judged on the basis of the needless slaughter of large birds for 

 which they have no use. 



Of course, the Eagle is wary. Were it not so he would 

 long since have become extinct as far as Ontario is concerned, 

 but even with all his craft, the bird is far less numerous to-day 

 than twenty years ago and is yearly suffering a steady diminu- 

 tion in numbers. He is usually to be seen along the larger 

 bodies of water, and there is no wild thing in which as much 

 interest is taken by the tourist on the steamers, or persons 

 along the lake shore, than the presence of this great bird. 

 "There is an Eagle" is an exclamation that instantly draws 

 the attention of every person within hearing, during travel by 

 boat in the summer, and everyone enjoys seeing these great 

 birds wing their easy way. How splendid it would be if legis- 

 lation could be enacted giving protection which would eventu- 

 ally restore this species to something hke its former numbers. 

 In years gone by every lake of more than a few acres had its 

 pair of nesting Eagles and along the big lakes every few miles 

 would disclose a nest. Within the writer's recollection, in fact 

 within fifteen years, there was along the north shore of Lake 

 Erie a nest more frequently than every ten miles. 



Most hunters and farmers regard big things solely as some- 

 thing to be shot and consequently the Eagle is growing scarcer 

 and scarcer with each succeeding year. 



It seems necessary for every nature lover to take this mat- 

 ter to heart and to make it his personal business to propagate 

 the idea of protection for large birds.
