THE BIRD STUDY BOOK 



Within these zones the seasons are fixed for the prin- 

 cipal natural groups, water fowl, Rails, shore birds, 

 and Woodcock. In no case does the zone boundary 

 cross a state line, and except in very rare cases the 

 seasons are uniform throughout the states." 



With few changes the regulations were finally 

 adopted. Wherever the federal law conflicted with 

 a state law, the former was regarded as supreme, and 

 to make things more generally uniform the states 

 have since been changing their laws to conform to 

 the Government regulations. After being tried out 

 for three years these rules recently were modified 

 by making five shooting zones and altering certain 

 other provisions. These last regulations which 

 became effective on August 21, 1916, to-day stand 

 as the law of the land affecting migratory birds. 



To the United States Biological Survey was in- 

 trusted the task of enforcing the law by means 

 of game wardens and other officials. That is, the 

 survey was to collect the evidence in cases of viola- 

 tions, and the prosecutions were to be conducted
