beetle. By removing the bark of trees the won- 

 derful but destructive work of these beetles may 

 be observed and studied. The praying-mantis 

 is a unique variety which has interesting habits 

 and destroys great numbers of other insects. 

 Frogs and toads render great service in the gar- 

 den and are wonderfully adapted by nature in 

 the structure of the tongue for the work they do. 

 All lady-bugs except one species are beneficial 

 and should be protected. They destroy the San 

 Jose Scale and other serious scale-pests and 

 aphids. Birds prey upon the eggs, larvae, pupae 

 and adult insects. They are natural enemies of 

 insects, and the valuable work they do in keep- 

 ing them in check is not sufficiently understood 

 or appreciated.
