"Halt, Alaster," said Rob, interposing; "were this a question about a drove of sheep you might know something; but as the matter concerns the leading of armed men, you must allow me to judge."

"Were the question about the foraying of a drove of Glen Eigas stots, the question with you, Rob, would not be who should be last, but who should be first," was the stinging retort of MacPherson.

This nearly produced a quarrel between them; already their brows were knitted and their swords menaced each other, even while shells were bursting and shot of every kind were tearing up the turf about them; but finding the inexpedience of coming to blows when under the fire of an enemy, they gave each other a grim smile, and exchanged their snuff-mulls in token of amity, yet many of their men now joined the MacLeans, who at this moment made a tremendous charge upon the regulars.

The appearance of this clan in the field, numbering 800 swordsmen, is a memorable instance of the power of the patriarchal system over the feudal.

The chief had lived for years a banished loyalist in France, and their lands in Mull had been gifted to the House of Argyle; yet, in opposition to the latter, the whole fighting force of the clan were in the field against the duke, their legal landlord, and under their long-exiled chief, the venerable Sir John MacLean, fought valiantly.

With the best born, the best armed, and the bravest of the Clan Gillian in front, he led them on three ranks deep.

"Gentlemen," he exclaimed, "this is the day we have long wished for. Yonder stands Argyle for King George; here stands MacLean for King James! God bless him! Charge, gentlemen, charge!"

And with a wild yell, in which their pibroch mingled, the clan rushed on, and the levelled bayonets of the soldiers of the line went down before their whirling swords, like straw before the flames.

At that moment, through the smoke of the action there rushed an English officer towards the MacGregor's line. His sword was broken in his hand, and left him at the mercy of a gigantic Highlander, who pursued him with a tuagh, or Lochaber axe. He was bareheaded also, having lost his hat.

A stone caught the foot of this fugitive, who fell almost at the feet of Rob Roy. With a shout of triumph the fierce pursuer uplifted his axe, and was about to cleave the defenceless head of the Englishman, when the stroke was arrested by the interposed shield of MacGregor.
