One of his tricks nearly led to unpleasant consequences. Whilst out shooting one day, near Yarmouth, he killed an owl—a bird familiarly known in Yarmouth by the sobriquet of ‘Brother Billy.’ Having arrived at home, he went up into his mother’s room, with the bird concealed behind his coat, and, assuming a countenance full of fear and sorrow, exclaimed, ‘Mother, mother, I’ve shot my brother Billy!’ but the alarm and distress instantly depicted on the distracted countenance of his parent induced him as quickly as possible to pull the owl from under his coat. This at once exposed the truth and allayed the apprehensions of his mother’s mind, but the effects of the shock it caused did not so immediately pass away. Dr. Cooper determined to punish his son, and he therefore confined him, according to his usual mode of correction, in his own house. Astley was, however, but little disposed to remain passive in his imprisonment, and in the wantonness of his ever-active disposition amused himself by climbing up the chimney, and having at length reached the summit, endeavoured, by imitating the well-known tone of the chimney-sweeper, and calling out as lustily as he could, ‘Sweep, sweep!’ to attract the attention of the people below. Even on his father the incorrigible lad seems on more than one occasion to have tried his little game. One day, while the worthy Doctor was marrying a couple in the church, Master Astley concealed himself in a turret close by the altar, and, imitating his father’s voice, repeated in a subdued tone the words of the marriage-service as the ceremony proceeded, to the consternation of his father, who said that he had never observed an echo in that place before. Once or twice the lad’s life was in peril, as when his foot slipped on the top of the church, and he was unpleasantly suspended for some time between the rafters of the ceiling and the floor of the chancel. On another occasion he had a narrow escape from drowning. It seems that on the Yare are little boats out together very slightly, for the purpose of carrying a man, his gun, and dog over the shallows of Braydon, in pursuit of the flights of wild-fowl which at certain seasons haunt these shoals. When the boat is thus loaded, it only draws two or three inches of water, and is quite unfit for sea. Young Astley nearly lost his life in attempting to take one of these boats out to open sea. In this way young Astley Cooper, from his fearless and enterprising disposition, soon became a sort of leader of the Yarmouth boys, and at their head, for a time, seems to have devoted himself to every kind of amusement within his reach—riding, boating, fishing, and not unfrequently sports of a less harmless character, such as breaking lamps and windows, ringing the church bells at all hours, disturbing the people by frequent alterations of the church clock, so that if any mischief were committed it was sure, says his admiring biographer, to be set down to him.
