The dry fly fisher always fishes up stream. He wades carefully and slowly. When he extends his line for the first cast neither the line nor fly is permitted to touch the water until the fly is traveling through the air three or four feet beyond the point where he expects to get his fish. Then it is permitted to alight gently on the water and to float over the likely spot, care being taken to make it float as life-like as possible and to avoid drag of line or leader pulling it under or upsetting it. If no rise is forthcoming the fly is floated a few feet farther down when it is picked off the water and more false casts are made to extend the line for another attempt and to dry the fly. During this whipping the line back and forth the angler cautiously advances a few feet to cast over fresh water,
