WOLF DAYS IN PENNSYLVANIA.

cats, minks and weasels should be allowed ingress to 

 preserves inhabited by game birds, as these animals 

 pre)^ on rats, mice and other pests which are apt to 

 become overly numerous and destroy the eggs and 

 young^of grouse, pheasants and quails. For the same 

 reason hawks and owls should be rigorously pro- 

 tected. If the wolf per se cannot be re-introduced in 

 Pennsylvania, he can be bred hack. The German 

 police dogs, so plentiful in Philadelphia and Pitts- 

 burg, are almost zcohrs; a few generations of wild 

 life and freedom in the mountains would make them 

 zi'olz'cs in every sense of the word.
