And Dorothy sat as it were at the spring-head of the waters, for, through her dominion over the fire-engine, she had become the naiad of Raglan. The same hour in which lord Herbert departed she went to Kaltoff, and was by him instructed in its mysteries. On the third day after, so entirely was the Dutchman satisfied with her understanding and management of it, that he gave up to her the whole water-business. And now, as I say, she sat at the source of all the streams and fountains of the place, and governed them all. The horse of marble spouted and ceased at her will, but in general she let the stream from his mouth flow all day long. Every water-cock on the great tower was subject to her. From the urn of her pleasure the cistern was daily filled, and from the summit of defence her flood went pouring into the moat around its feet, until it mantled to the brim, turning the weeds into a cold shadowy pavement of green for a foil to its pellucid depth. She understood all the secrets of the aqueous catapult, at which its contriver had little more than hinted on that memorable night when he disclosed so much, and believed she could arrange it for action without assistance. At the same time her new responsibilities required but a portion of her leisure, and lady Margaret was not the less pleased with the wise-headed girl, whose manners and mental ways were such a contrast to her own, that her husband considered her fit to be put in charge of his darling invention. But Dorothy kept silence concerning the trust to all but her mistress, who, on her part, was prudent enough to avoid any allusion which might raise yet higher the jealousy of her associates, by whom she was already regarded as supplanting them in the favour of their mistress. One lovely evening in May, the moon at the full, the air warm yet fresh, the apple-blossoms at their largest, with as yet no spot upon their fair skin, and the nightingales singing out of their very bones, the season, the hour, the blossoms, and the moon had invaded every chamber in the castle, seized every heart of both man and beast, and turned all into one congregation of which the nightingales were the priests. The cocks were crowing as if it had been the dawn itself instead of its ghost they saw; the dogs were howling, but whether that was from love or hate of the moon, I cannot tell; the pigeons were cooing; the peacock had turned his train into a paralune, understanding well that the carnival could not be complete without him and his; and the wild beasts were restless, uttering a short yell now and then, at least aware that something was going on. All the inhabitants of the castle were out of doors, the ladies and gentlemen in groups here and there about the gardens and lawns and islands, and the domestics, and such of the garrison as were not on duty, wandering hither and thither where they pleased, careful only not to intrude on their superiors.
