Abstract
EARLTER CHAPTERS OF THE HISTORY OF THE PLANT WORLD. IT may be helpful as a preliminary to my treatment of certain aspects of plant-life in former ages to glance at a table of contents of the geological history of the world. The crystalline rocks classed by geologists as Archaan represent inconceivably ancient land surfaces on which were accumulated vast piles of detrital material furnished by agents of erosion, and from time to time products of volcanic activity. Plants may have lived on the Archan, or pre-Cambrian, continents; they probably did, but as yet we have no certain knowledge of them.
