Some three or four miles east from Bala, the Berwyn Mountains raise their heathery summits in the midst of a solitude broken only by the plaintive bleat of a lost sheep or the shouts of men in search of it.

For miles the purple moorland rolls on without a moving creature to break the stillness. Deep ravines run down on either hand through green, ferny sheep-walks, dotted with innumerable sheep. These ravines in winter time, when the snow lies deep on the hills, are, when not frost-bound, roaring torrents. In the summer, huge blocks of stone are scattered about in strange confusion, and a tiny stream can scarcely find its way between them. Lower down still can be seen, here and there, a farm-house, in some sheltered glen, kept green all the year round by the trickling moisture. Further off still, in the valleys, are villages and hamlets tenanted by hardy Welsh sheep-farmers and dealers.

In the least-exposed corners of the sheep-walks are folds built of loose, unmortared stones, in which the sheep huddle to find shelter from the fury of the frequent storms which sweep over the mountains.

As the wealth of the hill farmers consists chiefly of sheep, if a dog once takes to worrying them, he is either kept in durance vile, or killed. The habit once acquired is never got rid of; and after a sheep-dog has once tasted blood, it becomes practically useless to the farmer. The quantity of sheep that can be killed by such a dog in a short time is almost incredible.

It may be imagined, therefore, with what feelings the Berwyn farmers heard of sheep after sheep being killed on their own and neighbouring farms, by a dog which nobody owned, and which ran loose on the mountains catering for itself. Descending from the lonelier parts of the hills, it would visit the sheep-walks and kill, as it appeared, for the pure love of killing; in most cases leaving the mangled bodies on the spot.

Month after month ran by, and it still eluded the vengeance of the indignant hillmen. The most exaggerated accounts were current respecting its size and ferocity. No two versions agreed as to its colour, though all gave it enormous size. As it afterwards turned out, it was a black and white foxhound bitch.

Everybody carried a gun, but on the few occasions that the dog came within shot, it appeared to be shot proof. The loss of numerous sheep was becoming serious; in some instances the farmers suffered heavily. It was the staple topic of conversation. From time to time, paragraphs, such as the following, appeared in the papers published in the neighbouring towns:—

"The Rapacious Dog.—The noted sheep destroyer on the Berwyn hills still continues to commit his depredations, in spite of all efforts to kill him.

"The last that was seen of him was on Sunday morning, by Mr Jones on the Syria sheep-walk, when the dog was in the act of killing a lamb. Mr Jones was armed with a gun at the time, and tried to get within gunshot range; but it seems that the animal can scent a man approaching him from a long distance, so he made off immediately. After it became known to the farmers and inhabitants of Llandrillo that he had been seen, a large party went up to the mountain at once, and were on the hills all day, but nothing more was heard of him till late in the evening, when he was again seen on Hendwr sheep-walk, and again entirely lost. On Monday a number of foxhounds were expected from Tanybwlch, and if a sight of him can be obtained, no doubt he will be hunted down and captured, and receive what he is fully entitled to—capital punishment."

On a bright May morning, five months after the first appearance of the sheep-destroyer, a pack, consisting of a dozen couple of fox-dogs, with their huntsman, started up the lane from Llandderfel to the hills, followed by a motley crowd of farmers and labourers, armed with guns and sticks, and numbering many horsemen.
