 killed, and that not one-third of those which came to the surface in fresh water 

 could be sold in the market. 



Acknowledgments. 



The department desires to acknowledge with grateful thanks the receipt 

 from Hon. G. M. Bowers, United States Commissioner of Fisheries at Washing- 

 ton, of four volumes of Jordon & Everman's Bulletin of the United States Nat- 

 ional Museum, and also of a number of volumes of the United States Commis- 

 sioners' Report ; 



The generous consideration and courtesy accorded by various railway and 

 steamboat companies in the matter of transportation ; 



The courtesy of the Biological Department, Toronto, in, from time to time, 

 identifying different species of fish ; and 



The kindness of Mr. S. J. Martin of Kemptville, in sending to the de- 

 partment a very fine maskinonge, which has been mounted and added to the 

 collection which is being made of our game and important food fishes. 



Conclusion. 



In conclusion, it may be unnecessary to say that the work has been con- 

 ducted as economically as possible, having regard to the important and extens- 

 ive duties to be performed, and the report is submitted in the hope that it will 

 meet with your hearty approval. 



The reports of the district and local overseers, which follow, will be found 

 to contain much interesting and valuable information as to fisheries and fishery 

 matters in their respective divisions.
