Carrying Power of the River. This suggests another singularity in which it doubtless reigns supreme. Probably no river in the world, of its length, has anything like the carrying power of the Colorado within its waters. Notice that I say "within its waters." It is useless for carrying anything on its bosom. No ships use its waters for beneficent commerce. Its only carrying power is in the amount of sand and other material it holds in solution, and carries within itself.

Its Incredible Descent. For it is doubtful whether any river in the world has so rapid a descent from towering mountain heights to its receiving ocean, as has the Colorado. It falls over four thousand two hundred feet from its source to its mouth, and in less than five hundred miles of its distance it contains five hundred and twenty rapids, falls and cataracts. A fall or a rapid or a cataract for every mile, and a few over for good measure. Who can conceive the peril of journeying through such a river? And until the facts were known, how hopeless to attempt to ascend such a river, as did Alarcon, Ives and Wheeler!
