A HARD MACHINE TO RIDE.
"Papa, what is a bicycle, anyhow?" asked Jack.
"Why, it's a two-wheeled vehicle, the wheels being placed tandem. The word is derived from bi, meaning two, and cyclus, a wheel. If it had one wheel it would be a unicycle."
"I've ridden a unicycle many a time."
"You? Where?"
"In the garden—in the wheelbarrow."
