in order A D ill C iv to tell which boy strikes the hardest blow and fig 6 5 shows how to make a simple device tor for recording the relative heights at a distance of about 20 feet from the strength tester drive a 5 foot stick into the ground and about 9 inches in back of that stick and in line with it and the strength tester drive a 3 foot stick into the ground this shorter stick should have a third stick pivoted to one side near tho the top as shown in fig 6 now then to use the measuring device eight along the edge of the pivoted stick na as shown by the little dla dia gram of an eye in ili fig 6 and as the ballis ballia thrown into alia ir from the beam of the strength tester swing the stick so ab that its end follows the ball 3 D 4 when tha hall ball reaches tite the highest point
