PLEA FOR THE BIRDS. 109 



in general more cultivation than men, are no less de- 

 lighted with them. It is a common weakness of men 

 who are ambitious to seem above every thing that 

 pleases women and children, to affect to despise the 

 singing of a bird or the beauty of a flower. But even, 

 those who affect this indifference are not wholly deaf or' 

 blind. They are merely ignorant of the influence upon;

 pleasures. 



It is not entirely on account of their song, their-

 disturbance in the motions of the spheres, and throw 

 the celestial worlds out of their balance, so would the 

 destruction of any species of birds create confusion

 the multiplication of insects which otherwise would 

 spread devastation over the whole earth. They are 

 always busy in their great work, emigrating from place

 atmospheric insects. Others like the creepers and wood- 

 peckers penetrate into the wood and bark of trees, and. 

 dislodge the larvae before they emerge into the open air.. 

 Besides these birds that do their work by day,- there are-
