imitation, strike the other on the shoulder, and point toward them. They then made their obeisance to the airy phantoms, which was instantly returned. They waved their hats and umbrellas, and the shadowy figures did the same. Like other travelers, they had carried with them a bottle of usquebaugh, and amused themselves in drinking to the figures, which was of course duly returned. In short, every movement which they made, they could observe distinctly repeated by the figures in the cloud. The appearance continued about a quarter of an hour. A gentle breeze from the north carried the cloud slowly away; the figures became less and less distinct, and at last vanished. North of the village of Comrie, in Perthshire, there is a bold hill called Dunmore, with a pillar of seventy or eighty feet in height built on its summit in memory of the late Lord Melville. At about eight o’clock of the evening of the 21st of August, of the year 1845, a perfect image of this well-known hill and obelisk, as exact as the shadow usually represents the substance, was distinctly observed projecting on the northern sky, at least two miles beyond the original, which, owing to an intervening eminence, was not itself at all in view from the station where the aerial picture was observed. The figure continued visible for about ten minutes after it was first seen, and was minutely examined by three individuals. One of these fancied that there was a projection at the base of the monument, as represented in the air, which was not in the original; but, upon examining the latter the next morning, the image was found to have been more faithful than his memory; for there stood the prototype of the projection, in the shape of a clump of trees, at the base of the real obelisk.
