THE PEST OF BATS 33 



"For effective work," says one who knows, 

 "they require experienced handling and the ad-

 ferrets must be thoroughly accustomed to each 

 other, and the former must be quiet and steady 

 instead of noisy and excitable. The ferret is 

 used only to bolt the rats, which are killed by 

 the dogs. If unmuzzled ferrets are sent into 

 rat retreats, they are apt to make a kill and 

 then lie up after sucking the blood of their vic-

 burrows or escape by other exits and are lost. 

 There is danger that these lost ferrets may 

 adapt themselves to wild conditions and become 

 a pest by preying upon poultry and birds."

 they may be excellent mousers.

 wonders in freeing one's premises if trained 

 to rat-catching. The ordinary farmer's big
