foliage is extremely soft; the needles are long, with a 
pleasant bluish cast — creating the impression of a very 
superior White Pine. Certain forms of the tree are hardy 
The one known as Griffith's Himalayan Pine (JPinus Griffi- 
th ii) appears to be the best of those which have found 
their way to this country. It is not a tree which will 
be happy in a restricted area nor will it do well on poor 
sites, but in a proper location it has no rival. 
PONDER OS A PINE 
The Bull Pine or Ponderosa Pine (Pinus Ponderosa) is 
an important timber tree in the West. Obviously, it must 
eventually become a big tree. On good soils in the Mid- 
dle West select trees grow to immense size. The needles 
contrast strongly with those of the White Pine, being 
longer, stiffer, and a darker green. It produces a much 
denser shade than White Pine and requires a great deal of 
room for its maximum development. In youth, it grows 
rapidly and is tolerant of ' our hot summers. 
BUCK PINE 
Here is an old introduction which will grow rapidly 
for thirty years; slow down suddenly, and exhibit all 
the characteristics of an aged Pine. The Austrian Black 
Pine (Pinus nigra) is one of the few Conifers which can 
exist in the polluted atmosphere of the cities. If given 
ample room and allowed to develop as a specimen, it will 
exceed forty feet in height with a spread almost as great, 
and retain its lowermost branches. The foliage is very 
stiff, dark in color, and the needles sharp pointed. The 
winter candles are white and quite interesting. It is 
perfectly at home in the Middle West and can be used as a 
specimen, a group, or part of a border planting. 
SCOTS 
Perhaps no other tree has been so widely planted as 
the Scots Pine {Pinus syluestris). The failure of the 
tree has had an unfortunate influence on the use of Urg 
Conifers in this area. The Scots Pine varies tremendous 
ly over its range across Europe, and seeds from some re- 
gions produce very inferior trees. The situation became 
so alarming that European foresters drafted the ^^^s^ 
Seed Certification Law in the nineteenth century, ini^ 
''as designed to prevent the planting of more inferior
