THE LAKE LABORATORY. 

 Hekbert 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-?. 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 Heiniptera 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 floi'a 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 i^lants, and an excellent basis for additional investigation. The 

 laboratory will at present accommodate twenty-five or thirty students,
