CHAPTER I.

THE FIRST RETREAT.

Many winters, as we are told by the old men of the district, have passed since human beings first settled in the land of Ohet, a somewhat extensive valley of varying breadth, traversed by a winding stream running southward till it flows into a great river.

The sides of the valley present a series of hills of moderate height, descending by gentle slopes where it widens, and more abruptly where it narrows. On the steeper hill-sides grey crags jut out, and the ground is strewn with fragments of rock. Ascending the stream for some three hours' walk from the point where it joins the great river, we find on the right another stream separating into several small branches in a more elevated valley. In summer, some of these branches dry up, others form pools, whose banks are covered with reeds and water-lilies. The inhabitants of the vale dread this valley, which they believe to be haunted by evil spirits. It is dangerous to wander there, because of the number of bogs covered over with leaves and decaying branches in which the unwary sink. The forest in this valley is so dense, the plants and bushes are so thickly interlaced with the trunks and branches of dead trees, that the rays of the sun hardly penetrate through it, and only illuminate pools of water covered with a mantle of green. A kind of promontory divides the two water-courses at this point (Frontispiece—[Fig. 1)];—the river running from the north-west, and the smaller stream from the north-north-east. This elevated part of the country is covered with thick woods, and the inhabitants of the valley seldom go there except to hunt the wild ox, the boar, the wolf, and the deer. Beyond, the country seems a wilderness; and strangers who occasionally visit the inhabitants of the vale to exchange amber, copper, gold, salt, and coarse woollen or hempen fabrics for skins of beasts, never come except by the way where flows the great river. The occupants live in families, in the open spaces amid the woods and on the banks of the rivers, inhabiting conical huts, made with stakes set in the ground, joined at the top, and covered with branches, earth, and rushes. The father of the family occupies one of these huts with his wife and children, and as his sons grow up, they build another cabin and take a companion.

The products of the chase and fishing, with the wild roots which they dry and crush between stones, are their only means of subsistence; they do not till the soil, nor have they any flocks or herds. Our informants add that they never had to fight men like themselves, and that if any disputes arise between the families, they call together the oldest chiefs of the other families to arbitrate between them. Those who are unwilling to submit to their judgment are banished from the valley, together with their families; they descend the shores of the great river, and are no more heard of.

When these old men are further asked whether there were other human beings before them settled in the valley, they answer that there were; but that they were small men—dwarfs—who ate earth, and had no bows and arrows to kill the wild beasts, nor hooks to catch fish, nor canoes to cross the river; that at the approach of the present inhabitants, these dwarfs disappeared, and took refuge underground, whence they came out sometimes in the night to do mischief—to cut the fastenings of boats, or sink the boats themselves—to cause children at the breast to die, or to break the bows, or warn the animals of the forest of an intended chase, so that they might get out of the way.
