knowledge his overruling Providence so conspicuously 

 exhibited by his measuring them, as it were, and weigh- 

 ing them, and telling them out, so that, their numbers, 

 forces and powers being annually proportioned to the 

 work he has prescribed to them, they may neither exceed 

 his purpose nor fall short of it. 



From the picture I have drawn, and I assure you it 

 is not overcharged, you will be disposed to admit, how- 

 ever, the empire of insects over the works of creation, 

 and to own that our prosperity, comfort and happiness 

 are intimately connected with them ; and consequently 

 that the knowledge and study of them may be extremely 

 useful and necessary to promote these desirable ends, 

 since the knowledge of the cause of any evil is always 

 a principal, if not an indispensable, step towards a re- 

 medy. 



I shall now bid adieu to this unpromising subject, 

 which has so long occupied my pen, and 1 fear wearied 

 your attention, and in my next bring before you a more 

 agreeable scene, in which you will behold the benefits we 

 receive by the ministry of insects. 



I am, &c.
