 lived to produce them ; unless transplanted at 

 an age, in which it was otherwise unadvisable 

 to move them ; by which many were also lost. 



But to those who delight in following nature 

 through all her various ways, and assisting her 

 by the timely exertions of genius, every ob- 

 stacle is but a fresh stimulus to their industry 

 to collect the smallest occurrences, which tend 

 to improve their former ideas on the subject 

 contemplated ; thus by a series of observations 

 it was found, that the old wood of these, as well
