That it had a fascination for Oolanga goes without saying. He was never tired of visiting the museum in the tower, and spent endless hours in inspecting the exhibits, till he was thoroughly familiar with every detail of all of them. He asked permission to clean and polish and sharpen them--a favour which was readily granted. In addition to the above objects, there were many things of a kind to awaken human fear. Stuffed serpents of the most objectionable and horrid kind; giant insects from the tropics, fearsome in every detail; fishes and crustaceans covered with weird spikes; dried octopuses of great size. Other things, too, there were, not less deadly though seemingly innocuous--dried fungi, traps intended for birds, beasts, fishes, reptiles, and insects; machines which could produce pain of any kind and degree, and the only mercy of which was the power of producing speedy death. Caswall, who had never before seen any of these things, except those which he had collected himself, found a constant amusement and interest in them. He studied them, their uses, their mechanism--where there was such--and their places of origin, until he had an ample and real knowledge of all concerning them. Many were secret and intricate, but he never rested till he found out all the secrets. When once he had become interested in strange objects, and the way to use them, he began to explore various likely places for similar finds. He began to inquire of his household where strange lumber was kept. Several of the men spoke of old Simon Chester as one who knew everything in and about the house. Accordingly, he sent for the old man, who came at once. He was very old, nearly ninety years of age, and very infirm. He had been born in the Castle, and had served its succession of masters--present or absent--ever since. When Edgar began to question him on the subject regarding which he had sent for him, old Simon exhibited much perturbation. In fact, he became so frightened that his master, fully believing that he was concealing something, ordered him to tell at once what remained unseen, and where it was hidden away. Face to face with discovery of his secret, the old man, in a pitiable state of concern, spoke out even more fully than Mr. Caswall had expected. "Indeed, indeed, sir, everything is here in the tower that has ever been put away in my time except--except--" here he began to shake and tremble it--"except the chest which Mr. Edgar--he who was Mr. Edgar when I first took service--brought back from France, after he had been with Dr. Mesmer. The trunk has been kept in my room for safety; but I shall send it down here now." "What is in it?" asked Edgar sharply. "That I do not know. Moreover, it is a peculiar trunk, without any visible means of opening." "Is there no lock?" "I suppose so, sir; but I do not know. There is no keyhole." "Send it here; and then come to me yourself."
