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 theircommand. 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- 
petuate 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.
