soil rather than build the soil up, especially when lime is used 

 alone and continuously without fertilizer on poor soil." If refer- 

 ence is made here to caustic lime only, we agree entirely with the con- 

 clusion ; but if the intention is to inchide unburned lime, the conclusion 

 is erroneous and misleading, because we have ample experimental evi- 

 dence to show that carbonate of lime has a direct tendency to build up 

 and not to exhaust the fertility of the soil. But the circular fails to 

 define the term "lime," which to the popular mind always means burned 

 lime, and thus the publication becomes doubly harmful — the reader does 

 not dare move either one way or the other for fear he will make a disas- 

 trous mistake. 



In. section 1, chapter 265, Public Laws of ISTorth Carolina, 1915, we 

 find "that only unburned lime shall be deemed lime for agricultural 

 purposes," thus defining by legislative enactment the form of lime best 

 suited for agricultural purposes. 



It seems that there has been an especial effort made to confuse the 

 farmer in the matter of purchasing lime for crop purposes by multiply- 

 ing the number of terms or names under which it is sold. While 

 there is no fertilizing ingredient of easier application or of simpler 

 composition than agricultural lime, still, when the farmer attempts to 

 make a purchase, he may be confronted by any one of the following 

 twenty-six different names and be hard put to it to know just which kind 

 to choose. The different names under which the farmer is likely to 

 find agricultural lime offered on the market are as follows : 



Air-slaked lime Quicklime 



Hydrated lime Builder's lime 



Rock lime Stone lime 



Prepared lime Sulphate of lime 



Caustic lime Land plaster 



Burned lime Water-slaked lime 



Barreled lime Unslaked lime 



CaCo3 lime Agricultural lime 



Unburned lime Marble 



Precipitated lime Calcium oxide 



Carbonate of lime Shell lime 



Marl-lime Gypsum 



But since there is but one form of lime suitable for general agricul- 

 tural purposes, namely, the carbonate form, the Legislature deemed it 

 best to suppress the above mischief-making list of terms and confine the 

 terms used to designate the carbonate form of lime to "limestone" and 

 "marl." On page 7 of Extension Circular, No. 24, however, Ave find 

 fifteen of these different names for lime, all of which, the circular says.
