George Wharton James,
What the White Race May Learn from the Indian
“ THE INDIAN AND SOME LUXURIES Most city men regard a shampoo as a city luxury of modern times, except, of course, for the rich, who could always have what they desire. Yet the shampoo is more common with some Indians than with us, and they enjoy it oftener than we do. The Indian’s wife takes the root of the amole, macerates it, and then beats it up and down in a bowl of water until a most delicious and soft lather results, and then her liege lord stoops over the bowl and she shampoos his long hair and scalp with vigor, neatness, skill, and dispatch. ”
