It gets better. In her book Wendy Hodgson recounts a story from Spanish friars about the Seri Indians and Stenocereus gummosus, a cactus with fruit considered better than any other. In season they ate as many cactus fruits as possible, and hours to days later all the people left their waste in one spot on large rocks. The following year the cactus seeds were easily collected from the rock where they had been left. The seeds were ground to flour, cooked and eaten. The friars were told this after they ate the delicacy. Leo Martin Phoenix Arizona USA
