Miraculous escape--Another of those distressing accidents which too often lead to a melancholy catastrophe took place on Wednesday evening last. A party of four adventurous gentlemen, who had resolved on visiting the Theatre Royal, Drury Lane, after a quiet dinner at their club, proceeded to that edifice, and, under the direction of a guide, actually penetrated the labyrinths to the lowest box on the opposite side from that at which they entered. Having achieved this feat, and feasted their eyes upon the scenery thus set before them, one of them announced his intention of attempting to get out of the theatre alone. His companions sought to dissuade him from this foolhardy exploit; but, flushed, it is supposed, with an extra half-pint of St. Estephe, the traveller, a remarkably fine young man, to whom his friends were not in the least attached, departed on the perilous enterprise. He ascended eleven staircases, descended fourteen, and, having gone backwards and forwards through twenty-two of the passages which come from nowhere and lead to nothing, in this most wonderfully constructed building, he made the appalling discovery that he had lost his way. With the true Anglo-Saxon courage, he continued to explore undauntedly, and at one period went down deep into the bowels of the earth, where, far above his head, he could distinctly hear the trampling of feet, and where, in the darkness, he stumbled upon certain whitish objects which may have been either the skeletons of other lost travellers, or else property busts and statues. At length, overcome by terror and thirst, he rushed upwards, and continued to mount until he reached the dizzy height where the air was so intensely rarified as to smell of oranges and gingerbeer, and where, he states, he could distinctly hear the voice of MR. GUSTAVUS BROOKE recommending MISS FEATHERSTONE to go to a nunnery. His sufferings at this period were most acute, and his despairing efforts to open every door he saw were agonizing.
