

 Mr. Balloch was unable to put any price on the ashes and they 

 do not appear to have come into market to any noteworthy e.vtent. 

 Should they do so the Station will give them further investiga- 

 tion.
