 with the adaptation of these laws to his own special requirements. 



The evidence of history afiords a second and equally conclusive argument 

 against the theory that the presence of veimin is conducive to the health of 

 the stock. Written records go to show that even in the eighteenth Evidence of 

 century, long before game preserving was introduced, Grouse were ^'^^ory. 

 no less subject to disease than they are at the present day, in spite of the 

 fact that their natural enemies were left undisturbed to keep the "undesirables" 

 in check. As a matter of fact the whole argument is founded on an error. 

 There is no evidence whatever that Nature's so - called scavengers confine 

 themselves to the destruction of the weaklings — their tendency appears to be 

 exactly the reverse. Observation in the field goes to show that the peregrine 

 striking at birds on the wing more often than not picks out the centre bird

the duty of keeping in check the lesser pests, which might otherwise become 



too numerous owing to the destruction of their natural enemies. 



With these facts in view we may proceed to examine the credit and debit 

 account of the various animals that decorate the keepers' " dule " tree to see 

 which should be sacrificed in the interests of sport and which should be 

 spared.

The leading ofi'ender amongst four-footed vermin is undoubtedly the fox — 

 difficult of approach, suspicious of the lure, a ranger of miles of country, one 

 day picking a Grouse from the nest, the next ;_day visiting the 

 farmer's poultry yard, taking his meals sometimes ofl' rabbits, poultry, 

 and Grouse, sometimes off rats, voles, or even frogs, his diet must always 

 be described as promiscuous, his morals noteworthy only by their absence. 

 Even in his methods of destruction the fox is guided by no known law ;
