154 INJURIOUS INSECTS OF 1904. 



and clover meadows. About two per cent of all crops destroyed. 

 Throw up hills in clover meadows, which are injurious to machin- 

 ery ; often eat off all roots of large apple trees and destroy trees. De- 

 stroy carrots and potatoes. Considerable damage in hay land. Dam- 

 age to apple and evergreen trees. Damage grain and meadows and 

 trees by throwing up mounds of dirt and gnawing roots of trees. 

 Damage grain shocks by carrying dirt into them and eating heads of 

 grain. Considerable damage to shocks of grain. Troublesome in 

 gardens and potato patches. Destroy young trees."

 no damage. Scarce. Not numerous ; eat grain. Damage very

 Very few of them; dig up and eat seeds just planted."

 later. Bearing these facts in mind, it will be seen that some of 

 our correspondents, who write as follows, must be mistaken: "Eat 

 bark of apple, plum, cherry and other trees. Also damage hay 

 stacks by chewing up hay in little pieces." This party is un- 

 doubtedly ascribing the work of mice to moles. Another says "In-

REMEDIES. 



Jack Rabbits: These are kept in check somewhat by gunners 

 and other natural enemies. Poisoning apple or pieces of melon 

 with strychnine, powdering the same and introducing it into slits 

 in the fruit has been tried with some success. One must bear in
