area under exploration. The graphitic quartzite that constitutes the 

 principal ore body has a thickness ranging from 5 or 6 to 25 feet, 

 showing local pinches and bulges as is usual in the Adirondack 

 deposits. There is considerable variation in the size and abundance 

 of the flake, but as a whole the character of the quartzite is quite 

 Hke that in the American mine. Near the southwestern end of the 

 property the graphite series outcrops in a little ravine where a short 

 drift has been extended into the north bank; two distinct beds are 

 found here separated by a band of garnetiferous gneiss. In a drill 

 hole (No. 2) 300 feet or so northeast of the drift a similar relation 

 holds, the upper bed measuring about 4 feet and the lower 18 feet 

 thick with 26 feet of gneiss between them. The two beds appear to 

 merge a little further northeast for in No. 3 drill hole just east of 

 the camp a single seam over 20 feet thick was encountered and this 

 apparently continues with local variations as to thickness to the 

 northeastern limits of the property, except in one place where the 

 series is invaded by a gabbro intrusion. The deepest hole, No. 7, 

 was put down in the flat about 600 feet east of No. 3 and twice that 

 distance from the outcrop of the graphite bed on the ridge to the 

 northwest. The data for this boring have been kindly supplied by 

 Mr Faxon and are illustrative of the general conditions under 

 which the graphite occurs.
