of the foliage 

 of the Euro- 

 pean aspen 

 has been re- 

 marked by 

 writers from 

 the earliest 

 times. Ger- 

 arde, in 1597, 

 remarks that 

 the tree ' 'may 

 also be called 

 Tremble, after 

 the French 

 name, consid- 

 ering it is the 



matter whereof womens tongues were made, (as the Poets and 

 some others report) which seldome cease wagging. ' ' 



A characteristic interest attaching to this tree is the profusion 

 of very long catkins which appear in earliest spring, even before 

 our native poplars 

 are in bloom. They 

 appear at Ithaca 

 late in March or the 

 first of April. The 

 staminate or male 

 catkins are particu- 

 larly pleasing, and 

 planters should se- 

 lect that sex, if pos- 

 sible. The illustra- 

 tion on the next page 

 shows these inter- 

 esting iiower-clus- 

 ters nearly full size.
