There is an erroneous opinion that has gained considerable currency among anglers to the effect that grayling and trout are antagonistic, and that to this cause is to be attributed the decrease of grayling in the waters of Michigan. My observations have led me to the conclusion that this opinion is not supported by any evidence whatever. When I fished the streams of that state, years ago, both trout and grayling were plentiful in the same waters, and were living in harmony as they had done from time immemorial. Their habits and choice of locality being different, the trout hiding under cover and the grayling lying in exposed pools, their struggle for existence or supremacy does not bring them much in opposition, or cause them to prey on each other or on their eggs or fry in an unusual degree, or to such an extent as to effect the marked decrease of either species. Honors are even. It is the same in Montana. In that state the red-throat trout and grayling seek out such portions of the streams as are best suited to them; but very often they are found together on neutral ground, where they live peaceably and not at variance with each other. As no disturbing element has yet been introduced, their numbers still bear the same relative proportion that has existed since the days of yore. Likewise in England, in such historic waters as the Wye, the Derwent, the Wharfe, or the Dove, hallowed by "meek Walton's heavenly memory," the grayling and trout still coexist in about the same relative proportion that has been maintained since and before the days of Dame Juliana Berners, Izaak Walton, and Charles Cotton in the fifteenth century. On those quiet streams no cause has ever been allowed to militate against the well-being of either species, or to disturb the natural conditions to any considerable extent. In a recent number of the _London Fishing Gazette_ is one of the best articles on the English grayling that I have ever seen. It is written by Mr. E.F. Goodwin, who is undoubtedly fully conversant with his theme and well acquainted with the habits of that fish. Among other things he says:-- "When in season I maintain that the grayling will give excellent sport on suitable tackle, is splendid eating, and is as handsome a fish as any angler need wish to gaze upon. What more can one want? How Charles Cotton could have written in such terms of condemnation of the sporting qualities of this fish as to call him 'one of the deadest-hearted fishes in the world, and the bigger he is the more easily taken,' passes my understanding, although we must remember that this remark was passed to 'Viator' on his catching a grayling in the early part of March, when the fish would be out of condition in all probability. I confess to a feeling of disappointment at the summary way in which Walton dismisses the grayling, showing that he did not think very highly of him either from an edible or sporting point of view.
