There can be no question, however, that being then very young, Glengyle must have acted on most occasions by the advice and direction of so experienced a leader as his uncle.

The MacGregors assembled in numbers at that period, and began even to threaten the Lowlands towards the lower extremity of Loch Lomond. They suddenly seized all the boats which were upon the lake, and, probably with a view to some enterprise of their own, drew them overland to Inversnaid, in order to intercept the progress of a large body of west-country whigs who were in arms for the government, and moving in that direction.

The whigs made an excursion for the recovery of the boats. Their forces consisted of volunteers from Paisley, Kilpatrick, and elsewhere, who, with the assistance of a body of seamen, were towed up the river Leven in long-boats belonging to the ships of war then lying in the Clyde. At Luss they were joined by the forces of Sir Humphrey Colquhoun, and James Grant, his son-in-law, with their followers, attired in the Highland dress of the period, which is picturesquely described.* The whole party crossed to Craig-Royston, but the MacGregors did not offer combat.

* "At night they arrived at Luss, where they were joined by Sir Humphrey Colquhoun of Luss, and James Grant of Plascander, his son-in-law, followed by forty or fifty stately fellows in their short hose and belted plaids, armed each of them with a well-fixed gun on his shoulder, a strong handsome target, with a sharp-pointed steel of above half an ell in length screwed into the navel of it, on his left arm, a sturdy claymore by his side, and a pistol or two, with a dirk and knife, in his belt."—Rae's History of the Rebellion, 4to, p. 287.

If we are to believe the account of the expedition given by the historian Rae, they leapt on shore at Craig-Royston with the utmost intrepidity, no enemy appearing to oppose them, and by the noise of their drums, which they beat incessantly, and the discharge of their artillery and small arms, terrified the MacGregors, whom they appear never to have seen, out of their fastnesses, and caused them to fly in a panic to the general camp of the Highlanders at Strath-Fillan.* The low-country men succeeded in getting possession of the boats at a great expenditure of noise and courage, and little risk of danger.

After this temporary removal from his old haunts, Rob Roy was sent by the Earl of Mar to Aberdeen, to raise, it is believed, a part of the clan Gregor, which is settled in that country. These men were of his own family (the race of the Ciar Mhor). They were the descendants of about three hundred MacGregors whom the Earl of Murray, about the year 1624, transported from his estates in Menteith to oppose against his enemies the MacIntoshes, a race as hardy and restless as they were themselves.

But while in the city of Aberdeen, Rob Roy met a relation of a very different class and character from those whom he was sent to summon to arms. This was Dr. James Gregory (by descent a MacGregor), the patriarch of a dynasty of professors distinguished for literary and scientific talent, and the grandfather of the late eminent physician and accomplished scholar, Professor Gregory of Edinburgh. This gentleman was at the time Professor of Medicine in King's College, Aberdeen, and son of Dr. James Gregory, distinguished in science as the inventor of the reflecting telescope. With such a family it may seem our friend Rob could have had little communion. But civil war is a species of misery which introduces men to strange bed-fellows. Dr. Gregory thought it a point of prudence to claim kindred, at so critical a period, with a man so formidable and influential. He invited Rob Roy to his house, and treated him with so much kindness, that he produced in his generous bosom a degree of gratitude which seemed likely to occasion very inconvenient effects.

The Professor had a son about eight or nine years old,—a lively, stout boy of his age,—with whose appearance our Highland Robin Hood was much taken. On the day before his departure from the house of his learned relative, Rob Roy, who had pondered deeply how he might requite his cousin's kindness, took Dr. Gregory aside, and addressed him to this purport:—"My dear kinsman, I have been thinking what I could do to show my sense of your hospitality. Now, here you have a fine spirited boy of a son, whom you are ruining by cramming him with your useless book-learning, and I am determined, by way of manifesting my great good-will to you and yours, to take him with me and make a man of him." The learned Professor was utterly overwhelmed when his warlike kinsman announced his kind purpose in language which implied no doubt of its being a proposal which, would be, and ought to be, accepted with the utmost gratitude. The task of apology or explanation was of a most delicate description; and there might have been considerable danger in suffering Rob Roy to perceive that the promotion with which he threatened the son was, in the father's eyes, the ready road to the gallows. Indeed, every excuse which he could at first think of—such as regret for putting his friend to trouble with a youth who had been educated in the Lowlands, and so on—only strengthened the chieftain's inclination to patronise his young kinsman, as he supposed they arose entirely from the modesty of the father. He would for a long time take no apology, and even spoke of carrying off the youth by a certain degree of kindly violence, whether his father consented, or not. At length the perplexed Professor pleaded that his son was very young, and in an infirm state of health, and not yet able to endure the hardships of a mountain life; but that in another year or two he hoped his health would be firmly established, and he would be in a fitting condition to attend on his brave kinsman, and follow out the splendid destinies to which he opened the way. This agreement being made, the cousins parted,—Rob Roy pledging his honour to carry his young relation to the hills with him on his next return to Aberdeenshire, and Dr. Gregory, doubtless, praying in his secret soul that he might never see Rob's Highland face again.

James Gregory, who thus escaped being his kinsman's recruit, and in all probability his henchman, was afterwards Professor of Medicine in the College, and, like most of his family, distinguished by his scientific acquirements. He was rather of an irritable and pertinacious disposition; and his friends were wont to remark, when he showed any symptom of these foibles, "Ah! this comes of not having been educated by Rob Roy."

The connection between Rob Roy and his classical kinsman did not end with the period of Rob's transient power. At a period considerably subsequent to the year 1715, he was walking in the Castle Street of Aberdeen, arm in arm with his host, Dr. James Gregory, when the drums in the barracks suddenly beat to arms, and soldiers were seen issuing from the barracks. "If these lads are turning out," said Rob, taking leave of his cousin with great composure, "it is time for me to look after my safety." So saying, he dived down a close, and, as John Bunyan says, "went upon his way and was seen no more."*

* The first of these anecdotes, which brings the highest pitch of civilisation so closely in contact with the half-savage state of society, I have heard told by the late distinguished Dr. Gregory; and the members of his family have had the kindness to collate the story with their recollections and family documents, and furnish the authentic particulars.
