Another disproof may be found in the ‘fern web,’ ‘bracken clock’ of Scotland; the tiny cockchafer, with brown wing-cases and dark-green thorax, which abounds in some years in the hay-meadows, on the fern, or on the heads of umbelliferous flowers. The famous Loch-Awe fly, described as an alder-fly with a rail’s wing, seems to be nothing but this fat little worthy: but the best plan is to make the wings, either buzz or hackle, of the bright neck-feather of the cock pheasant, thus gaining the metallic lustre of the beetle tribe. Tied thus, either in Devonshire or Snowdon, few flies surpass him when he is out. His fatness proves an attraction which the largest fish cannot resist. The Ephemeræ, too, are far more important in rapid and rocky streams than in the deeper, stiller waters of the south. It is worth while for a good fish to rise at them there; the more luxurious chalk trout will seldom waste himself upon them, unless he be lying in shallow water, and has but to move a few inches upward. But these Ephemeræ, like all other naiads, want working out. The species which Mr. Ronalds gives, are most of them, by his own confession, very uncertain. Of the Phryganidæ he seems to know little or nothing, mentioning but two species out of the two hundred which are said to inhabit Britain; and his land flies and beetles are in several cases quite wrongly named. However, the professed entomologists know but little of the mountain flies; and the angler who would help to work them out would confer a benefit on science, as well as on the ‘gentle craft.’ As yet the only approach to such a good work which I know of, is a little book on the trout flies of Ripon, with excellent engravings of the natural fly. The author’s name is not given; but the book may be got at Ripon, and most valuable it must be to any North-country fisherman. But come, we must not waste our time in talk, for here is a cloud over the sun, and plenty more coming up behind, before a ruffling south-west breeze, as Shelley has it— ‘Calling white clouds like flocks to feed in air.’
