THE GEOKGIAN BAY BIOLOGICAL STATION. 



EePORT of OPERATION'S, 1904. 



The Georgian Bay Biological Station was open for biological study 

 from June 2nd to September 5th. The following gentlemen were in 

 attendance during the H.Lole or a part of this period: — Mr. A. P. 

 Gundry, B.A., Science Master, Brantford Coll. Inst.; Mr. J. M. Cole, 

 M.A., Woodstock Coll. Inst.; Mr. L. C. Coleman, B.A., Assistant in 

 Zoology, University of Toronto ; Mr. A. G. Huntsman and Mr. Davidson 

 Black, advanced students of the University of Toronto. 



The early part of the season was devoted to study of the spawning 

 habits of fishes, and particular efforts were made towards the artificial 

 rearing of the small-mouth bass in the laboratory. These were attended 

 with a fair measure of success, but the number of eggs obtained was 

 not large, and further experiments will be made during the coming 

 summer. 



A preliminary study of the plankton was made by Mr. Huntsman, 

 who also made a series of preparations of the chief types. A collection 

 of young bass in different stages of growth was made for the purpose 

 of a study of the rate of growth, plankton elements of the food, and 

 parasites. Mr. Huntsman also practically completed the collection of 

 flowering plants begun in 1902 by the late Mr. E. T. Anderson, labelled 

 and mounted the majority of them, and submitted a report of the local 

 species. 



Mr. J. ]\I. Cole made a preliminary collection of aquatic molluscs, 

 and a similar collection of aquatic insects was made by Mr. Gundry. 

 Mr. Black continued the collection of birds begun by Mr. Anderson, 

 made many additions to the series of dried skins, and has submitted 

 a report on the species now present in the collection. 



The collection of fishes, amphibians, and reptiles, completed during 

 the summer, has been worked over by myself, and these will form the 

 basis of a special report. 



The appointments of the station have been greatly improved. 

 Appliances have been added in the laboratory, and a pumping apparatus 

 has been installed to ensure a good water supply to the building. A 

 separate building has been erected at the farther end of the station 

 island to serve as a residence for workers. It contains a dining room, 

 kitchen, and nine bedrooms, and is adequately furnished. The erection 

 of this building has removed the heretofore serious obstacle of living 

 accommodation.
