ii.] OF THE ANCIENTS. 57 



He also says, that from the buds of the Poplar 

 exudes a resinous juice having a fragrant smell. 

 This exists in the buds of the White and Black Pop- 

 lar, but is more remarkable in those of the P. bal- 

 samifera and candicans, from America, which afford 

 a perfume collected from the trees in the spring, 

 and formerly imported from Canada into England. 



As to the Lybian, it is generally set down as 

 P. alba, though perhaps without sufficient reason. 

 We are, however, assured that of the genus Populus 

 there exist in Greece three species, of which one 

 seems really indigenous, namely, P. alba, with its 

 variety, Populus grceca, of Aiton, found in dry situ- 

 ations. Next to this P. nigra is the most frequent, 

 P. tremula being the rarest of the three. The 

 former is found throughout the country in moist 

 places about brooks and springs, also in swampy 

 spots near the sea, as at Phalerus, and sometimes 

 even where there is but little water. Fraas saw it at 

 a height of 2,000 feet above the level of the sea. 

 Of all the trees which once embellished the soil of 

 Greece, it is the one which has best resisted the 

 destroying agencies that have been at work in some 

 parts of this country indeed the only lofty one that 

 remains. These Poplars always stand in groups, 

 and form agreeable groves, formerly dedicated to 

 Hercules. They now, however, are found only in 

 a few localities. 



Populus nigra grows further from dwelling-places, 

 and more rarely near rivers and ponds, although 

 Fraas did not observe it on any remarkable heights.
