98 The Ottawa Naturalist. [Nov. 



"Partridges" during April and May. A glance up the road-bed 

 certainly did not contradict this assertion. The flesh of the 

 loon, as a rule, is not palatable, and why this species should also 

 be glaringly shot when opportunity offers is questionable. A 

 great number of Gulls have deserted their breeding grounds on 

 the coast, and are now endeavouring to raise their young in 

 secluded localities inland. Year by year, however, the indis- 

 criminate destruction of birds still goes on, and if drastic steps 

 are not soon taken in the direction of protecting them, certain 

 species will be wiped out altogether. Every lake has its quota 

 of rafts, which are used in the springtime for robbing the Gulls.
