12th of March to 2nd of April
Hen pheasant’s feather does for a fly,
green tail, the wings flat on the body
Dark fur from a hare’s ear for a body
a green shaded partridge feather
 grizzled yellow cock’s hackle
green wax; harl from a peacock’s tail
bright lower body; about the size of pin
the head should be. can be fished from seven a.m.
till eleven; at which time the brown marsh fly comes on.
As long as the brown continues, no fish will take Granham

(Ezra Pound, from Canto LI.)
