states, to say nothing of several superb forms which 
our Pacific coast friends have a monopoly of in their 
highest development.

the most rigid of spruces, and the dwarf growing P. 
Glehni are from the Japanese Islands northward. Of 
the Amorika spruces P. Ajanensis, with its often 
steeh' blue aspect, is also from Japan. P. Omorika 
itself is often slow and P. Sitchensis from the North- 
west Pacific coast, commonly tender, but Dr. Saunders, 
in a revision of the Ottawa list, kindly sent me re- 
cently, leaves it standing as hardy. P. obovata Sch- 
renkiana, and forms of P. orientalis, also seem to 
stand there, but the uncertain P. Morinda soon suc- 
cumbed. It does better on the Pacific coast. There 
are a superb lot of these spruces for the north, but 
any one will lose them at times in the height of their 
glory. Such casualties give opportunity for rear- 
rangement. 
Tsiiga, “hemlock spruces,” have six species in North 
America, the Himalayas and Japan. They have from 
three to six cotyledons. The leaves are small, flat- 
tish, linear and somewhat silvered on the under sides, 
while the roundish cones are terminal, pendulous and 
about an inch long or longer in the lighter green. T. 
Pattoniana. T. Canadensis has a considerable range 
from Nova Scotia westward to Wisconsin, and south- 
ward through New England and the hills of New 
Jersey to Delaware, thence along the mountains as far 
as Alabama. It is a beautiful tree at its best and 
grows up from 50 feet to sometimes twice that height, 
either in woods by itself or mixed with other kinds. 
It has a fondness for dry boulder covered hills, but is 
often found on richer soils along streams. The wood 
is poor, but largely used for common structural pur- 
poses. It bears the shears admirably and forms hand- 
some hedges. There are several varieties with larger 
or smaller leaves, dwarf and drooping habit, and with 
more or less glaucous foliage. T. Caroliniana is an 
allied species from the higher elevations of the South- 
ern Alleghenies. It has somewhat blunter leaves and 
larger cones, with spreading scales — not much to 
found a species upon — hut the new botanists dearly 
love that sort of thing. T. Brunoniana, the Hima- 
layan species, is found at elevations of from 6,500 to 
10,500 feet. It is a fine tree of 100 or more feet high, 
rarely or never seen in the States. T. Sieboldi is 
the Japanese kind, and grows with Pinus ])arviflora 
at the higher elevations. T. Pattoniana, or Hookeriana 
as some nurseries have it, extends from British Co- 
lumbia south-eastward to Northern IMontana and 
Idaho. It has a variety called argentea, and several 
forms are thickly branched and cpiite distinct. They 
are but rarely seen, however. The stateliest of the Pa- 
cific States forms is T. INIertensiana. It often grows 
from 100 to 200 feet high, both on rocky ridges and 
bottom lands, forming extensive forests along the 
western base of the Cascades. It ranges, however, 
from Alaska to N. California, eastward to the Moun- 
tains of Montana and Idaho. This species is the 
Prince Albert’s spruce of the English, and in their 
country it is held in some repute, having been grown

for fencing-. If it is sent east as “hemlock” it is good 
for nothing, but if sold as “spruce” it is capital good 
timber. In Perthshire, Scotland, there are trees from 
65 to 75 feet high. James MacPherson.
