Text Appearing Before Image:
g season the gutter becomes a gully.Here and there, in places, its banks undermine and fall in. Here and there therivulets from the field wear tiny tributary gullies. Between the breaks in thebanks and the tributaries irregular masses of earth remain standing, sometimesresembling mimic cliffs, sometimes washed and worn into mimic peaks and spires. Such roadside erosion is familiar to us all. A hundred times we have idlynoted the fantastic water-carved walls and minaretted slopes of these ditches.But seldom, perhaps, have we realized that the muddy roadside ditch andthe world-famous Grand Canyon of the Colorado are, from natures stand-point, identical; that they differ only in soil and size. The arid States of our great Southwest constitute an enormous plateauor table-land from four to eight thousand feet above sea level. Rivers gather into a few desert water systems. The largest of these is thatwhich, in its lower courses, has, in unnumbered ages, worn the mighty chasmof the Colorado.

Withii A Quiet Stretch between Two Rapids the Canyon the river is crossed by cars suspended on wire cables, and also, in quiet reaches,by boats; there are no bridges
