"In some parts of Mexico," writes James Hewett, "hot springs and cold springs are found side by side—and because of the convenience of this natural phenomenon the women often bring their laundry and boil their clothes in the hot springs and then rinse them in the cold ones."  On one occasion a tourist, watching nature's laundromat, commented that "Mother Nature is pretty generous to supply such ample, clean hot and cold water here side by side for their free use."  To his great surprise, however, the friend replied, "No señor, there is much grumbling because she supplies no soap."[1]
