THE LAKE LABORATORY. 
Herbert Osborn. 
Most readers of the Naturalist are probably aware that the 
University maintains at Sandusky a lake laboratory, devoted to the 
investigation and study of the life of the lake region. As this 
number of the Naturalist is devoted mostly to reports upon work 
which has been done there, it may be of interest to give some facts 
regarding opportunities offered and the character of the work pro- 
vided for. 
The laboratory was first opened by Professor Kellicott in 1895, 
with a view specially to give opportunity for investigation, and he 
and several of his students engaged in work there through the sum- 
mers of ’95-6-7. Some of the results of these studies were published, 
especially Professor Kellicott’s report upon the Rotifers of Sandusky 
Bay and the list of Odonata for the State, which includes numerous 
records for that locality. During the summer of 1899 the writer and 
several associates occupied the laboratory, and studies upon the 
fishes of the locality, records of Hemiptera and some other groups 
have been incorporated in different papers. In 1900 the scope of 
the laboratory was enlarged so as to provide courses of instruction 
in Botany and Zoology, and a number of students and investigators 
improved the opportunity to work during the summer vacation. 
Reports on the Odonata, sponges, Bryozoa, and the notes on birds 
appearing in the present issue indicate the range of the studies 
engaged in in that season. However, many lines of study which 
were begun by different students and which will require several 
seasons for observations, are not as yet ready for publication. 
It may be noted, however, that the flora of the locality has been 
very thoroughly collected by Professor Moseley, of the Sandusky 
High School, and his publication on the “ Sandusky Flora ” 
furnishes an admirable guide to the location of the various species 
of plants, and an excellent basis for additional investigation. The 
laboratory will at present accommodate twenty-five or thirty students,
