01 geography in past epochs are to be read from the traces of events in minerals such as are illustrated by the formation of liquid inclusions in crystals the optical deformation that shows whether feldspar has been red hot and the wearing of pebbles through the character of the sand the dunes of El holland olland were traced to the scandinavian rocks the shapes of sand grains are found to bear certain relations to the distance they have been transported ed and the velocity of the current that thai carried them and it is suggested that some day we may read such lessons so thoroughly as to be
