o76 APPENDIX. 



These were more abundant in approaching its southwestern ex- 

 tremity, where they unite in representing it to exist in a solid 

 vein. Specimens of limpid quartz, chalcedony, and striped agate, 

 were also brought to me from this island. [J. S, J. J.] 



2. On the extremity of the great peninsula, called by the na- 

 tives Meenaiewong, or Keweena Point, which forms so prominent 

 a feature in the physiognomy of Lake Superior. It occurs in the 

 detached form. [J. 11. J. J.] 



3. At Point aux Beignes, which is the east cape of the entrance 

 into L'Ance Quewiwenon. A mass from this place was raised 

 from the sandstone rock, which predominates there. [J. Y. B.] 



4. At Caug Wudjieu, or the Porcupine Mountains, Lake Su- 

 perior ; in masses, enveloped with a green crust, along the banks 

 of the Carp, or Neemaibee River, which originates in these 

 mountains. [W. M. G. Y. J. J.] 



5. On the banks of Lac Courterroile. This lake lies near the 

 source of the River Broule, or Cawesacotai, which enters Lake 

 Superior near La Pointe. It occurs in the alluvial soil, which is 

 a kind of loamy earth, with pebbles intermixed, but of a rich 

 quality, and timbered with beech and maple. It is found mostly 

 in small, flat masses, more or less oxidated. [B. Gr. J. G. Y.] 



6. In a vein on the shore of Lake Superior, between La Riviere 

 de Mort and St. John's, a little to the west of Presque Isle. [J, J.] 



7. On the northeast branch of the Ontonagon River. [J. H.] 



8. In the precipitous bluffs called Le Portail, and the Pictured 

 Rocks. A green matter oozes from the seams in these rocks, 

 and forms a kind of stalactites, which is apparently a carbonate 

 of copper. [G. Y.] 



These localities embrace a range of more than two hundred 

 miles along the south shore of Lake Superior, which proves how 

 intimately this metal and its ores are identified with the rocks 

 and the soil of that region. 



(D.) 



In all our calculations respecting the position and advantages 

 of these mines, too much stress cannot be laid upon the facilities 

 of the lake navigation. It is believed that a ton of merchandise, 

 or a barrel bulk, can be transported through the lakes at the 

 same rates that are paid in the coasting trade of the United States.
