NOTE -BOOK OE A NATURALIST. 93 



whereiu Avere two young, one of wliicli appeared nearly 

 three times as laro-e as the other. One of these nestlino-s 

 might have had the Ron's share of the food brought by 

 the parents ; but tlie story of the hatching at long in- 

 tervals is so contrary to all known rules of incubation, that 

 it must be received with the greatest doubt. 



"We must leave the grand native solitudes where this 

 eagle constructs his eiry for the cabined, cribbed, con- 

 fined cell, where our poor prisoners did their best to obey 

 nature's law. 



The female began to sit on her eggs on the 8th of

 which I have in a former chapter alluded, is very great. 

 A person near Norfolk, U. S., informed AVilson, that in 

 clearing a piece of woods on his ground they met mth a 

 large dead pine-tree, on which was a nest of one of these 

 birds containing young. Fire was set to the tree, the 

 crackling flames ascended, the tree was in a blaze more 

 than half-way up ; the wretched parent darted round and 

 round through the fire until her plumage was so much 

 injured that it was with difficulty she made her escape, 

 and, even in that condition, she several times attempted 

 to return, all the mother rising in her, and driving her to 

 attempt the relief of her doomed nestlings. 



In a dissection by Dr. Samuel Smith, of Philadephia 

 the eggs were found to be small and numerous; and this,
