The indications which tell your dry fly angler when to strike are clear and unmistakable, but those which bid a wet fly man raise his rod-point and draw in the steel are frequently so subtle, so evanescent and impalpable to the senses, that, when the bending rod assures him that he has divined aright, he feels an ecstacy as though he had performed a miracle each time.
G. E. M. Skues
