For the first thirty, or in parts, fifty miles from the Mountains, Silesia slopes somewhat rapidly; and is still to be called a Hill-country, rugged extensive elevations diversifying it: but after that, the slope is gentle, and at length insensible, or noticeable only by the way the waters run. From the central part of it, Schlesien pictures itself to you as a plain; growing ever flatter, ever sandier, as it abuts on the monotonous endless sand-flats of Poland, and the Brandenburg territories; nothing but Boundary Stones with their brass inscriptions marking where the transition is; and only some Fortified Town, not far off, keeping the door of the Country secure in that quarter. On the other hand, the Mountain part of Schlesien is very picturesque; not of Alpine height anywhere (the Schnee-Koppe itself is under 5,000 feet), so that verdure and forest wood fail almost nowhere among the Mountains; and multiplex industry, besung by rushing torrents and the swift young rivers, nestles itself high up; and from wheat husbandry, madder and maize husbandry, to damask-weaving, metallurgy, charcoal-burning, tar-distillery, Schlesien has many trades, and has long been expert and busy at them to a high degree. A very pretty Ellipsis, or irregular Oval, on the summit of the European Continent;--"like the palm of a left hand well stretched out, with the Riesengebirge for thumb!" said a certain Herr to me, stretching out his arm in that fashion towards the northwest. Palm, well stretched out, measuring 250 miles; and the crossway 100. There are still beavers in Schlesien; the Katzbach River has gold grains in it, a kind of Pactolus not now worth working; and in the scraggy lonesome pine-woods, grimy individuals, with kindled mounds of pine-branches and smoke carefully kept down by sods, are sweating out a substance which they inform you is to be tar.
