be 



Alarming account of the commercial 

 extinction of valuable species in past 

 years and of the current rapid depletion 

 of still others, followed by a review of 

 the failure of all attempts to obtain 

 adequate regulations through interstate 

 cooperation and an urgent appeal for 

 support of international control of the 

 Great Lakes fisheries.

A call for public support of attempts 

 to obtain immediately discretionary 

 power for conservationdepartments and 

 ultimately international control of the 

 Great Lakes fisheries. Such moves were 

 held to offer the only nneans to obtain 

 the drastic measures needed to save the 

 fisheries.

 aspects of the scale method, a review
