This problem is rather unique in its principle of operation and offers
at once material for study and investigation. Like that of a circus
performer, the combinations must be exactly right or the little fellow
may fall on his head. In making the man, first bore the holes thru
the block and take care to make them parallel. The openings into the
holes from the ends must be in the same plane and made to slide over
the rounds of the ladder without friction. The tumbler may be shaped
and colored to look like a man. A base may be attached to each end,
but on opposite sides of the ladder, so that Tommie may tumble in both
directions.
