 on the treatment it receives here, and not upon 

 the number of Redstarts available in the world 

 generally. I am inclined indeed to think, though 

 it is difficult to prove it, that the wholesale 

 slaughter of young birds in our neighbourhood is 

 less horrible than it used to be before the passing 

 of the Act ; but when we remember that other 

 creatures, certain butterflies, for example, whose 

 relations to man never greatly differ from year to

 numbers depends, in the case of migrating birds, 

 on certain causes which are beyond the reach of 

 mankind to regulate. What these may be it is 

 possible only to guess. A famine in the winter 

 quarters would rapidly decimate the numbers of
