for which I plead, earnestly calling upon my fellows to so adjust their own lives that they will strike the happy mean, thus _living_ (not merely talking about) the dignity of labor as well as the joy of mental and spiritual occupation. Another important thing must not be overlooked. As a result of this out-of-door life the Indian is an early riser and an early retirer to bed. The civilized habit of turning night into day, living in the glare of gas and electric light, is, on the face of it, artificial, unnatural, and unhealthful. It is indefensible from every standpoint. There is not one word of good can be said of it. The day is made for work, the night for rest and sleep. The use of artificial light to the extent we indulge it in civilization is gradually rendering normal eyesight a rarity. Children are born with myoptic and other eye-diseased tendencies. Sometimes it seems as if more people, of all ages, wear glasses than use their natural eyesight, and this is but one of many sad consequences accruing in part from our reversal of the natural use of the day and night times. [Illustration: HAPPY AND HEALTHY HOPI CHILDREN, ASKING THE AUTHOR FOR CANDY.] Many men, literary and others, wait until the quiet of evening to do their work. They often stimulate themselves with coffee, and even stronger beverages, and then work until the “wee sma’ hours,” by artificial light, _after they have already done a fair day’s work_. We used to hear a great many words of commendation of the youths in school and college who “burned the midnight oil.” If I had my way I would “use the leather strap” upon all these burners-up of their physical and mental forces at the time God intended they should be abed and asleep. The time for mental work is in the early morning after a hearty, healthy, good night’s sleep. The body is strengthened, the mind refreshed, and thought flows easily and readily, because all weariness has disappeared under the influence of “tired nature’s sweet restorer.” Mental work done at such time is not only a pleasure, but is well done, properly done, because the conditions are right for its doing. Nor is this all. There is a mental and spiritual pleasure given to the early riser that the late sleeper knows nothing of. One of the most beautiful baskets in my historic collection of Indian baskets is one made by a Coahuila woman who depicted thereon the white light of the morning shining through the dark silhouettes of the sharp points of the giant cactus. Her æsthetic enjoyment was thus made the inspiration of a real work of art.
