 other insect destroyers that are now necessary for 

 almost every sucessful farmer and fruit grower to 

 possess. 



DANGER OF IMPORTING FOREIGN SPECIES. 



The importation of foreign species of insects as well 

 as other forms of animal life often results disastrously. 

 Nature aims to restrain the over development of one 

 species by means of another; 



"Small fleas have smaller fleas to bite 'em, 

 And these have smaller fleas ad infinitum." 



and as Mr. Gerald McCai-thy* states: 



"When a species is transported to some distant locality it is 

 apt to leave behind its corelated restraining species, and hence 

 in its new home it is enabled to multiply more rapidly and do 

 more damage than in its native home." 



SOME TROUBLESOME PESTS. 



The (jipsy Moth, introduced by accident into the 

 Bay State, has ravaged a portion of Massachusetts, 

 and over $750,000 have been spent to eradicate this 

 destroyer of foliage, thus far with only partial suc- 

 cess. Investigations proved that many kinds of birds 

 (some of which were called poultry and game destroy- 

 ers) devoured the larvae of the Gipsy Moth. When 

 this became known and it was learned that great num- 

 bers of these feathered benefactors were being de-
