June 4, '80.—For really seizing a great picture or book, or piece of music, or architecture, or grand scenery—or perhaps for the first time even the common sunshine, or landscape, or may-be even the mystery of identity, most curious mystery of all—there comes some lucky five minutes of a man's life, set amid a fortuitous concurrence of circumstances, and bringing in a brief flash the culmination of years of reading and travel and thought. The present case about two o'clock this afternoon, gave me Niagara, its superb severity of action and color and majestic grouping, in one short, indescribable show. We were very slowly crossing the Suspension bridge-not a full stop anywhere, but next to it—the day clear, sunny, still—and I out on the platform. The falls were in plain view about a mile off, but very distinct, and no roar—hardly a murmur. The river tumbling green and white, far below me; the dark high banks, the plentiful umbrage, many bronze cedars, in shadow; and tempering and arching all the immense materiality, a clear sky overhead, with a few white clouds, limpid, spiritual, silent. Brief, and as quiet as brief, that picture—a remembrance always afterwards. Such are the things, indeed, I lay away with my life's rare and blessed bits of hours, reminiscent, past—the wild sea-storm I once saw one winter day, off Fire island—the elder Booth in Richard, that famous night forty years ago in the old Bowery—or Alboni in the children's scene in Norma—or night-views, I remember, on the field, after battles in Virginia—or the peculiar sentiment of moonlight and stars over the great Plains, western Kansas—or scooting up New York bay, with a stiff breeze and a good yacht, off Navesink. With these, I say, I henceforth place that view, that afternoon, that combination complete, that five minutes' perfect absorption of Niagara—not the great majestic gem alone by itself, but set complete in all its varied, full, indispensable surroundings.
