326 FARM FRIENDS AND FARM FOES 



dling this deadly poison ; special pains should always be 

 taken that none of the poisoned materials be left within 

 the reach of children. 



These pests may be caught in traps placed in the burrows. 

 Various forms of traps for this purpose are now upon the 

 market. Gophers may also be killed by the use of carbon 

 bisulphide, a volatile liquid that rapidly vaporizes when 

 placed in the burrow. The vapor is a deadly poison and 

 soon kills any animal that breathes it. It is also inflam- 

 mable, and no fire must be brought near it. 



MOLES AND SHREWS 



There is a small order of mammals called the Insectivora 

 or Insect-eaters. It includes the Moles and Shrews. These 

 animals live mostly in underground burrows and are 

 seldom seen except when turned over by accident. The 

 burrows of Moles are familiar to many people, though 

 doubtless the burrows of Pine Mice are often mistaken for 

 them. Moles feed largely upon earthworms and under- 

 ground insects, but are also often troublesome when they 

 make their runways through lawns and gardens. 



In the great order Carnivora or Flesh-eaters are found 

 many of the large wild mammals, such as bears, wolves, 

 coyotes, foxes, and badgers, as well as a number of smaller 

 ones, such as weasels and ferrets. Many of these are 

 efficient checks upon destructive rodents, but there is 

 comparatively little help to be expected from them in 

 thickly settled regions.
