It was on one of these moorland spots that the MacGregors halted. The eye could detect no living object in the distance, and the wind brought no sound to the ear, as by the great grey stone in the wilderness Rob and his men sat listening intently, and frequently with their ears close to the ground, conversing the while in their native Gaelic, which, though strange in sound and barbarous to English ears, is, like the Welsh, a strong, nervous, and poetical language, expressing the emotions of the human heart almost better than any other in Europe. His followers were beginning to lose heart; and fears that Colin's death might be unavenged and the cattle lost were freely expressed.

"Remember the oath we have sworn, and neither will come to pass," said Rob, with stern confidence. "By the soul of Ciar Mhor, and by all the bones that lie in the Island of the Cell, our swords shall cross theirs before another sunset, or my name is not MacGregor!"

"Four of the cattle are brown beasties of my own," observed Greumoch; "and if they should be lost, and Breadalbane does not see me righted, by St. Colme, I'll bring off the Spanish ram and the eight score of black-faced Galloways that are now in his park at Beallach, though every Campbell in Glenorchy puts his sword to the grindstone for it!"

"And I will back you, Greumoch, though Breadalbane is my own kinsman," said Rob Roy.

"We are Campbells by day, oich! oich!" said Greumoch, in a tone of singularly bitter irony, which drew muttered oaths from his companions; "but by night——"

"We are MacGregors like our fathers, and again the sons of Alpine!" said Rob, starting to his feet. "'S Rioghal mo dhream! Forward, lads! MacAleister shouts to us—the bloodhound has again got the scent."

The chieftain was right—the noble dog had discovered the trail; and once more the pursuit was resumed in a direction due north-west. As day broke, the distant hill-tops became yellow, and the wild moor gradually lightened around them. Rob and his followers had just doffed their bonnets, in reverence to the rising sun—a superstitious act, old as the days of Baal and the Druids—when a fox suddenly crossed their path.

"Shoot, MacAleister, shoot!" exclaimed a dozen voices in an excited manner, for the son of the arrow-maker was the best marksman on the shores of Loch Lomond.

"But the creagh—the caterans!" he urged, while unslinging his long Spanish gun.

"They cannot hear the shot, and, even if they did, the fox must not escape."
