 certain beetles which represent the fin flew of insect 

 peerage, then new-comers must command success by 

 other means, and these they employ from the first 

 moment of their children's lives. By giving their 

 young a start in instinct, in position, in surroundings, 

 they do much. But initial advantages such as these 

 are not enough to maintain the struggle, limited as 

 it is to a few months each year. The spurt must 

 be followed up by rapid growth to maturity, and by 

 a succession of broods with powers of securing new 

 stations, and so immolating themselves in the aggrand- 

 isement of the race. 



It is with this hurly-burly in mind that we appreciate 

 the contrast of the fly, which grows up in ten days, 

 with the locust, which leisurely pursues its childhood 

 for a year or more. It is this competition for the 

 success of the family within the limits and by the gifts 

 of summer, that has raised bread-winning to such a 

 high art, so diversely followed, according to the age 

 traditions and genius of the different orders of insects. 



The earliest traditions of insect history, unlike
