If these flies do not answer, it is very rare that you will succeed
with any other. They are suitable for all the rivers and brooks of
Yorkshire, Durham, Westmoreland and Cumberland; about thirty years
experience has convinced me of their entire excellence, and probably
the ingenuity of man cannot devise any to supersede them.
Palmers for March, April, and first week in May,--The March Brown or
Dun Drake,--The Blue Dun,--Early Bright Brown.
_May._--The Dun Cut,--The Cow Dung Fly, and also the March Brown and
Blue Dun are on the waters in late seasons to the middle of the month.
_June._--Little Black Gnat,--The Brown Palmer,--Little Red Spinner--and
Alder Fly.
_July._--The Wasp Fly,--Black Palmer,--July Dun.
_August._--The Late Ant Fly,--The Pale Blue.
_September._--The September Dun,--The Camel Brown and Willow Fly.

NOTE.--If there are no Flies on the water when you begin to angle, try
a Palmer till you find what Flies the fish are taking. One Palmer and
two small hackle Flies on your stretcher give a tolerable good chance.
