"Suppose you should wake up Christmas morning and find yourself to be the owner of a bicycle. It is a brandnew wheel and ever ything is in perfect working order. The bearings are well oiled the nickel is bright and shiny and it is all tuned up and ready for use. If you are a careful sensible boy you can have fun with it for a long time until finally like the "One Hoss Shay" in the poem it wears out and goes to pieces all at once. On the other hand if you are careless or indifferent or lazy you may allow the machine to get out of order or to become rusty from disuse or perhaps when a nut works loose you neglect it and have a breakdown on the road or you may forget to oil the bearings and in a short time they begin to squeak and wear. If you are another kind of a boy you may be careful enough about oiling and cleaning the wheel but you may also be reckless and head strong and will jump over curbstones and gutters or ride it over rough roads at a dangerous rate of speed and in this way shorten its life by abuse just as the careless boy may by neglect."
