And when I was supposed to be well again,--months afterward,--I found that the deadly poison had in some way lodged in the lining of the stomach, so that, at times, it would cause a nervous and muscular disturbance that made me suffer intense agony. I then recalled the use of mud by my Indian friends, and I hied me away as speedily as I could to the hot mud baths of Paso Robles, in California. There the sulphur water at a temperature of over 110° Fahrenheit comes bubbling into a great wooden tank filled with the soft, velvety mud, black as ink, of the tule marsh. Into this tank I stepped, and gradually worked my way into the mud, lying down in it, and wriggling and working my body until I was as near covered as I could be. I brought great armfuls of the hot, soft, and soothing nature poultice over my stomach and body, and then lay there as long as it was wise to do so. What mattered it that I was blacker than a negro when I came out. Two minutes with a bucket and a hose and I was cleaner than ever. One week of these baths and I lost the poison, never again to return. I never think of Paso Robles and the mud baths there without a deep sense of gratitude that some of us at least have learned how to utilize some good things that the Indian has taught us. CHAPTER XV THE INDIAN AND THE SEX QUESTION Having studied medicine somewhat in my life, I have been permitted as a “medicine man” to know more of the intimate life of the Indian women than many white men. In this article I propose to give the results of many observations in this field, with full assurance that there are many things the white woman may learn from the Indian, both in her treatment of herself and her children. In the first place, the period of adolescence in both boys and girls is regarded with the importance it deserves.
