“I was able to place the end of one toe on the point of one picket, and thus balanced, wave the other leg in the air . . . When Walsingham pulled my hand I inclined gently toward him until I was at right angles to the picket fence, with my feet still on top of the picket; and when he released my hand, I slowly swung upright again.” – Amazing Stories Volume 1 Number 3.
