What material has been left by the wayside for the history, not to be altogether despised because of its rusticity, of the unstable ways of one of the ancient peoples of the world, now few in numbers, forgetful of the past, estranged from the customs of their fathers, and dying without mourners and without records? Search the sites of camps the track passes, and there is naught to tell of the manner of those who recently occupied them save a tomahawk or a rare domestic implement of stone, and such stones do not preach thrilling but distinctive sermons. Why hurry along this pleasant way? Is not the one domestic appliance of the long-deserted camps worthy of passing notice? There it rests, half buried in the sand--a worn stone, with two others complementary to it to be had for the searching. It is meet that the most primitive of mills should be examined, and that one of the several and slow processes by which a poisonous, repugnant, and intractable nut was wont to be converted into food should be cited to the credit of the economic forethought of the most thriftless of people. On adjacent flats and slopes grow survivals from one of the most ancient of all plants--a Cycad, that botanical paradox, combining some of the characteristics of the lie palm and of the pine with the appearance of a tree-fern, while being of distinctive order, which flourished during the age when the Iguanodon and the Polacanthus and other monstrous and ungainly reptiles roamed the land. Let us rest awhile reviewing the earlier operations by which its nuts were rendered innocuous, and while the ghosts of the past make and bake their bread.
