ALABAMA MICA DEPOSITS 107 



In every notable instance of important kaolin deposits, 

 water supplies, amply sufficient for flotation, are present 

 and closely adjacent. 



Throughout the mica field, timber for mine, plant con- 

 struction, and fuel purposes, is generally present in suf- 

 ficient amount for a considerable period of operation, and 

 as previously stated, hydro-electric power, either al- 

 ready on the transmission lines, or in the making is now 

 and will be in larger amounts subsequently available as a 

 permanent future basis of economic power for plant and 

 mine operation, by reason of its frequent proximity, and 

 the fair and favorable ruling rates for contract power 

 service. 



In view of these facts, such analyses and partial tests 

 as have been at various times made, become of sufficient 

 interest to be here stated as possibly justifying the com- 

 plete, competent, experienced, and thorough study of 

 Alabama mica-kaolins, which it is confidently hoped may 

 soon be made. 



Attention was first called to the value and possibilities 

 of Alabama porcelain clays by Michael Tuomey, State 

 geologist, in the second report made for the Alabama 

 Geological survey in 1855. 



Following the suggestions and opinions advanced by 

 Tuomey, the Alabama Kaolin Company, later on in 1888, 

 (acquiring large property holdings at and near Micaville, 

 including the above sections) submitted proper samples 

 of clay from that locality for testing to Mr. Henry Brunt, 

 manager of the Chesapeake pottery, Baltimore, for prac- 

 tical pottery test. 



Preliminary to these practical commercial tests the 

 following analyses were made of the Micaville kaolin.
