On our way home we entered the Church of "Domine, quo vadis," and looked at the old fragment of the Appian Way, where our Saviour met St. Peter, and left the impression of his feet in one of the Roman paving-stones. The stone has been removed, and there is now only a fac-simile engraved in a block of marble, occupying the place where Jesus stood. It is a great pity they had not left the original stone; for then all its brother-stones in the pavement would have seemed to confirm the truth of the legend.

While we were at dinner, a gentleman called and was shown into the parlor. We supposed it to be Mr. May; but soon his voice grew familiar, and my wife was sure it was General Pierce, so I left the table, and found it to be really he. I was rejoiced to see him, though a little saddened to see the marks of care and coming age, in many a whitening hair, and many a furrow, and, still more, in something that seemed to have passed away out of him, without leaving any trace. His voice, sometimes, sounded strange and old, though generally it was what it used to be. He was evidently glad to see me, glad to see my wife, glad to see the children, though there was something melancholy in his tone, when he remarked what a stout boy J——- had grown. Poor fellow! he has neither son nor daughter to keep his heart warm. This morning I have been with him to St. Peter's, and elsewhere about the city, and find him less changed than he seemed to be last night; not at all changed in heart and affections. We talked freely about all matters that came up; among the rest, about the project—recognizable by many tokens—for bringing him again forward as a candidate for the Presidency next year. He appears to be firmly resolved not again to present himself to the country, and is content to let his one administration stand, and to be judged by the public and posterity on the merits of that. No doubt he is perfectly sincere; no doubt, too, he would again be a candidate, if a pretty unanimous voice of the party should demand it. I retain all my faith in his administrative faculty, and should be glad, for his sake, to have it fully rccognized; but the probabilities, as far as I can see, do not indicate for him another Presidential term.

March 15th.—This morning I went with my wife and Miss Hoar to Miss Hosmer's studio, to see her statue of Zenobia. We found her in her premises, springing about with a bird-like action. She has a lofty room, with a skylight window; it was pretty well warmed with a stove, and there was a small orange-tree in a pot, with the oranges growing on it, and two or three flower-shrubs in bloom. She herself looked prettily, with her jaunty little velvet cap on the side of her head, whence came clustering out, her short brown curls; her face full of pleasant life and quick expression; and though somewhat worn with thought and struggle, handsome and spirited. She told us that "her wig was growing as gray as a rat."

There were but very few things in the room; two or three plaster busts, a headless cast of a plaster statue, and a cast of the Minerva Medica, which perhaps she had been studying as a help towards the design of her Zenobia; for, at any rate, I seemed to discern a resemblance or analogy between the two. Zenobia stood in the centre of the room, as yet unfinished in the clay, but a very noble and remarkable statue indeed, full of dignity and beauty. It is wonderful that so brisk a woman could have achieved a work so quietly impressive; and there is something in Zenobia's air that conveys the idea of music, uproar, and a great throng all about her; whilst she walks in the midst of it, self-sustained, and kept in a sort of sanctity by her native pride. The idea of motion is attained with great success; you not only perceive that she is walking, but know at just what tranquil pace she steps, amid the music of the triumph. The drapery is very fine and full; she is decked with ornaments; but the chains of her captivity hang from wrist to wrist; and her deportment—indicating a soul so much above her misfortune, yet not insensible to the weight of it—makes these chains a richer decoration than all her other jewels. I know not whether there be some magic in the present imperfect finish of the statue, or in the material of clay, as being a better medium of expression than even marble; but certainly I have seldom been more impressed by a piece of modern sculpture. Miss Hosmer showed us photographs of her Puck—which I have seen in the marble—and likewise of the Will-o'-the-Wisp, both very pretty and fanciful. It indicates much variety of power, that Zenobia should be the sister of these, which would seem the more natural offspring of her quick and vivid character. But Zenobia is a high, heroic ode.

. . . . On my way up the Via Babuino, I met General Pierce. We have taken two or three walks together, and stray among the Roman ruins, and old scenes of history, talking of matters in which he is personally concerned, yet which are as historic as anything around us. He is singularly little changed; the more I see him, the more I get him back, just such as he was in our youth. This morning, his face, air, and smile were so wonderfully like himself of old, that at least thirty years are annihilated.

Zenobia's manacles serve as bracelets; a very ingenious and suggestive idea.

