This is a famous fly, and is known on most English 

 rivers, and by a great variety of names the iron blue dun, 

 iron blue drake, little iron blue, little water-hen, little 

 dark dun, &c. Jackson calls it the pigeon blue bloa. 

 In his "Book on Angling," Mr. Francis overlooks it 

 in Jackson, and says, " Jackson does not give this fly till 

 June, though all other authors introduce it in April." It is 

 No. 14 on Jackson's plates, Mr. Francis having mistaken 

 No. 39 for it. Jackson gives the dressing for his No. 14, 

 almost identically with No. 20 as above, except that he 

 adds the tail. On the Eden it is dressed from the breast of 

 the cock Water-hen.

 will often kill well on cold days all through the season.

 whilst it is on trout commonly prefer it to anything else.

 at when it reaches the surface of the water, newly hatched
