used for structural purposes to that used for chemical and agricultural 

 purposes will vary in the different states, and cannot be accurately 

 determined. Pennsylvania, Ohio, New York, and Michigan are prob-

TABLE 37. 

 LIME PRODUCTION OF THE UNITED STATES. 



An examination of Table 37 will show that during the year 1903 

 lime was burned in 44 states and territories. Only six political divisions 

 failed to appear as lime producers Delaware, Louisiana, Mississippi, 

 New Hampshire, North Dakota, and the District of Columbia. Of 

 these six the District of Columbia is known to contain no limestone, 

 while in Delaware the limestone outcrops are few and unimportant. 

 The only limestone occurring in North Dakota is too impure for most 

 purposes, being in fact a natural-cement rock. Louisiana contains a 

 few small areas of limestone. In New Hampshire, however, limestones 

 are much commoner; while in Mississippi several important limestone 

 areas occur but are not at present utilized. 



The rank of the various states in regard to value of lime produced 

 was, for the year 1903, as follows: 



(1) Pennsylvania, (2) Ohio, (3) Maine, (4) New York, (5) Missouri, 

 (6) Wisconsin, (7) Utah, (8) Illinois, (9) California, (10) Michigan,
