The drifts are being driven westward and some overhead stoping is 

 being done as well as working down the dip. 



Milling practice. The Graphite Products Corporation, which 

 took an active interest in the property in 191 5, has constructed a new 

 concentration mill, the old one of the Saratoga Company being 

 fitted out as a finishing mill, a little distance away. The usual 

 Adirondack practice is in force : crushing, stamping, buddling, 

 screening and drying. The finishing mill uses Hooper pneumatic 

 jigs which prepare the flake for the market. 



The mill water is secured from the small stream that flows past 

 the mill. The brook valley has been dammed and receives the 

 tailings. The water is filtered through sand banks and used over 

 again. In the late fall the floodgates in the dam are opened and the 

 spring freshets carry the accumulated tailings down stream, empty- 

 ing the reservoir. 



Summary. Cushing says that " much the same assemblage of 

 rocks ." [is shown on both the Flake and Graphite Products proper- 

 ties] " and the general similarity of the rock association strongly 

 suggests that we are dealing with the same rock horizon." 1 With 

 this opinion the writer is in full accord. Isoclinal folding, ac- 

 companied by some overthrust faulting, characterizes the Flake 

 property, while this locality exhibits repeated faulting. This is very 

 fortunate for the Graphite Products Corporation in that it has 

 exposed two beds, and possibly a third. 



Amount of ore. It would seem as if there was a large store of 

 graphite rock on this property, but the complicated structure of the 

 quarry, especially, demands careful work as the operations are 

 continued. 



The " Hulett's Landing " Prospect 



" A very low-grade deposit of graphitic quartzite was discovered 

 by Prof. J. F. Kemp on the east shore of Lake George about 3 miles 

 back of Hulett's Landing. A peculiar" feature of this deposit is the 

 fact that the hanging wall is a very large eruptive dike. As in the 

 Hague mine the ' vein ' seems to have been a line of weakness. The 

 flake of this deposit is very small and of too low grade to be of any 

 value." 2 



Dr W. McKim Marriott reports 3 that in 1916 he collected spec- 

 imens from an outcrop that occurs near Long pond, which he states
