April 30th.–. . . I arose this morning feeling more elastic than I have throughout the winter; for the breathing of the ocean air has wrought a very beneficial effect, . . . What a beautiful, most beautiful afternoon this has been! It was a real happiness to live. If I had been merely a vegetable,–a hawthorn-bush, for instance,–I must have been happy in such an air and sunshine; but, having a mind and a soul, . . . I enjoyed somewhat more than mere vegetable happiness. . . . The footsteps of May can be traced upon the islands in the harbor, and I have been watching the tints of green upon them gradually deepening, till now they are almost as beautiful as they ever can be.
