It is a great advertisement of the zeal and multitude

of fishermen--for whom the year has just begun—that the colour sense of fish has. been under vigorous discussion for generations. The bibliography on the subject is immense. mense. and quite beyond parallel. Mr. Bernard—whose Fly Dressing (Herbert Jenkins, Ts. 6d.) is the latest addition to the theme- - brings a peculiar gift of. common sense to the problem. Ile floats the flies on water in a clear glass bowl and looks at theirs from underneath ; and by this simple device puts himself in the fishes' place. He comes to the conclusion that the wings of a fly are much the least important part. Flies that settle on the water usually keep their wings more or less vertical ; and in any case the bits of a fly that touch and penetrate the surface are of a vastly superior distinctness to all the rest.
