MINERAL INDUSTRIES LIME AND LIMESTONE. 37 



Florida Lime Company, Ocala, Florida. 

 Live Oak Limestone Company, Live Oak, Florida. 

 Marion Lime Company, Ocala, Florida. 

 Standard Lime Company, Kendrick, Florida. 



In addition to these, the Virginia-Florida Lime Company, and 

 the Blowers Lime and Phosphate Company, organized during 19 13, 

 were expected to begin operations during 19 14. 



The following account of the uses of lime, together with com- 

 ments on hydrated lime, is taken from an article on Lime by Ernest 

 F. Burchard in Mineral Lidustry for the Calendar year 1911, pt. 11, 

 pp. 649-652, 1912. 



USES OF LIME. 



Few mineral products have so wide a variety of uses as lime. Nearly 

 half the lime manufactured in the United States is used as a structural 

 material, and the remainder, amounting to about 1,750,000 tons, valued at 

 about $5,500,000, is consumed in chemical uses. The principal uses which 

 lime has in building operations are in lime mortars and plasters, in gaging 

 Portland cement mortars, concrete, and gypsum plasters, and as a white- 

 wash. Both quick and hydrated lime are used in building operations. 



The chemical uses of lime are much more varied than the uses of lime 

 in building. A number of the industries that are large users of lime are 

 listed below, together with the special purposes served by lime in each industry 

 and the kind of lime most suitable to such purposes.
