Satisfied that there must be some means of acting upon the concealed mechanism connected with the door, she ran her hands over the inside, and pressed every square inch with her fingers, in the hope of touching something which would set in action the secret spring. This manipulation producing no result, she next treaded the floor near the door in the same manner, but still without making any discovery. It then occurred to her that the spring might be situated above her reach, and instantly mounting upon the wicker basket which Blodget had brought her, she felt over the upper part of the door, and the wall around and above it as far as she could reach. An indescribable emotion of joy and hope thrilled through her bosom, as her fingers all at once encountered a small knob or button, about six feet from the floor, which yielded to the pressure, and acting on some concealed mechanism, caused the heavy door to revolve slowly and noiselessly upon its hinges. Stepping from the basket, she peered into the semi-obscurity of the lobby upon which the door opened, and discovering an ascending flight of stairs, she felt half inclined to venture up them; but on reflection, she thought such a step would be imprudent, and satisfied with possessing the means of opening the door at pleasure, she closed it to reflect, at leisure, upon the way in which she should make her discovery available for the purpose of escape. The impression that the door which she had discovered was not the one by which she had been borne into the chamber by her abductor still lingering in her mind, she resolved to examine the opposite wall in the same manner; and, setting the basket against the wall, she stood upon it as before, and passed her hand over the wall in every direction. To her great joy she was not long in discovering a knob similar to that which communicated with the secret spring of the other door, and pressing upon it, a door opened like the one by which Blodget had entered, and the rush of cold air which fanned her cheek, and the continued darkness, called to her mind the recollection of the subterraneans through which she had been borne the preceding night.
