He didn't consider it his business to utter a warning because the bump he expected happened almost immediately. He had misjudged the distance. Owing to the slow pace the impact was very slight, slighter even than Cosmo expected against such a heavy body as a mooring buoy would be. It was really more like a feeble hollow sound than a shock. Cosmo, who was prepared for it, was really the one that felt it at once, and the ancient boatman looked sharply over his shoulder. He uttered no sound and did not even attempt to rise from the thwart. He simply, as it seemed to Cosmo, let go the oars. The _sbirri_ only became aware of something having happened after the hollow bump was repeated, and Cosmo had become aware that the object on the water was not a buoy but another boat not much bigger than theirs. Then they both exclaimed and in their surprise their grip relaxed. One of them cried in astonishment, "An empty boat." It was indeed a surprising occurrence. With no particular purpose in his mind Cosmo stood up while one of the _sbirri_ stood up either to catch hold of the boat or push it away, for the two boats were alongside each other by that time. A strange voice in the dark said very loud: "The man in the hat," and as if by enchantment three figures appeared standing in a row. Cosmo had not even time to feel surprised. The two boats started knocking about considerably, and he felt himself seized by the collar and one arm and dragged away violently from between the two _sbirri_ by the power of irresistible arms which as suddenly let him go as if he were an inanimate object, and he fell heavily in the bottom of the second boat almost before his legs were altogether clear of the other. During this violent translation his hat fell off his head without any scheming on his part. He was not exactly frightened but he was excusably flustered. One is not kidnapped like this without any preliminaries every day. He was painfully aware of being in the way of his new captors. He was kicked in the ribs and his legs were trodden upon. He heard blows being struck against hard substances which he knew were human skulls because of the abortive yells ending in groans. There was a determination and ferocity in this attack combined with the least possible amount of noise. All he could hear were the heavy blows and the hard breathing of the assailants. Then came a sort of helpless splash. "Somebody will get drowned," he thought.
