A comparison of the above analyses shows that the sample sent 

 on from Boston does not represent fairly the quality of our current 

 articles of lime-kiln ashes. Good lime-kihi ashes owe their agricul- 

 tural value mainly to the lime they contain. The amount of potash 

 and phosphoric acid found present is in many instances but little more 

 than many kinds of good limestone contain. The wood ashes form 

 an insignificant part in the majority of samples of lime-kiln ashes. 

 A more liberal use of lime-kiln ashes and articles of a similar charac- 

 ter deserves encouragement in connection with the cultivation of 

 clover-like crops. Dealers in refuse lime from lime kilns will 

 increase their sales by advertising more liberally their goods during 

 autumn and early spring. ^
