Perhaps the most annoying feature connected with this particular subject is, that in the Hampshire chalk-streams, on a day when the smuts are hatching in great numbers, the largest and best-conditioned fish are ever on the feed, and take not the slightest notice of the most tempting-looking natural duns floating down over their very nose; at the same time they will travel yards to secure a wretched little midge scarcely visible to the naked eye. There must be some specially piquante or attractive flavour in the tiny insect, or possibly a sense of security from the knowledge acquired by ripe experience of the almost insurmountable diffculty to the fly-dresser in imitating so small fly.
