3.-A REPORT UPON ICHTHYOLOGICAL INVESTIGATIONS IN 

 WESTERN MINNESOTA AND EASTERN NORTH DAKOTA. 



By Albert J. VVoolman, A. M. 



INTRODUCTION. 



The field work described in this report was carried on during the 

 months of July and August, 1892. The writer was assisted during the 

 first part of the season by Ulysses O. Cox, instructor in biology in the 

 State Normal School, Mankato, Minn. The work was conducted under 

 instructions from the United States Commissioner of Fish and Fisheries, 

 Hon. Marshall McDonald, and under the immediate direction of Mr. 

 Eichard liathbun, assistant in charge of inquiry respecting food-fishes. 



The object of the investigation was to examine the physical features 

 of Big Stone and Traverse lakes, and to make a careful study of the 

 fishes found in them for the purpose of comparing and contrasting 

 the forms found in these two great river systems — the Minnesota and 

 Eed Eiver of the iSTorth — this being the place where they most nearly 

 approach; to observe and record any items of interest bearing on the 

 fishes indigenous to these waters, and to note any other facts that 

 would in any way bear on fish-culture, such as geological features, 

 water supply, vegetation, food supply, and contamination of water. 



In the identification of species I have been assisted by Dr. Barton W. 

 Evermann, of the United States Fish Commission, and Dr. Carl H. 

 Eigenmann, of the University of Indiana.
