There is but one hotel for American travellers in Bologna, of course. Those who have read Rogers's Italy, will remember his mention of "The Pilgrim," the house where the poet met Lord Byron by appointment, and passed the evening with him which he describes so exquisitely. We took leave of our motley friends at the door, and our artists who had greatly admired the lovely Venetian, parted from her with the regret of old acquaintances. She certainly was, as they said, a splendid model for a Magdalen, "majestical and sad," and, always in attitudes for a picture: sleeping or waking, she afforded a succession of studies of which they took the most enthusiastic advantage.

Another evening is here, and my friends have crept to bed with the exclamation, "how much we may live in a day." Bologna is unlike any other city we have ever seen, in a multitude of things. You walk all over it under arcades, sheltered on either side from the sun, the elegance and ornament of the lines of pillars depending on the wealth of the owner of the particular house, but columns and arches, simple or rich, everywhere. Imagine porticoes built on the front of every house in Philadelphia or New York, so as to cover the sidewalks completely, and, down the long perspective of every street, continued lines of airy Corinthian, or simple Doric pillars, and you may faintly conceive the impression of the streets of Bologna. With Lord Byron's desire to forget everything English, I do not wonder at his selection of this foreign city for a residence, so emphatically unlike, as it is, to everything else in the world.
