40 THE REPORT OF THE No. 31 



M notable contrast to that of some of the States, and the result has been a conservation of the 

 " fish supply which would not have been obtained under other conditions. 



M Again assuring you that it will give me great pleasure to confer with you on this impor- 

 14 tant subject, I am, sir, 



"Very respectfully yours, 



"J. L. RODGERS, 



"President." 



A conference will probably be held as soon after the approaching session of 

 the Ontario Legislature as details can be arranged. 



The Biological Station in the Georgian Bay. 



The biological station, which has been recently established by the Domin- 

 ion Government in the Georgian Bay, is situated on island No. 121 in Go- 

 Home-Bay, about twenty miles from Midland. Scientific work was begun 

 there last summer. An application was received from the station for permission 

 to use certain nets to enable the work for which the station was established to 

 be carried on, which permission was, of course, promptly granted. A complete 

 hydrographic survey of the vicinity is being made under the supervision of 

 Professor C. H. C. Wright, of the School of Science. Last season a surface map 

 of the islands and reefs lying between Station Island and Red Rock was finish- 

 ed, and this survey, it is understood, will be extended next summer. The bio- 

 logical work is under the direction of Dr. B. A. Bensley, of Toronto University, 

 who, it may be said, is now making a classification of the fish of the Georgiau 

 Bay from specimens taken last season, a full list of which will be published as 

 soon as completed. One of the chief features of the biological work will be a 

 study of the food and environment of the fish of the district, with special refer- 

 ence to those of commercial value. Mr. R. T. Anderson, a student of the* Univer- 

 sity of Toronto, has made a large collection of the skins of lake and marsh birds, 

 which is to form the nucleus of a complete collection of the birds of the region. 

 He is also making a collection of the plants and animals of the surrounding 

 country. In addition to the strictly scientific work of the station, work of a 

 more practical and commercial nature is being carried on — a hatching pond for 

 bass was last fall prepared, and twenty-nine bass of different ages were placed 

 therein. If they winter successfully, their spawning operations are to be care- 

 fully studied. The preparation of another hatching pond for bass is contem- 

 plated next season that the effect of food and environment may be determined, 

 as well as the growth from year to year. Meteorological observations were 

 made during the summer, under the supervision of Professor W. J. Loudon, and 

 arrangements are being made for more complete meteorological records during 

 next season. 



There is an infinite variety of fish fauna at the very door of the station. 

 Fish are being caught daily at all stages of their growth. We have no reliable 

 information as to the time it takes them to arrive at maturity — the matter has 

 been one of speculation largely. It is a subject of great interest from an 

 economic standpoint, and it would be most desirable that the purview of the 

 station should be extended to other kinds of fish as well as bass, that some 

 organized means of obtaining this very useful information may be evolved. 



The effect of Dynamite Explosions upon Fish Life. 



Reference was made in the report of last year to permission having been 

 granted to Dr. A. P. Knight, Professor of Animal Biology Queens College, King- 

 ston, to make tests in provincial waters as to the effect of dynamite explosions
