iology and enough in morphology and embryology to keep it 

 from becoming perniciously exclusive. Aside from the nec- 

 essity of such a laboratory for the survey work it must be said 

 that no state offers more to such a station than our own. We 

 have all the natural conditions in the way of lakes and streams 

 and geographical position. In a country of such great dis- 

 tances it is impractical for many to go to the marine stations. 

 Others who feel that in the future they will have to deal with 

 land and fresh-water forms think it a waste of time and money 

 to study marine life. A sojourn of several months at a well 

 equipped inland station would convince such of their mistake 

 and prepare them for better work. To our army of teachers 

 such a station at one of our principal lakes could offer an 

 opportunity during the summer months of becoming ac- 

 quainted with the modern methods of teaching the biological 

 sciences by being taught themselves how to make the most 

 out of the material and apparatus at their command. From 

 lectures and demonstrations and through association with 

 advanced students and investigators they would gather the 

 general principles and laws of biology as known at the time 

 and would unconsciously catch the spirit that would place 

 them in the proper attitude toward the biological sciences. 

 The time for establishing a fresh-water biological laboratory 

 in Minnesota is ripe, and no citizen can more effectually per 

 petiiate his name than by endowing and equipping such a 

 laboratory as indicated, and his investment can not be made 

 more safely and profitably than under the care of the Univer- 

 sity of Minnesota.
