"Excellent!" exclaimed her brother. "Come, Art, let's hang a bell in the kitchen and attach a string to it, taking the other end up to the observatory." The suggestion was immediately carried out. It had been previously arranged that the two young men should repair to the observatory, and there watch for the coming of the foe, and on their first appearance, probably a mile or more distant, give the alarm to those below, by pulling a wire attached to that from which the front door bell was suspended; thus setting it to ringing loudly. Now they were prepared to sound the tocsin in the kitchen, also, thus giving time for the removal of the boiling lye from the fire there to the second story of the mansion, where it was to be used according to Uncle Joe's plan. The detective had reported the assailing party as numbering from thirty-five to forty; but the Ion force, though much inferior in point of numbers, even with the addition of eight or ten negro men belonging to the Oaks and Ion, who were tolerably proficient in the use of firearms, certainly had the advantage of position, and of being on the side of right and justice. The gentlemen seemed full of a cheerful courage, the ladies calm and hopeful. Yet they refused to retire, though strongly urged to do so, insisting that to sleep would be simply impossible. It was but ten o'clock when all was ready, yet the young men deemed it most prudent to betake themselves at once to their outlook, since there might possibly have been some change in the plans of the enemy. The others gathered in one of the lower rooms to while away the tedious time of waiting as best they could. Conversation flagged; they tried music, but it had lost its charms for the time being; they turned away from the piano and harp and sank into silence; the house seemed strangely silent, and the pattering of Bruno's feet as he passed slowly down the whole length of the corridor without, came to their ears with almost startling distinctness. Then he appeared in the doorway, where he stood turning his eyes from one to another with a wistful, questioning gaze: then words seemed to come from his lips in tones of wonder and inquiry. "What are you all doing here at this time o' night, when honest folk should be a-bed?" "Just what I've been asking myself for the last hour," gravely remarked a statue in a niche in the opposite wall. The effect was startling even to those who understood the thing; more so to the others, Rosie screamed and ran to her father for protection. "Why, why, why!" cried old Mr. Dinsmore, in momentary perplexity and astonishment. "Don't be afraid Miss Rosie; I'm a faithful friend, and the woman over there couldn't hurt you if she would," said Bruno, going up to the young girl, wagging his tail and touching his cold nose to her hand. She drew it away with another scream. "Dear child," said her sister, "it is only a trick of ventriloquism." "Meant to amuse, not alarm," added Mr. Lilburn.
