224 Wild Life in a Southern County 



turning yellow, and where the grain is not yet developed. 

 Except perhaps where they are very numerous, they do 

 much more good than harm. 



Books may now and then be seen in the autumn, on 

 the hayricks ; they pull the thatch out, and will do in this 

 way an injury to the roof. Therefore old black bottles are 

 often placed on the thatch in order to scare them. It is 

 said that they pull out the straw for the stray grains left 

 in the ear by the thrashing-machine. This seems doubt-

 the straw attracts them. 



If you are walking past a feeding flock, the nearest

 whether he shall fly or not. He stretches his neck and

 and glides a dozen yards to alight once more. 



Sometimes a flock will rise in the air, and silently 

 wheel round and round after each other, gradually ascend-

 falls at a great pace, and looks as if he must be dashed to 

 pieces against a tree or the earth ; but he rights himself 

 at the last moment, and glides away and up again with
