'What errand takes him to the Craig-na-tuirc to-night?' I remarked.

'The devil only knows: perhaps to see the desolation he has made, and whether any of our people have lit a fire in the glens below. There he goes—may evil follow, and destruction dog him close! may the curse of the poor on whom he tramples, and the scorn of the rich whom he worships, be his lot! I'll show them a flame on Ben Ora to-night that will startle all the Western Highlands!'

Callum drew forth his powder-horn, and after casting a keen but furtive glance around him in the dusk, and after seeing Mr. Snaggs fairly disappear in a hollow of the hills, he shook out the contents, laying across the narrow mouth of the glen a train on the soft dry heather and its bed of turf and decayed moss below. Careless of the event, and now resigned to whatever might follow, I observed him in moody silence, and not without feeling within me that longing for revenge which is so curiously mingled in the Celtic nature, with a wild sense of justice and of injury.

'This is a crime against the law,' said I, in a low voice, remembering that muirburning is a serious offence in Scotland, and that the Acts passed by the Parliaments of the first, third, fourth, and fifth Jameses concerning it, are alike stringent and severe.

'Curse upon the laws,' grumbled Callum; 'if none were made, they would never be violated,' and with these words he emptied the last contents of his horn. Again he looked round him.

The sun had set long since; the tints of the vast mountain had turned from purple to black, and no living thing seemed to be stirring in that intense solitude. Callum stooped, and fired his pistol at the train. The powder flashed, and rose like a fiery serpent along the grass; the dry summer-moss, the decayed leaves and dead ferns ignited like tinder, and in a moment the thick heath and its bed of turf and peat below were wrapped in smoke and flame—a flame that spread on every hand, deepening and extending, as it rolled, like a devouring and encroaching tide, mounting up the sides of the glen before the soft west wind that blew from the dark waves of the salt lake.

Fiercely it crackled, smouldered, and burned, in those places where the bracken or whins, the burr-docks, brambles, rank weeds, and gorse grew thick; but in others it rolled steadily on with great rapidity, spreading and widening in the form of a vast semi-circle, as if it would embrace the whole country in its grasp. As it mounted into the higher portions of the landscape, and seized on the thickets of silver birch and the resinous mountain-pine, the conflagration began to crackle, roar, and hiss, and its flames to shoot aloft and brighten against the sky like the wavering beams of the Northern Lights, tinging the clouds with pink and purple hues.

Now sheep and cattle, horses, rabbits, foxes, and fuimarts, with herds of frantic deer, fled before the flames; and screaming in their terror and confusion, the muirfowl flew hither and thither, or hung overhead among the vapour that shrouded the starry sky. The scene was strange, wild, and terrible; the more so that amid all this general alarm of nature there was not heard the voice of man in wonder or in fear; but the glens had been swept of their people, and the beasts of the field and the birds of the air alone remained.

With astonishment and somewhat of awe, I gazed on this strange and striking scene, while Callum Dhu surveyed it with a grim smile of triumph and derision on his weather-beaten face, which was reddened by the distant glow.

This was one of the most dreadful instances of muirburning that ever occurred in Scotland: the flames travelled at the rate of one hundred and fifty yards a minute, and soon embraced a front of nearly sixteen miles in length, being four miles more than that tide of fire which lately devoured the moors of Strathaven.
