Like other groups of mountains, the highest and largest are those near the centre, and from them the land descends in lower and lower levels, with smaller hills and smoother valleys, until at length it sinks into the plain. Then they are almost like children's hills and valleys; the slopes are not too steep for very little feet to climb, and the rippling brooks are not in so much hurry to rush on to the distant river, but that boys and girls at play can stop them for a little time with slight banks of mud and stones. In just such a smooth, sloping dell, down in a soft green basin, called Fern's Hollow, was the hiding-place where the convict's sad wife had found an unmolested shelter. This dwelling, the second one raised by the returned convict and his son, is built just below the brow of the hill, so that the back of the hut is formed of the hill itself, and only the sides and front are real walls. These walls are made of rubble, or loose, unhewn stones, piled together with a kind of mortar, which is little more than clay baked hard in the heat of the sun. The chimney is a bit of old stove-pipe, scarcely rising above the top of the hill behind; and, but for the smoke, we could look down the pipe, as through the tube of a telescope, upon the family sitting round the hearth within. The thatch, overgrown with moss, appears as a continuation of the slope of the hill itself, and might almost deceive the simple sheep grazing around it. Instead of a window there is only a square hole, covered by a shutter when the light is not urgently needed; and the door is so much too small for its sill and lintels as to leave large chinks, through which adventurous bees and beetles may find their way within. You may see at a glance that there is but one room, and that there can be no up-stairs to the hut, except that upper storey of the broad, open common behind it, where the birds sleep softly in their cosy nests. Before the house is a garden; and beyond that a small field sown with silver oats, which are dancing and glistening in the breeze and sunshine; while before the garden wicket, but not enclosed from the common, is a warm, sunny valley, in the very middle of which a slender thread of a brook widens into a lovely little basin of a pool, clear and cold, the very place for the hill ponies to come and drink.
