56 rROCEEDINGS OF THE ACADEMY OF 



Superior, near the north shore, states that, up to March 2, ores 

 to the value of $250,000 had been taken out, and it is confidently 

 believed that this will be increased before the opening of navi- 

 gation to $500,000. A coffer-dam has been built around the 

 islet,, at a cost of $00,000, to increase the area for working. The 

 ore has thus far been sent to the factory of E. Ballach & Son, 

 Newark, N. J., but works are now about to be built at Wyan- 

 dotte, near Detroit, for the treatment of it. Although the islet 

 is in Canada, and the discoverer is a Canadian, it was not found 

 possible to interest Canadians in the venture of opening the 

 vein, and this extremely promising deposit is therefore the pro- 

 perty of citizens of the United States. The ore is worth about 

 $1500 per ton.
