western or main deposit, which extends from near the present mill 

 where the incline shaft is situated southwest to the limits of the 

 property, a distance of fully one-half of a mile. This has been 

 worked almost entirely underground, the bed which ranges up to 

 30 to 35 feet thick being stoped in drifts which run off from the 

 incline to the southwest. The dip is low, 20° to 25 ° ordinarily, 

 but may change suddenly to 45 ° or 50 ° ; the bed varies greatly 

 in thickness, as it has been squeezed into a succession of bulges 

 and constrictions so that it is in places really a series of lenses 

 separated by varying intervals in which the quartzite is reduced 

 to a thin seam. Occasionally a subsidiary graphite deposit occurs 

 in the foot or hanging of the main deposit. In the last year con- 

 siderable attention has been given to the Summer bed, which for a 

 long time has lain idle. It was opened in the early nineties, mostly 

 by pits situated along the outcrop and following only short dis- 

 tances down the dip. The length of outcrop is around 700 feet. 

 On the northeast end it begins on the surface as a thin band only 

 a foot or so thick, but widens rapidly to the southwest to 6 to 8 

 feet and has recently been mined down to 150 feet on the dip. 

 After another interval it pinches again to a foot or less, only to 

 open out once more, showing that the deposit here also consists of 

 a succession of lenses. The bed has been explored on the dip onto 

 the adjoining Wheeler property, of which the mining rights are 

 held separately. The relations of the two beds have importance 

 in regard to the future mining operations, since the reserves of ore 

 would be likely to be much greater in case there were two distinct 

 beds. The circumstances in evidence, however, point to a repe- 

 tition by faulting of a single ore zone. 



Graphite Products Corporation. This company with mines and 

 mill near Kings station, 4 miles north of Saratoga Springs, was 

 engaged in active production during the year, after having carried 

 out an extensive program of construction and development on the 

 property. The company succeeded to the ownership of the hold- 

 ings of the Saratoga Graphite Co., which had performed little more 

 than experimental work on the property. The mines were enlarged 

 and equipped for economical operation, and a new mill with 15 

 stamps and approved devices for separating the graphite was 

 erected by the company. The year's record of operations was 

 reported as very satisfactory. The graphite appears in two main 

 series of outcrops, which may be displaced parts of a single zone 

 as is the condition on the Dixon property, and the beds have been 

 intruded by amphibolite and pegmatite so that their structures are
