walk about, but when she starts to fly, 

 she spreads them out, a pair on each side 



IfyHp-the two wings ^i^Hon either 

 side iP^were to separate/Wtfromeach 

 other and let the air between them, her flight 

 would be spoiled, and she would go tumbling 

 along in an ungainly and mortifying manner. 

 yThat this may not happen, she 



.hooks the 

 upper 

 large wing'^^^^^^and the lower 

 small one together, when she raises them for 

 flight, so that the two are as firm as though 

 they were but one. She is enabled to do 

 this by a row of hooks on the lower wing 

 which fit into a groove on the , 

 upper 



wing, ^ 



you can see in the "picture. The 

 wings fit so closely together when hooked 

 that you would not discover there were two, 

 unless you looked very carefully indeed.
