200 Bulletin of Laboratories of Denis on University. [Voi. xii 



Systematic field-study of the ocher and manganese-deposits 

 of Georgia was begun by me while I was a member of the 

 State Geological Survey, late in the season of 1900; and com- 

 pleted during the field-season of 1902. Separate reports on 

 these deposits are in course of preparation, and as soon as com- 

 pleted they will be published as bulletins of the State Survey. 

 It is the object of this paper to present some of the more im- 

 portant facts brought out in the field and laboratory study of 

 the ocher-deposits of Bartow count}^, Georgia. 



Historical Statement. 



The first authentic record of ocher mined in Bartow county, 

 Georgia, was in the year 1877, when Mr. E. H. Woodward be- 

 gan mining it on a property located near the limits of the town 

 of Cartersville. The crude ocher as mined was hauled in 

 wagons to Cartersville and there prepared for market. Mr. 

 Woodward was engaged at the same time also in mining man- 

 ganese-ores on the Dobbins property, six miles northeast of 

 Cartersville. 



Mining of the ocher on a small scale was continued on this 

 and the adjoining property until 1890, when the Georgia Pe- 

 ruvian Ocher Co., supported by Western capitalists, became the 

 owner of the property, and improved methods in the prepara- 

 tion of the ocher for market were introduced. Hauling to Car- 

 tersville was discontinued on account of the roads, and a plant 

 for preparing the ocher was located at Emerson, two miles south 

 of the mines. The first shipment of American ocher to Europe 

 is reported to have been made in December, 1890, from the 

 Cartersville mines, a consignment of 50 tons having been ship- 

 ped to England. ' 



In 1890, two experienced ocher-men from the East, Mr. J. 

 C. Oram of Vermont and Mr. E. P. Earle of New York, became 

 interested in the company, and modern machinery and improved 

 methods were brought into use. Mr. Oram was the first to in- 

 troduce in the district the natural process of air-drying (sun)
