casting the fly as for salmon or trout, and this is by far the most sportsmanlike way, but the most destructive and usually resorted to is trolling." The only personal experience he gives of black-bass fishing, unfortunately, is by trolling with large flies. In his "Game Fish of the North," 1862, he devotes five pages to the black-bass, but apparently does not discriminate between the two species. In "Superior Fishing," 1865, he devotes two pages to the black-bass of Canada and the Great Lakes, in a general way, but gives two instances of fishing as follows, "Pedro soon hooked a splendid black-bass, and landed him after a vigorous struggle of half an hour; he weighed three pounds and three-quarters, and was thoroughly game." And again, "That evening was again devoted to the black-bass, which took both the fly and spoon greedily." During the period covered by the authors named, from 1849 to 1869, the anglers of the South and Middle West were using light cane rods, Kentucky reels, and the smallest sea-grass lines for bait-fishing, and trout fly-rods and trout-tackle for fly-fishing, rods and tackle as light, to say the least, as those in use to-day. In 1866 I removed to Oconomowoc, Wisconsin, where there were thirty lakes within ten miles abounding in black-bass of both species, with pike, rock-bass, crappies, perch, etc. On my home grounds was a large shallow pond fed from Fowler Lake. Becoming much interested in the black-bass, and finding but little information available in the books of that day concerning their habits, I determined to give some study to the subject. Accordingly I cut a ditch from the pond to the lake, with suitable screens, and stocked it with black-bass of both species. During their spawning period in the summer I watched them faithfully and constantly from a blind of bushes on the bank. This I did for several years, turning the adult bass into the lake when the fry were large enough to look out for themselves, and turning the fry out also in the fall. I extended my observations of the bass during their breeding season to the many lakes near by. I found a difference of several weeks in the time of their spawning in these lakes, owing to the difference in temperature, caused by their varying depth. The appearance of the bass also differed slightly in the various lakes, so that it was possible, from a close study of their variations in color, size, and contour, to determine in what particular lake any string of bass was taken.
