regarding the difficulty of shooting at station number 8 in that it "gives you about half as much time to shoot as the rest of them. You have to shoot much faster there."
 The high house from which the bird was released was built of 2 by 4 framing lumber, which was covered by corrugated metal. It was 9 1/2 feet high, 60 inches wide and 60 inches deep. The opening through which the bird was ejected, and behind which Tommy was employed in loading the trap machine, was in the east wall and was 7 inches long and 7 inches wide. The opening was shielded by two metal plates attached to the outer wall. The trap machine was mounted on a wooden shelf which extended 25 1/2inches back from the east wall of the high house. From the edge of this shelf to the rear or west wall of the house was 34 1/2 inches. Tommy testified that in operating the trap machine, he would place a bird in the machine and cock it by pulling down a throwing lever; then he would step back to the wall behind him so as to be clear of the upward swing of the throwing lever. After the operator in the control house released the bird, Tommy would step forward toward the machine and reload it. There was no communication between the high house and the control house, and Tommy would step forward to reload without knowing whether a gun was fired at the released bird. While
