Soon after the unfurling of the standard, we find the Marquis of Tullibardine writing to Mrs. Robertson of Lude, a daughter of Lord Nairn, and desiring her to put the Castle of Blair into some order, and to do honours of the place when the Prince should come there. The Marquis, it is here proper to mention, was regarded by all the Jacobites as still the head of his house, and uniformly styled by that party the "Duke of Athole," yet he seldom adopted the title himself; and in only one or two instances in his correspondence does the signature of Athole occur.[55] On the thirty-first of August the Prince visited the famous Blair Athole, or Field of Athole, the word _Blair_ signifying a pleasant land, and being descriptive of that beautiful vale situated in the midst of wild and mountainous scenery. After riding along a black moor, in sight of vast mountains, the castle, a plain massive white house, appears in view. It is seated on an eminence above a plain watered by the Gary, called, by Pennant, "an outrageous stream, which laves and rushes along vast beds of gravel on the valley below." The approach to Blair Castle winds up a very steep and high hill, and through a great birch wood, forming a most picturesque scene, from the pendent form of the boughs waving with the wind from the bottom to the utmost summits of the mountains. On attaining the top, a view of the beautiful little Straith, fertile and wooded, with the river in the middle, delights the beholder. The stream, after meandering in various circles, suddenly swells into a lake that fills the vale from side to side; this lake is about three miles long, and retains the name of the river. When Prince Charles visited Blair, it was a fortified house, and capable of holding out a siege afterwards against his adherents. Its height was consequently lowered, but the inside has been finished with care by the ducal owner. The environs of this beautiful place are thus described by the graphic pen of Pennant,[56] whose description of them, having been written in 1769, is more likely to apply to the state in which it was when Prince Charles beheld it, than that of any more modern traveller. "The Duke of Athoel's estate is very extensive, and the country populous; while vassalage existed, the chieftain could raise two or three thousand fighting-men, and leave sufficient at home to take care of the ground. The forests, or rather chases, (for they are quite naked,) are very extensive, and feed vast numbers of stags, which range at certain times of the year in herds of five hundred. Some grow to a great size. The hunting of these animals was formerly after the manner of an Eastern monarch. Thousands of vassals surrounded a great tract of country, and drove the deer to the spot where the chieftains were stationed, who shot them at their leisure.
