"The country," says the visitor we have just quoted, "is not flat, but a gently waving one; yet, from above and afar, its inequalities of surface vanish into a map-like smoothness, and are traceable only in the light and shade cast by hill and plain. The prospect here has a diameter of near a hundred miles: its scope is therefore such that atmospheric effects are constantly flickering over it, even in the most cloudless days of a climate as bright if not quite so soft as that of Italy; and thus each varying aspect of the weather is reflected, all the while, from the features of the landscape, as the passions are over the face of some capricious beauty, that laughs, and frowns, and weeps almost in the same breath. Near you, perhaps, all is smiling in the sunlight; yonder broods or bursts a storm; while, in a third quarter, darkness and light contend upon the prospect, and chase each other. The sky itself is thus not more shifting than the scene you may have before you. It takes a new aspect at almost every moment, and bewitches you with a perpetual novelty." The mansion of the philosopher was placed on the top of an eminence commanding this beautiful scene. It was somewhat fantastic in its architecture, owing to the additions and rebuildings that had been constantly going on, to adapt it to the enlarged wants and changing tastes of the occupant, but it was spacious, richly furnished and commodious. The rarest treasures of literature adorned the library, and indeed every part bore witness to the affluence and cultivated pursuits of the venerable sage. A farm of some fourteen thousand acres lay about among the hills, which was laboriously and carefully husbanded, and which gave employment in various ways to a number of artificers and mechanics, whose dwellings were distributed about the slopes. His estate, in short, was a small and almost independent community in itself, capable of supplying the ordinary needs and even the luxuries of a highly civilized condition of social existence. As a proof of this, we may state by the way, that the carriage of the proprietor, as well as many of the tools and implements in daily use, had been manufactured on the premises. But the wonder of the place was the library, which was not only extensive, but extensively rich in its rare possessions, which the master had seduously collected during his long residence abroad from every nook and corner of Europe. Unfortunately many of these books, afterwards presented to Congress, were burned in the conflagration of the Capitol. Of the man himself, a guest, who was any thing but an admirer, has left this record.
