For the work in hand many of the lakes 
were available. Our location was therefore 
determined by the finding of an old boat- 
house suitable for a laboratory on the shore 
of Turkey Lake. 
For the first year the trustees of the 
university granted the use of the apparatus 
of the zoological department provided the 
station would in no way be an expense to 
the university. After the first year the 
trustees provided generously for the per- 
manent equipment of the station. To help 
defray expenses a number of courses of in- 
struction were offered for a few students.

Certain restrictions reduced this number 
to 91 during the present season. The large 
increase in the number of students kept us 
more than busy to provide for their increas- 
ing needs, but the collection of the material 
for the study of variation was not neglected. 
At the end of the fourth year the station 
was moved to Winona Lake where the 
facilities for caring for the increasing num- 
ber of students are much better. Two 
buildings were erected and given to the 
station by the Winona Assembly and Sum- 
mer School. They are situated in the angle 
where Cherry Creek enters Winona Lake,

It was expected that there would be about 
ten in the party the first year, but there 
were nineteen. 
The conditions for biological work, 
coupled with camp life on a fine lake, five 
miles from the nearest village and free 
from university lecture-hour appointments, 
proved so attractive that during the second 
summer the number of students rose from 
nineteen to thirty-two, and in the third to 
sixty-three, and in the fourth to 103, repre-

eighteen miles from the original location. 
They are surrounded. by a great variety of 
natural conditions of water, woods, swamps 
and meadows. The buildings are 20 by 45 
feet. One or both will be lengthened to 60 
feet during the winter. 
The special feature in the construction 
is the cement floors of the ground story. 
This arrangement makes the tables on these 
floors nearly independent of people moving 
in any part of the buildings. On one of 
these floors there are private laboratories,
