1874.] 201 [Richards. 



It was now necessary to prove a vein in position in the rock and 

 to remove all question of " salting." The earth which had been 

 thrown back into the pit was removed, and then after digging a 

 short time in the harder undisturbed debris of the drift deposit 

 two pieces of galena were found, placed end to end, both of them 

 dipping about 45° N. W., with a strike of about N. 80° E. They 

 weighed respectively about 50 lbs. and 200 lbs. They were com- 

 posed of the minerals previously described; on the north side of 

 each specimen was a thickness of about seven inches of galena 

 and on the south side about three inches in thickness of mixed gray 

 copper, galena, and pyrite. We learned from the farmer who owned 

 the land that he had found all the ore which we had seen in the barn 

 in much the same condition of direction and arrangement. 



Three specimens were assayed, with the following results : — No. 1 

 was a coarse grained galena, very rich in lead and yielded $63.13 of 

 silver per ton of 2240 lbs. No. 2 was a specimen of fine grained ga- 

 lena which was broken from the above-mentioned 200 lbs. mass, and 

 seemed to represent the standard ore of the mine. This gave 50 per 

 cent, of lead and $84.26 in silver per ton. No. 3 was a pure piece of 

 gray copper (taken from the barn) containing a little quartz and ga- 

 lena, and yielded $1,422 of. silver per ton, also $145.12 of gold per 

 ton, and 27 per cent, of copper. The gold was very roughly deter- 

 mined. 



Subsequently the pit was sunk to the depth of about sixteen feet, but 

 the ore and all of its accompanying signs had long since disappeared. 

 But upon consideration it seemed, since the drift of' the glacial epoch 

 moved from the N. W., and the indications pointed to a northeasterly 

 strike for the vein, that if a trench were cut down to the solid rock, 

 in a northwesterly direction, that it must cut across the vein and ex- 

 pose it. Prof. J. M. Ordway of the Massachusetts Institute of 

 Technology entirely corroborated this view of the matter. Accord- 

 ingly a trench was recommended to be made ten to thirty feet, or 

 even fifty feet, long in a northwesterly direction. Recent develop- 

 ments have proved that if the trench had been made as recom- 

 mended, it would have struck the vein at about thirty feet from the 

 first pit, thus proving that the specimens at first found were 

 brought there by the action of the drift. 



'1 he above directions were not followed, but instead, pits were dug 

 in various places, and the amount of float ore taken up in these ex- 

 plorations would seem to be sufficient, in lack of any other evidence,
