providing he believes that the spot he last floated his fly over is barren of possibilities.
The dry fly fisher must at all times keep in mind the fact that he is imitating nature as closely as possible. His flies are almost exact duplicates of the living insect and he must make his fly float as naturally as he knows how. When the fly is on the water the slack line is slowly taken in by the caster's left hand, or rather the fingers of the left hand, but at no time should the line pull on the fly which should be floated solely by the current. While I have taken trout on flies that were handled in an unnatural manner the true-to-nature-idea is a good one for the dry fly fisher.
