 however, so often employed by Messrs. 

 Hume and Marshall and other writers 

 on birds that few sportsmen can plead 

 ignorance of their meaning ; but to avoid 

 any possible misunderstanding on this 

 point it will, perhaps, be desirable to

 are the first ten or eleven quills of the 

 wing, counting from the tip inwards. 

 Many birds have ten primaries, but the

 quills of the wing. About half of these 

 are usually short and of much the same 

 length, and are termed the outer second-
