ACKNOWLEDGMENTS 



It is but fitting that acknowledgment be made of the splendid co-operation and 

 assistance received from the many Fish and Game Protective Associations throughout 

 the Province as well as from the Northern Ontario Tourist Trade Association, and the 

 members of both groups. The result of this organized effort among those directly in- 

 terested in our fish and game resources is refiected in the general attitude of sports- 

 men towards the protection of this division of our Provincial natural resources. 

 Never before has the public generally been more conservation minded, and the part 

 played by these Associations in bringing about this happy state of affairs is greatly 

 appreciated. 



Members of the inside staff as well as the field service of the Department have 

 as a general rule performed their duties conscientiously, and in their dealings with the 

 public have been courteous and helpful, having in mind the various interests and 

 activities of the Department. 



All of which is respectfully submitted. 

 I am, Sir, 



Your obedient servant, 



Toronto, D. J. TAYLOR, 



March 31st, 1941. Deputy Minister of Game and Fisheries
