PREFATORY NOTE 



6-7 EDWARD VII., A. 1907 



(Queen's University). The effects of dynamite, illegally used in fishing operations, 

 and the actual and unquestionable results of sawdust pollution in waters frequented 

 by fish, have been investigated with thoroughness and rigid accuracy, for the first time 

 in Canada, under the auspices of the Marine Biological Station. Intense public in- 

 terest has been aroused by the publication of the preliminary accounts of Professor 

 Knight's prolonged and laborious investigations, and the final reports are included in 

 the present series. 



Dr. Joseph Stafford, who for some years has devotedly performed the duties of 

 curator at the station, and year after year, has spent the whole season from the opening 

 to the close, in f aunistic, fishery and other studies, especially the study of fish-parasites, 

 contributes further interesting papers, and it is important to note how many of the 

 universities of the Dominion have sent workers to the Marine Biological Station. 

 Toronto and McGill Universities have been prominently represented. Queen's Uni- 

 versity, Kingston, has almost every season sent some representative of its academio 

 staff, while Dalhousie (Halifax), Mount Allison (Sackville, N.B.), Acadia (Wolfville, 

 N.S.), and other universities, including some United States' institutions have sent 

 workers. The station has been hampered in various ways, by the limited nature of its 

 reference library, but especially by the lack of a suitable fishing launch fitted, for in- 

 vestigating deep-sea grounds. These wants are happily being gradually supplied, the 

 library already embraces a valuable and representative series of memoirs and reference 

 works, and with due encouragement the Marine Biological Station of Canada will ere 

 long rank as one of the best and most valuable fishery research institutions on this 

 continent.

 Dominion Commissioner of Fisheries.
