"Hum! Suthin's wrong," murmured the inventor. "Guess it got a leetle stiff comin' over in th' wagon. I'll jest give it a start. Where's a pole? Mandy, git me a clothes pole."
His wife went to the back yard, where she had noticed some, and while she was gone the boys looked at the apparatus.
It consisted of a big wheel, with spokes made in zig-zag fashion. The spokes were shaped like a trough and contained a number of metal balls, which were prevented from falling out, as the wheel turned, by some strips of wood.
