Other spruces of interest here are the Yesso spruce, the 
wood of which is much used in Japan; the white, or Engel- 
mann’s, spruce, from western North America, the wood of 
which is largely manufactured into lumber and the bark 
sometimes used in tanning; the Servian spruce, one of the 
largest and most valuable timber trees of Europe; and the 
tiger’s-tail spruce, from Japan, introduced about forty 
years ago, and one of the hardiest Asiatic species in cul- 
tivation. 
The space allotted to the pines (Pinus) embraces the 
region to the eastward of the spruces and public conserva- 
tories, range I, extending across the road to the herbaceous 
grounds. Most of the pines are of great economic impor- 
tance, furnishing large quantities of lumber, turpentine 
and resin. Most of the white pines will be found on the 
westerly ridge of the herbaceous grounds and across the 
road from this to the eastward of the conservatories. 
Among these is our common white pine, which is perhaps 
the most valuable of the timber trees of northeastern 
North America, large quantities of lumber being derived 
from it. Near this is the Himalayan pine, resembling it, 
but with longer drooping leaves and the cones borne on 
long stalks; this sometimes attains a height of 150 feet 
in its native country, where its lumber is much used for 
building and other purposes. In this region will also be 
found the Cembra or Swiss stone pine, of southern Europe 
and northern Asia; and the Macedonian pine, of south- 
eastern Europe. 
In the area to the eastward of the conservatories will be 
found, among others, the Corsican pine, with a hard, strong 
wood ene is much used; the variegated Scotch pine, with 
the young leaves variegated; and a number of plants of both 
the white pine, Himalayan pine and Corsican pine. 
In the region to the north of the white pine tract, and on 
the westerly side of the herbaceous grounds ridge, will be 
found the Tyrolese mountain pine, from the Tyrolese and 
Venetian Alps, forming a group of some dozen plants; near
