THE ADIRONDACK GRAPHITE DEPOSITS 2$ 



The nature of the deposit is against profitable mining. The ore is 

 very pockety and too variable to furnish any large supply. Mr 1). 

 G. McGrew, formerly connected with the company, and Mr Samuel 

 Buck gave assistance and furnished information concerning this 

 property. 



The Mason Property 



Location. This property lies in the township of Ticonderoga, 

 three-eighths of a mile east of Echo lake on the shortest road from 

 Ironville to Ticonderoga by way of Echo lake and Street road, the 

 exact location being south of the road on a farm owned by Mr. 

 Mason. Although only prospect work has been done, samples of 

 the unusually large flake, some of which measured i l / 2 inches in 

 diameter, were sent to the American Graphite Company's mill at 

 Ticonderoga but were found to be too large for treatment. The 

 band of ore (the "vein" of the miners) strikes north 13 west 

 (magnetic) and is said to be traceable for 20 to 30 rods, along 

 which line nine openings have been made. 



The size of the flake seems to grow smaller with depth from the 

 surface. Mr Mason claims 12 per cent of graphite in the ore. 

 Mica occurs on the southwest or hanging wall. The dip is very flat. 

 The rocks shown here are limestone and pegmatite. One specimen 

 of the latter carries black tourmaline. Like most of the deposits in 

 limestone, the ore is localized in pockets and is exceedingly patchy, 

 hence it is difficult, if not impossible, to estimate the quantity, but in 

 all probability the supply is small. 



The origin of the ore is clearly due to the action of the pegmatite 

 upon the limestone, presenting the usual characteristics. 



Lead Hill 



Location. The property lies 3 miles northwest of Ticonderoga 

 in the township of the same name and likewise within the Ticon- 

 deroga quadrangle, north of the " new " road to Eagle lake. 



The extent of the property is considerable, comprising an area 

 of several acres. There are numerous pits scattered over the 

 southern and southeastern slopes of the hill, the important ones 

 being shown on the accompanying map (figure 3). 



History. As far as the writer has been able to ascertain, this 

 property was the first to be exploited for graphite in the United 

 States. It was well known that graphite occurred here in 1842, for 

 Emmons savs 1 that it " is well known at Ticonderoga where it forms
