inf;- from 75° at tlie surface to 60° at the bottom of the pit. 

 The outcrop is about 8 feet wide and 12 feet long, but at one 

 end' at least it extends farther to the north-east under a cap of 

 granite. The depoisit, he continues, appears to be what is often 

 called by miners a ' blow-out,' and is probably the result of deep 

 solfataric action, and it should extend to a great depth. He 

 considered that the results so far should be considered very 

 satisfactory and warrant much greater development. 



T had hoped that additional surface work mifiiit prove that 

 the pegmatitic cassiterite-bearing rock extended to some dis- 

 tance, as is the case in most dikes, but Dr. Yomig reports that 

 at the time of his visit a certain amount of stripping in the 

 immediate neighborhood had failed to disclose further outcrops 

 of the tin-bearing body, which seems to be of the nature of an 

 irregular, acid schlieren, closely connected in origin with the 

 containing muscovite granite. He says the light-colored mus- 

 covite granite with which the cassiterite-bearing pegmatite is 

 associated, was seen at a, number of points in the neighborhood 

 and appears to be cutting aj coarser-grained biotite granite.* 



Much activity followed the discovery of tin-ore at this place, 

 and several pegmatite dikes, etc., near ISTew Ross were located 

 and prospected. The Geological Survey found traces of tin in 

 small specimens from a pegmatite dike, 24 feet wide, a mile 

 north of ISTevertell lake, six miles south of Reeves's place. Bis- 

 muthinite and molybdenite were discovered in a silicious and 

 aplitic dike or vein, one mile south of ISTew Ross corner; and 

 tungston ores and rare earths were found in a dike of pegmatite, 

 20 feet wide, one mile east of New Ross Corner, on land taken 

 up, on a license to prospect, by Dr. Lavers and Frank Boylen 

 of ISTew Ross.
