 oo-a), or New Guinea. It is found also on 

 Celebes (sel'e-bees), the Philippine {fil'ip- 

 pin), and other islands southeast of Asia. It 

 is about as large as a pigeon, and feeds on seeds, 

 grasshoppers, etc. 



38. Other birds which are remarkable for the length 

 and beauty of their tails are the LYRE-BIRD of Australia 

 and the TROGAN of the Torrid Zone. 



39. The rapidity 

 with which birds can 

 move through the 

 air is astonishing. 

 Few persons have 

 any idea of the force 

 expended in the ac- 

 tion of flight. 



40. Some birds fly 



so rapidly that the strokes of 

 the wing cannot be counted. | 

 The wings of the humming- 

 bird when in motion cannot 

 even be seen. 



41. Let any one try to 

 count the strokes of the wing 

 of a pigeon or of the diving 



sea-fowl, and he will find that it is utterly im 

 possible.