March 18th.—I went to the sculpture-gallery of the Capitol yesterday, and saw, among other things, the Venus in her secret cabinet. This was my second view of her: the first time, I greatly admired her; now, she made no very favorable impression. There are twenty Venuses whom I like as well, or better. On the whole, she is a heavy, clumsy, unintellectual, and commonplace figure; at all events, not in good looks to-day. Marble beauties seem to suffer the same occasional eclipses as those of flesh and blood. We looked at the Faun, the Dying Gladiator, and other famous sculptures; but nothing had a glory round it, perhaps because the sirocco was blowing. These halls of the Capitol have always had a dreary and depressing effect upon me, very different from those of the Vatican. I know not why, except that the rooms of the Capitol have a dingy, shabby, and neglected look, and that the statues are dusty, and all the arrangements less magnificent than at the Vatican. The corroded and discolored surfaces of the statues take away from the impression of immortal youth, and turn Apollo [The Lycian Apollo] himself into an old stone; unless at rare intervals, when he appears transfigured by a light gleaming from within.

March 23d.—I am wearing away listlessly these last precious days of my abode in Rome. U——'s illness is disheartening, and by confining ———, it takes away the energy and enterprise that were the spring of all our movements. I am weary of Rome, without having seen and known it as I ought, and I shall be glad to get away from it, though no doubt there will be many yearnings to return hereafter, and many regrets that I did not make better use of the opportunities within my grasp. Still, I have been in Rome long enough to be imbued with its atmosphere, and this is the essential condition of knowing a place; for such knowledge does not consist in having seen every particular object it contains. In the state of mind in which I now stand towards Rome, there is very little advantage to be gained by staying here longer.

And yet I had a pleasant stroll enough yesterday afternoon, all by myself, from the Corso down past the Church of St. Andrea della Valle,— the site where Caesar was murdered,—and thence to the Farnese Palace, the noble court of which I entered; thence to the Piazza Cenci, where I looked at one or two ugly old palaces, and fixed on one of them as the residence of Beatrice's father; then past the Temple of Vesta, and skirting along the Tiler, and beneath the Aventine, till I somewhat unexpectedly came in sight of the gray pyramid of Caius Cestius. I went out of the city gate, and leaned on the parapet that encloses the pyramid, advancing its high, unbroken slope and peak, where the great blocks of marble still fit almost as closely to one another as when they were first laid; though, indeed, there are crevices just large enough for plants to root themselves, and flaunt and trail over the face of this great tomb; only a little verdure, however, over a vast space of marble, still white in spots, but pervadingly turned gray by two thousand years' action of the atmosphere. Thence I came home by the Caelian, and sat down on an ancient flight of steps under one of the arches of the Coliseum, into which the sunshine fell sidelong. It was a delightful afternoon, not precisely like any weather that I have known elsewhere; certainly never in America, where it is always too cold or too hot. It, resembles summer more than anything which we New-Englanders recognize in our idea of spring, but there was an indescribable something, sweet, fresh, gentle, that does not belong to summer, and that thrilled and tickled my heart with a feeling partly sensuous, partly spiritual.

I go to the Bank and read Galignani and the American newspapers; thence I stroll to the Pincian or to the Medici Gardens; I see a good deal of General Pierce, and we talk over his Presidential life, which, I now really think, he has no latent desire nor purpose to renew. Yet he seems to have enjoyed it while it lasted, and certainly he was in his element as an administrative man; not far-seeing, not possessed of vast stores of political wisdom in advance of his occasions, but endowed with a miraculous intuition of what ought to be done just at the time for action. His judgment of things about him is wonderful, and his Cabinet recognized it as such; for though they were men of great ability, he was evidently the master-mind among them. None of them were particularly his personal friends when he selected them; they all loved him when they parted; and he showed me a letter, signed by all, in which they expressed their feelings of respect and attachment at the close of his administration. There was a noble frankness on his part, that kept the atmosphere always clear among them, and in reference to this characteristic Governor Marcy told him that the years during which he had been connected with his Cabinet had been the happiest of his life. Speaking of Caleb Cushing, he told me that the unreliability, the fickleness, which is usually attributed to him, is an actual characteristic, but that it is intellectual, not moral. He has such comprehensiveness, such mental variety and activity, that, if left to himself, he cannot keep fast hold of one view of things, and so cannot, without external help, be a consistent man. He needs the influence of a more single and stable judgment to keep him from divergency, and, on this condition, he is a most inestimable coadjutor. As regards learning and ability, he has no superior.
