NATUEE AND THE POETS 91 



set the example to the poets that have succeeded 

 him of closely studying Nature as she appears under 

 our own skies. 



I yield to none in my admiration of the sweetness 

 and simplicity of his poems of nature, and in gen- 

 eral of their correctness of observation. They are 

 tender and heartfelt, and they touch chords that no

 observer; he sometimes tripped upon his facts, and 

 at other times he deliberately moulded them, adding

 all birds are armed with a small temporary horn or 

 protuberance upon the upper mandible, and they

 are fully developed and begin to struggle to free
