(A writing to Dewey Gillespie from a very respected friend AJH)

Duke Of Sutherland

The angler with a knowledge of aquatic insects and the important relationship they bear to the fish he wants to catch is better equipped with a single fly, than is the angler who knows nothing of such things though he sports a jacket full of boxes stuffed with crisp, unmouthed flies of every description. 

It is better to fish a fly that will catch a fish than to hunt a fish that will take a fly.
