He crossed the oak-panelled hall (where the essence of mediaeval England lingered) and came to the threshold of the conservatory. It was a scene confusedly beautiful. The air, as it touched his face, was tropically warm and indolent with voluptuous fragrance of flowers and plants. Luxuriant shrubs, with broad-drooping leaves, stood motionless in the heat. Two palm-trees uplifted their heavy plumes forty feet aloft, on slender stalks, brushing the high glass roof. In the midst of the conservatory a pool slumbered between rocky margins, overgrown with a profusion of reeds, grasses, and water-plants. There floated the giant leaves and blossoms of the tropic water-lily; and on a fragment of rock rising above the surface dozed a small crocodile, not more than four feet long, but looking as old, dried up, and coldly cruel as sin itself! The place looked like an Indian jungle, and Balder half expected to see the glancing spits of a tiger crouching beneath the overarching leaves; or a naked savage with bow and arrows. But amid all this vegetable luxuriance appeared no human being,--no animal save the evil crocodile. Whence, then, that melodious voice,--clear essence of nature's sweetest utterances? At the left of the conservatory was a door, the entrance to the Egyptian temple. It was square and heavy-browed, flanked by short thick columns rising from a base of sculptured papyrus-leaves, and flowering in lotus capitals. Three marble steps led to the threshold, while on either side reclined a sphinx in polished granite, softened, however, by a delicate flowering vine, which had been trained to cling round their necks. On the deep panels of the door were mystic emblems carved in relief. A line of hieroglyphics inscribed the lintel in deep blue, red, and black,--to what purport Balder could not divine. At the opposite side of the conservatory was a corresponding door, veiled by an ample fold of silken tapestry, cunningly hand-worked in representation of a moon half veiled in clouds, shining athwart a stormy sea. By her light a laboring ship was warned off the rocks to leeward. The room (one of the later additions) by its external promise might have been the bower of some fashionable beauty thousands of years ago. Balder looked from one of these doors to the other, doubting at which to apply. The tapestry curtain was swept aside at the base, leaving a small passage clear to the room beyond. In this opening now appeared the bright-crested head and eyes of the hoopoe, peeping mischievously at the intruder, who forthwith stepped down into the conservatory, holding forth to the little bird a friendly finger. The bird eyed him critically, then launched itself on the air, and, alighting on a spray above his head, warbled out a brilliant call.
