INSPECTION OF LIME PRODUCTS USED IN 

 AGRICULTURE 



By H. D. Haskins, L. S. Walker and R. W. Swift 



Twenty-nine samples, representing seventeen brands of manu- 

 factured lime, and seventeen samples, representing nine brands 

 of raw ground limestone, is the record on lime for the 1921 ferti- 

 lizer control. Of this total of twenty-six brands as represented 

 by samples taken in the field, all equaled or exceeded the guaran- 

 tee under which they were sold. Two of the seventeen samples 

 of ground limestone, however, were not as finely ground as could 

 be desired. Other than this the 1921 lime trade in Massachusetts 

 seemed to be on a sound basis in as far as quality of the product 

 is concerned. This bulletin reports the results of analyses of the 

 samples drawn.
