branching until some distance above it. This collection is 

 only partially formed, but additions are made to it every 

 season. The groups will be referred to in the order of their 

 sequence. 



The first is the willow family which occupies the low-lying 

 land near the southeast entrance and the ridge to the north, 

 where a collection of willows and poplars may be found. 

 Of these Simon's poplar, from China, is of rapid growth and 

 upright habit, and more graceful than the cottonwood or 

 Carolina poplar; the American aspen, a native of northern 

 North America, the wood of which is largely manufactured 

 into pulp for the making of paper; in northern British 

 America it is the principal fuel of the Indians, as it burns 

 freely when green and without sparks ; the inner bark, which 

 is sweet, is often used by them as a food in early spring. 

 This tree has been of great service in re-foresting large tracts 

 which have been denuded by fire ; the long hairy appendages 

 to the seeds enable the wind to carry them far and wide, and 

 as they germinate quickly and the young seedlings grow 

 rapidly in exposed situations, it is admirably adapted to the 

 above purpose, quickly furnishing a covering for the land 

 until more desirable trees may get a foothold. Bolle's pop- 

 lar, a form of the white, or silver-leaf poplar, is quite orna- 

 mental in its lobed leaves; the white or silver-leaf poplar is 

 a native of Europe and Asia. Another ornamental tree and 

 one frequently used where quick growth is desired, is the 

 eastern cottonwood, or Carolina poplar, common in eastern 

 North America. There also is the Lombardy, or Italian 

 poplar, from Europe and Asia, with its tall spire-like growth. 

 Among the willows are the golden willow, from eastern 

 North America, and the weeping willow, native of Asia, a 

 tree commonly planted for ornamental purposes, and some- 

 times known as Napoleon's willow. 



The walnuts and their relatives may be found to the west 

 of the nursery on the ridge. The narrow-winged wing-nut, 

 from China, and the Rhoeas-leaved wing-nut from Japan, 

 are both here. Of the walnuts (Juglans), the English wal-
