 its presence in epochs coeval with those in America

 conditions throughout an inconceivable period of 

 time, as proved by the geological record, it seems 

 passing strange that it should so comparatively 

 recently have disappeared. What caused its disap-

 to the present. 



The earliest known mention of the Ginkgo in books 

 is in a Chinese work on agriculture which dates from
