the boats below the rapids. Unfortunately connections were not made 

 and the boats were poled back against the current by the guide to 

 reload the freight. At Rush City bridge the expedition had a first 

 glimpse of river house-boats, called "Wahnegans" by the natives. While 

 camping here Mr. Ward discovered a series of 102 mounds covering 

 about 265 paces, which were apparently thrown up by a pocket gopher; 

 some of these mounds were two feet in height. 



At Nevers Dam the expedition found about 15,000.000 log feet of 

 timber held back by the dam. A portage was made here. The large 

 expanse of drowned forest caused by the dam proved of great interest 

 to the expedition and a number of photogTaphs were taken. Equally 

 interesting was the power house at St. Croix Falls, built at an expense 

 of $3,000,000, which supplies Minneapolis and St. Paul with electricity. 



After hauling the boats around the Falls the most interesting 

 region the Dells of the St. Croix, was reached; this region is preserved 

 to the public as an inter-state park. The chief geologic feature of the 

 Dells are the numerous pot-holes on the Minnesota side, and, from a 

 scenic standpoint, a gigantic Maltese cross in the rock on the Wiscon- 

 sin side. The final stop was made at Farmington, where the expe- 

 dition spent several days. Members of the expedition were : Messrs. 

 Ward and his son, Shrosbree, Katze-Miller, Dr. Graenicher, Rohde, and 

 the guide, Clarke. 



Upon motion the meeting then adjourned.
