Surely corn is the "mother" of the Hopi. All the powers of nature are invoked to grant a good crop by giving rain and fertility, and the desire for corn is the central motive of the numerous ceremonies of the villagers of Tusayan. If the prayers of the Hopi could be formulated like the "_Om mane padme hum_" of the Hindus, it would be in the smaller compass of these words, "Grant us corn!" Nor are these simple villagers ungrateful for such blessings. Kopeli used to stand looking over his thriving cornfield and say with fervor, "_Kwa kwi, Kwa kwi_," "thanks, thanks," and it was evident that the utterance was made with true thankfulness and a spirit of devotion. It is difficult to imagine the ancient people without corn; but very long ago, as the legends tell, they did not know this cereal. Certain it is they were not then pueblo dwellers and had not spread far in the Southwest. They lived in the places where there was game, and for the same reason that the important food animals lived in such places,--the presence of vegetation that would sustain life. Their life was along the foot hills of well-watered and timbered mountains rising from plains, where with the flesh of game and seeds and roots of plants they could supply their semi-savage wants. Long perhaps they roved thus as hunters until they drifted to the land of promise--the semi-desert where agriculture of grain plants was born and there they received "mother corn." Henceforward all the former sources of food wrested from a niggard Nature became as nothing to this food of foods, but even to this day the Hopi have not forgotten their old-time intimate knowledge of the resources in fields not sown by human hands. With corn, which possesses a high food value and is easily raised, stored, and preserved, the Hopi and their Pueblo brethren spread without fear throughout the semi-arid lands. It has been pointed out that a constant diet of corn produces disagreeable physiological effects, and this is suggested for the use of chile and other condiments, the mixture of corn food with meat and vegetable substances, and, in fact, for the multifarious ways of preparing and cooking corn. This necessity for variety also gives an explanation of the resourcefulness of the Hopi housewife and has acted as a spur to her invention of palatable dishes.
