Yonder is a fair street, extending north and south. The stately mansions are placed each on its carpet of verdant grass, and a long flight of steps descends from every door to the pavement. Ornamental trees—the broad-leafed horse-chestnut, the elm so lofty and bending, the graceful but infrequent willow. On its whole extent there is now but a single passenger, advancing from the upper end; and be, unless distance and the medium of a pocket spyglass do him more than justice, is a fine young man of twenty.
