One fine summer afternoon they were out on the water with two or three other boys of their own age, when a barge was seen ahead at some short distance from the shore. She was apparently floating down with the stream, and the fact that a horse was proceeding along the towing-path a little way ahead was not noticed, as the rope was slack and was trailing under water. The boys, therefore, as they were rowing against stream, steered their boat to pass inside of her. Just as they came abreast of the horse a man on the barge suddenly shouted to the rider of the horse to go on. He did so, the rope tightened, rose from the water just under the bow of the boat, and in another minute the boys were struggling in the water. All were good swimmers, and would have cared little for the ducking had it occurred accidentally, but the roars of laughter of the bargeman, and the chaff with which he assailed them as they scrambled up the bank, showed clearly enough that they had been upset maliciously. The boys were furious, and one or two proposed that they should report the case, but Tom Scudamore pointed out that the bargeman would of course declare that it was a pure accident, and that the boys were themselves in fault in not looking out whether the barge was being towed, before going inside her, and so nothing would come of reporting.
