In Cantal at Roqueville are the remains of a castle excavated out of the rocks. Between Jung-Bunzlau and Böhm-Leipa in Bohemia is the rock- castle of Habichstein. Two lakes lie in a basin of the hills that are well-wooded up their sides, but have bare turfy crowns. The upper lake is studded with islands. Between this and the lower lake stands an extraordinary hump of sandstone, on a sloping _talus_. This hump has much resemblance to a Noah's Ark stranded on a diminutive Ararat. The rock is perforated in all directions with galleries and chambers, and contains a stable for horses and for cattle, which, however, is no longer accessible. On the summit of the rock rises a keep very much resembling a Pictish broch. Habichstein belongs to the Wallenstein family that possesses a stately schloss at the head of the upper lake. It has been abandoned for, probably, two hundred years, as it can never have been a comfortable residence; moreover, the sandstone is continually breaking away. Below the hill and castle is the village. In 1811 there was a fall of the rock, and again in 1815, when it crushed three of the houses beneath. [ILLUSTRATION: THE PUXER LOCH, STYRIA. Supposed to have been occupied by a shadowless man. It was still inhabited last century by an old mason.] Another and still more curious cliff castle in Bohemia is that of Burgstein. There are several on the frontier of the Wargau and the Hardt in North Bohemia, where the German and Czech languages meet, but it is not possible here to describe them all. Burgstein is the most curious. It consists of an isolated mass of sandstone springing out of level land, an outlying block of the Schwoik chain. Formerly it rose out of a lake or marsh, but this is now drained. The entrance is through a narrow gap in the rock by a flight of steps that lead into a court on all sides surrounded by sheer precipices except towards the North-west, where a gap was closed by a wall. Out of this court open caves, one was formerly the smithy, another the guard-room, a third the stable, and in a recess is the well. From the court access to the main structure is obtained by a rift in the sandstone commanded by the guard-room, and up which ascends a stair of 15 steps that leads to a second rift at right angles, up which leads a further stair of 76 steps, and from the landing 37 descend to a lower portion of the rock, a platform with a breastwork of wall, important for defence of the entrance.
