Our favorite walk is on the downs. George seems really penetrated with the uncommon beauty of the region, and wants to stop as long as possible, and does not believe any thing can be more beautiful. We look over the awful cliffs--gaze on the thread of water winding its devious course at an immense distance below--watch the steamers from Wales and Ireland shoot up to the city, and the noble West Indiamen, as they are towed along. The woods opposite are charming, and contain nearly every forest-tree belonging to the country. Dr. Holland, in his travels through Greece, refers to this very spot in the following language: "The features of nature are often best described by comparison; and to those who have visited Vincent's Rocks, below Bristol, I cannot convey a more sufficient idea of the far-famed Vale of Tempe than by saying that its scenery resembles, though on a much larger scale, that of the former place. The Peneus, indeed, as it flows through the valley, is not greatly wider than the Avon, and the channel between the cliffs irregularly contracted in its dimensions; but these cliffs themselves are much loftier and more precipitous, and project their vast masses of rock with still more extraordinary abruptness over the hollow beneath." We devoted a morning to visit Leigh Court, the residence of Mr. Miles, a wealthy merchant and member in Parliament for Bristol. This is regarded as one of the finest residences in the west of England. The mansion has an Ionic portico, supported by massive columns. The great hall is very extensive. A double flight of steps leads you to a peristyle of the Ionic order, around which are twenty marble columns, supporting a lofty dome, lighted by painted glass. The floor is of colored marble. This residence has been enriched with the choicest treasures from Wanstead House, and Fonthill Abbey. To us the grand attraction was the Picture Gallery, which has few superiors in the kingdom. A catalogue, with etchings, was published a few years ago. You may judge of the merits of the collection, and the nature of our gratification, when I tell you that here are the Conversion of Paul, by Rubens; the Graces, by Titian; William Tell, by Holbein; Pope Julius II., by Raphael; Ecce Homo, by Carl Dolci; Head of the Virgin, by Correggio; St. Peter, by Guido; St. John, by Domenichino; Creator Mundi, by Leonardo da Vinci; Crucifixion, by Michael Angelo; Plague of Athens, by N. Poussin; three Seaports, by Claude; and a large number by Rembrandt, Salvator Rosa, Paul Potter, Parmegiano, Velasques, Gerard Dow, &c. This has been a most gratifying excursion, and our visit here will be a matter of pleasant recollection. I forgot to say that at Clifton, and at various places near the rocks, we were beset by men, women, and children, having very beautiful polished specimens of the various stones found in the quarries, together with minerals and petrifactions. Of these we all obtained an assortment.
