DIRECT INJURIES CAUSED BY INSECTS. 81

 low in their train. 



The generality of mankind overlook or disregard these 

 powerful, because minute, dispensers of punishment ; 

 seldom considering in how many ways their welfare is

 our bodies, our clothing, our houses, our cattle, and the

 exposed to all the extremities of want and famine ; and

 ject, has well observed*, driven with all the larger ani- 

 mals from the face of the earth. You may smile, perhaps, 

 and think this a high-coloured picture, but you will re- 

 collect — I am not stating the mischiefs that insects com- 

 monly do, but what they would do according to all pro- 

 bability, if certain counter- checks restraining them within 

 due limits had not been put in action ; and which they

 sesses or has possessed animal or vegetable life, is safe 

 from their inroads. Neither the cunning of the fox, nor
