thicker of the two, is the one chiefly mined. The two beds are 

 exposed on the other side of the fault while the Stmmier pit is located 

 in the upper stratum. Considerable ore has been removed along 

 the strike, but less along the dip as the line of the company's property 

 is close by. The dip of the bed averages about 25°, but it frequently 

 increases locally to 25° or even 45°. During the past year the 

 American Graphite Company has not been operating at full capacity, 

 being engaged in diamond drilling for exploratory purposes. 



The Faxon property. The adjoining property held by William H. 

 Faxon is still undeveloped, although more or less explored. The 

 same geological conditions prevail on the Faxon property as on the 

 former. Two main workable areas are available, one is the continua- 

 tion of the main bed of the Dixon ore, the other is the Summer 

 bed where it occurs on what is known as the Wheeler lot. The ore 

 is frequently cut by minor faults. The supply of ore on this property 

 is undoubtedly very large and the local conditions are favorable 

 for mining. 



The Graphite Products Corporation. This company is operating 

 a deposit 4 miles north of Saratoga where the graphite schist outcrops 

 as two parallel strata due to repetition by step faulting. The rocks 

 strike east and west and dip 32° to the south. The northern outcrop 

 is the only one now being worked, the ore being quarried. There 

 is a mass of metamorphosed gabbro and a diabase dike that interrupt 

 the beds and cut across the graphite member. Concentration is 

 accomplished by buddies, tables and screens. Hooper air jigs are 

 employed in the refining process. The ore reserves of this property 

 seem to be extensive. 



Hooper Brothers. Another recently developed property is situated 

 2 miles west of South Bay of Lake Champlain and appears to be 

 a promising enterprise. The bed of ore outcrops on the face of a 

 steep cliff where both open-cut and underground methods are 

 employed in extracting the schist. The ore is hoisted by cable cars 

 into a mill located on top of the ridge where the usual method of 

 concentration is practised, although considerable changes in equip- 

 ment are being made. 



Flake Graphite Co. A comparatively new-comer in the field is 

 the Flake Graphite Co. The mine is situated 2 miles west of Porter 

 Corners and 8 miles west-northwest of Saratoga. The geological 

 conditions prevailing at this locality are very similar to those 

 obtaining on the property of the Graphite Products Corporation. 

 In fact it occurs in another portion of the same block of Grenville 

 strata. Here isoclinal folding characterizes the locality. Mining
