216 THE MINERAL RESOURCES OF CECIL COUNTY 



There is on the same property a considerable outcropping of buff 

 kaolin, the material showing not only in a test pit, but also in the 

 ditches along the roads. 



The crude material shows moderate refractoriness, becoming vis- 

 cous at cone 30, in the Deville furnace. 



At Broad Creek, underlying the black Patapsco clay, there is a 

 small outcrop of kaolin somewhat similar in appearance to that found 

 in Sutton's cut near Perryville, but containing a larger quantity of 

 iron stain. It is claimed that a first-class washed product was pro- 

 duced here, but that the operations ceased on account of the material 

 giving out. The kaolin crops out in a pit on the south side of the 

 road and also on the north side of Broad Creek. Overlying it is a 

 hard layer of kaolin which has become cemented together and might 

 perhaps serve as a datum plane in further search for kaolin in this 

 region. At the time the deposit was worked, it is said that the water 

 for the washing operation was obtained from Broad Creek, but it 

 seems doubtful whether this stream would be able to supply enough 

 water for the performance of the work all the year round. 



A very white looking kaolin is found on the property of Mr. I. B. 

 Dean at the point f of a mile northeast of the town of Northeast and 

 on the road to Elkton. There seems to be very little stripping 

 necessary but in places the clay is somewhat buff in color. 



A coarse-grained kaolin is found along the Philadelphia, Wilming- 

 ton and Baltimore Bailroad about one mile southwest of Iron Hill, 

 and has been used for lining cupola furnaces. 



Kaolin was also struck on the property of Mr. A. Thiess, at a point 

 two miles due north of Mechanics Valley. The material appears very 

 white in color, and there is practically no stripping, at least this was 

 the case in the test pits which had been sunk to prospect the material. 

 Much of the kaolin is very white. 



Micaceous clay of a residual nature is found in Atkinson's cut on 

 the Baltimore and Ohio Bailroad, two miles west of Leslie. The 

 exact thickness is not known. It is, however, quite refractory, for at 

 cone 27 it shows signs of only incipient fusion. 



An abundance of kaolin was found in sinking a well on the prop-
