June 25.RETURNED to New York last night. Out to-day on the waters for a sail in the wide bay, southeast of Staten islanda rough, tossing ride, and a free sightthe long stretch of Sandy Hook, the highlands of Navesink, and the many vessels outward and inward bound. We came up through the midst of all, in the full sun. I especially enjoyd the last hour or two. A moderate sea-breeze had set in; yet over the city, and the waters adjacent, was a thin haze, concealing nothing, only adding to the beauty. From my point of view, as I write amid the soft breeze, with a sea-temperature, surely nothing on earth of its kind can go beyond this show. To the left the North river with its far vistanearer, three or four war-ships, anchord peacefullythe Jersey side, the banks of Weehawken, the Palisades, and the gradually receding blue, lost in the distanceto the right the East riverthe mast-hemmd shoresthe grand obelisk-like towers of the bridge, one on either side, in haze, yet plainly defind, giant brothers twain, throwing free graceful interlinking loops high across the tumbled tumultuous current below(the tide is just changing to its ebb)the broad water-spread everywhere crowdedno, not crowded, but thick as stars in the skywith all sorts and sizes of sail and steam vessels, plying ferry-boats, arriving and departing coasters, great ocean Dons, iron-black, modern, magnificent in size and power, filld with their incalculable value of human life and precious merchandisewith here and there, above all, those daring, careening things of grace and wonder, those white and shaded swift-darting fish-birds, (I wonder if shore or sea elsewhere can outvie them,) ever with their slanting spars, and fierce, pure, hawk-like beauty and motionfirst-class New York sloop or schooner yachts, sailing, this fine day, the free sea in a good wind. And rising out of the midst, tall-topt, ship-hemmd, modern, American, yet strangely oriental, V-shaped Manhattan, with its compact mass, its spires, its cloud-touching edifices groupd at the centrethe green of the trees, and all the white, brown and gray of the architecture well blended, as I see it, under a miracle of limpid sky, delicious light of heaven above, and June haze on the surface below.
