FROM THE PREFACE 
. “In telling tie story of this search for the mode by which the eaeth came 
‘into being, we have let the incidents that led the i inquiry on from one stage to 
nother fall in with the steps of the inquiry itself. It is in keeping with the 
purposes of this series of booklets that the motives which set researches going 
should have their place with the quests that arose from them. .... The final. 
ory of the birth of the earth will come only after a time, when the vestiges of 
tion have been more keenly discerned and more faithfully rendered than is © 
sible now.’
