“ On this part of our journey, Indian girls, with chicha and chupe for sale, are seated at the tops of the steep ascents. Chicha is the favorite drink of the Indians. A party—generally old women—seat themselves around a wooden trough containing maize. Each one takes a mouthful, and mashes the grain between her teeth—if she has any—and casts it back into the trough in the most sickening manner. As the mill-stones are often pretty well worn, the operation requires time and perseverance. ”
