We must observe that wliilst we read in 

 nature's book, every page affords instruc- 

 tion ; the iirst ordination as given by the 

 great Creator, " increase and multiply" 

 aided by nature's first impelling instinct, 

 self preservation, is fully exemplified in 

 every lesson, and as men and rational 

 beings we should always bear in view the 

 determination as expressed, " By the 

 " sweat of thy brow shalt thou, &c. &c." 

 And should know that it is expected of us, 

 to use our utmost endeavours to curtail 

 the superfluities of nature's works, and 

 render those things committed to our 

 care as perfect as our intellect and indus- 

 try will admit. 



I shall endeavour to illustrate the above 

 facts, by giving the history of some of our 

 most noxious insects.
