About the same time, from 1868 to 1870, Mr. Cyrus Mann and Mr. H.D. Dousman established their trout hatchery and ponds not far from Oconomowoc, and Colonel George Shears, of Beaver Lake, a few miles away, also began hatching trout on a smaller scale. These establishments presented an opportunity to study the artificial propagation of brook-trout, and I soon became familiar with the _modus operandi_. This was before the institution of the United States Fish Commission, though the state of Wisconsin already had an able and efficient Fish Commission, Mr. H.D. Dousman being one of the commissioners. Colonel Shears also experimented with black-bass culture, and between us we reared many thousands to the age of three months, before turning them out. Near my pond was a shallow, marshy cove to which the pike resorted in early spring to spawn, giving me an opportunity to study their breeding habits, also. There being so many lakes and ponds in the vicinity, and their being so well supplied with fishes of various kinds, my opportunities for the observation of fish life were as great as fortunate. The differences of opinion among anglers, of all men, pertaining to the practice of their art, has become axiomatic. Some will differ even to the estimation of a hair in the legs of an artificial fly, while it is averred others will go so far as to "divide a hair 'twixt south and south-west side," as Butler has it. But, seriously, there are several moot points which I have endeavored to discuss in the following piscatorial polemic. Two friends went fishing. Both were famous black-bass anglers, with the enthusiasm born of a genuine love and an inherent appreciation of the gentle art so common among Kentucky gentlemen. One was a fly-fisher, the other a bait-fisher. Each was a devotee to his especial mode of angling, though generously tolerant of the other's method. They had fished together for years when the dogwood and redbud blossomed in the spring, and when the autumnal tints clothed the hillsides with scarlet and gold. They differed in their methods of fishing from choice, or from some peculiar, personal idiosyncrasy, for each was an adept with both bait and fly. But this difference in their piscatorial practices, like the diversity of nature, produced perfect harmony instead of discord. Each extolled the advantages and sportsmanship of his own method, but always in a brotherly and kindly manner; never dictatorial or opinionated in argument, or vainglorious and boastful as to his skill, for both were possessed of the generous impulses of gentlemen and the kindly influences of the gentle art. Moreover, they were innately conscious of a common aim, and differed only as to the ways and means of best attaining that end, which, while dissimilar, were not inharmonious.
