Coming of Man. But now the new life is coming! With verdure and animal life in existence, these hitherto uninhabitable regions became capable of sustaining human life. And the restless spirit of the human race, wherever and howsoever it originated, drove bands of men and women into this region.

Who were they? What were they like? Whence did they come? How long did they stay? Whither did they go? are questions one naturally asks in regard to these first discoverers and inhabitants. If I were to say "I do not know," I would be saying what every other thinking man is compelled to say. Yet there is pleasure in conjecture.

Traces of Ruins. Before looking at these conjectures, however, it is appropriate that we look first at what facts there are to justify them. Suppositions without any facts are mere fictions of the imagination, and this we are not indulging in. When in our day men began to explore the Grand Canyon and its numberless tributaries, a great number of indications of man's presence were found on the rim, on the fault lines or breaks in the sheer precipitous walls, on the plateaus and in the Canyon beneath, in the shape of crude house ruins, lookout houses or forts, indifferent trails, cliff-dwellings, hewn-out water cisterns, mescal pits, with countless pieces of broken pottery, arrowheads, stone axes, hammers, mortars, pestles and even cemeteries. or places of cremation.
