At the end of the first week he was taken down with a disconcerting suspicion that the Baron had made a fool of him. He was filled with a wrath that had to be cooled. One morning, just as he was leaving his apartment, he saw two milk cans filled with milk standing in the outer hall. One was for the first floor, the other for the second. The milkmaid had placed them there for the time being, and had gone over to have a little morning chat with her neighbour. Herr Carovius went to his lumber-room, which also served as the kitchen, took down a jug of vinegar, came back, looked around with all the caution he could summon, and then poured half of the contents of the jug into one can and the other half into the other.
Two days later he decided not to give Cæsar anything to eat, so that he would terrify the neighbours by his howling. This worked. The dog howled and whined and barked night after night. It was enough to melt the heart of a stone. Nobody could sleep. Andreas Döderlein went to the police, but they told him that the case was beyond their jurisdiction.
Herr Carovius lay in bed rejoicing with exceeding great joy over the fact that the people could not sleep. He became enamoured of the idea that it might be possible, through some ingenious invention, to rob a whole city or a whole nation of its sleep. The inventor could then move about conscious of the fact that he was at once the distributor and the destroyer of the world's supply of sleep. If he so elected to exploit his invention, he could revel in the sight of an entire people pining, drying up, and eventually dying from the want of sleep.
After Cæsar had become quite savage, Herr Carovius decided to unleash him. It was just after sunset. He slipped up to the beast from the rear, and opened the chain lock. The dog ran like mad through the court and the hall, and out on to the street.
Just at this moment young Baron von Auffenberg was entering to pay Herr Carovius that promised visit. He jumped back from the beast, but it sprang at his body, and in a jiffy the Baron was lying full length on the pavement. Cæsar left him, made a straight line for the open door of a butcher shop across the street, sprang in, and snatched a fancy cut from one of the hooks.
