6. Beaver. 



This vein is apparently an exception to the general rule in this 

 region as regards direction. It tui-ns north-east instead of north- 

 west, but I am inclined to think that this is a twist produced by 

 contour of ti-ap-nets, and as they open it with more extended levels, it 

 will I believe assume the direction taken by the others. 



Three shafts have been sunk here, but one has been closed up. 

 They ai'e 350 feet from bank here, the vein being from two to four 

 feet wide though considerably split. This is a regular vein and very 

 promising. As this vein intersects a mountain it has been compara- 

 tively easy to mine : three air levels being present, No. 3 being 

 used as an adit. They have encountered gas here at lowest depths. 

 It burns with a pale-blue tlame and is very light, evidently light car- 

 buretted hydrogen gas. That it may be produced by the alteration of 

 the slates into talcose rock at considerable depths is not improbable. 



7. Ontario Vein. 



Formed by the union of two stringers which unite some ten or 

 twelve feet below surface to form a vein a few inches in width. Has 

 not been at all developed. 



8. Rabbit Mountain Vein. 



Of unusual width and at one time extensively mined, but at pres- 

 ent abandoned. Its strike, dip, and the general character of the 

 mineral the same. 



9. Big Bear. 



A promising vein though it has been but slightly opened up. 



10. Caiiboit. 



This has alsO been considerably mined, but at present not worked. 



I believe this region must ultimately take a foremost place among 

 the silver mining districts of America. My reasons are these : First, 

 the universal excellence of the ore ; while much is extremely rich run-
