Wisconsin Historical Society, and has since devoted much 

 energy to the collecting of a second cabinet of copper. He 

 has now about two hundred specimens, many of which are 

 unsurpassed. There are eight axes ranging from two to five 

 pounds in weight. The largest implement weighs ten 

 pounds two ounces. Among this magnificent collection he 

 has ninety spear heads alone. 



IsTear Racine there has been at least one hundred mounds 

 either opened or entirely removed concerning fifty of which 

 I have personal knowledge, and not one single specimen of 

 copper has been discovered in these mounds and as this 

 group i;^ of the oldest type, and as they are situated in the re- 

 gion of abundance of copper, the fact leads to the inference 

 that they were built before copper became of common use 

 among the Indians. This is the more likely as the later 

 mounds have not infrequently articles manufactured from 

 nativecopper. The conclusion follows that the Indians liv- 

 ing at no great distance from the copper regions of Lake 

 Superior did mine copper and make various ornaments and 

 implements, not only for their own use, but extensively for the 

 purpose of barter with distant tribes and nations of Indians. 



PRELIMINARY LIST OF WISCONSIN PARASITIC 



FUNGI. 



By William Trelease, S. D., Professor of Botany, University of Wisconsin. 



The following provisional list of the parasitic fungi of the 

 state includes only species which have been examined by 

 myself. With one or two exceptions, specimens of all have 

 been preserved in my herbarium.' Most of the species were 

 collected about Madison, by myself; although I have received 

 much valuable assistance from Mr. L. H. Pammel, a special 

 student in my laboratory, and a most excellent collector, 



^ Dr. Bundy informs me that none of the fungi enumerated in his list 

 in the first volume of the Report on the Geological Survey were saved, so 

 that I have been unable to refer to them.
