With such a variety of offices and engrossing employments still demanding his attention, we should anticipate that the duties would become burdensome, and the skillful hand lose something of its cunning; but the Doctor is still vigorous and works easily. This continued capacity for labor is doubtless owing to the natural endowments of a man who has nurtured his forces by avoiding excesses on the one hand, and on the other by carefully husbanding his strength. He has not only arranged his business on system, but he has resolutely reserved to himself, annually, seasons of almost absolute rest. Retaining his early fondness for fishing, for a few weeks in every year he has resorted to the mountain streams and inland lakes of northern New England for his favorite recreation. In these excursions he has sought the head waters of most of our rivers, and become acquainted with the grand and beautiful scenery of the mountain region. He has learned the haunts and habits of all the fish to be found in our streams, and of the birds that frequent our forests. By this method has he renewed his youth, while, with others of congenial tastes, he has made his knowledge tributary to the public good, by joint efforts to restore the migratory fishes to the waters of the state, from which, by artificial obstructions, they have been shut out. The board of fish and game commissioners for New Hampshire, of which Dr. Spalding is chairman, is an outgrowth of this joint endeavor that promises to enlarge the piscatory resources of the state.
