wood of which is much used in Japan; Engelmann’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 southeastern Europe; 
and the tiger-tail spruce, from Japan, introduced about 
forty years ago, 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- 
tory, 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. Many 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 range 1. 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 white 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 white 
Swiss stone pine, of Europe and Asia; and the Macedonian 
white pine, of southeastern Europe. 
In the area to the eastward of range 1 will be found, 
among others, the Austrian pine, with a hard, strong wood 
which is much used; the variegated Scotch pine, with 
the young leaves variegated; and a number of plants of 
the white pine, Himalayan white pine and the Rocky 
Mountain, western, and Korean white pines. 
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 Japanese red pine, and several horticultural 
forms of it. Following these to the north are a number 
of plants of the Jack or gray pine, native of northern North
