how they got that way 



ONCE, A VERY LONG TIME AGO, DINOSAURS LUMBERED OVER 



parts of what is now Arizona and, departing, left behind 

 them footprints in the muds of time. Occasionally the mud 

 hardened into stone and the prints are pointed out to 

 visitors. Concerning them a pleasant story is told. 



"Them footprints," said a guide, "is four hundred million 

 and four years old." "But how can you be so precise as all 

 that?" "Well, (apologetically) of course I don't really 

 know nothing about it myself. But when I came they 

 told me they was four hundred million years old. And 

 I been here four years."
