HARRISON’S NURSERIES, BERLIN, MD. 
a tapering trunk. Develops cone-shaped, the most even and 
regular of all evergreens. A solid, substantial, sturdy, reliable 
evergreen which should be planted at every home in the 
country. This variety is grafted. That is, we cut scions from 
the bluest and handsomest specimens we can find, and graft 
them on sturdy seedling roots. This insures that every speci¬ 
men will be of the true blue color. Seedling Blue Spruces 
often revert to the green type after a few years, or in other 
cases are green when young and become blue when older. 
Colorado Blue Spruce. The same thing as Roster’s Blue 
Spruce except not grafted. Our Colorado Blue Spruce trees 
have been watched carefully. They are propagated from 
seed harvested from true blue trees and all seedlings showing 
any tendency to revert to green are not offered as blues. 
Norway Spruce. One of the most largely planted ever¬ 
greens all over the country. Is extremely rapid-growing, 
graceful and handsome, gets very tall, is at home any place 
you plant it. Norway is suitable for specimen planting, but 
it is not so good set singly as Blue Spruce, or Firs, Pines, etc. 
The place for Norway Spruce is in windbreaks, shelter- 
groups and forest-plantings. 
White Spruce. Greatly resembles Blue Spruce in every¬ 
thing except color of foliage. The needles are light green, 
and have an agreeable odor. A fast grower. Does not get 
quite so large as Norway. Extremely hardy and one of the 
best evergreens for windbreaks, shelter-groups and planting 
of any kind in exposed positions in the North. The cones 
are slim, less than 2 inches long and glossy brown. If you 
want to make a permanent screen or windbreak about your 
home, plant this Spruce. 
HEMLOCKS 
When planted alone, where there is plenty of light, air, and 
root-space, Hemlock trees grow to enormous size, with a 
tapering trunk several feet in diameter at the base. The 
branches are slender and short, and the twigs usually droop 
a little toward the end. The foliage is fine and lacy, two 
rows of the half-inch needles growing out at either side of 
twigs and small branches.. Cones, of which there are large 
numbers, are only half an inch long and look like nuts. 
Hemlocks make wonderfully fine hedges; in fact, no other 
hedges can compare with them in beauty. In about ten years 
they get to be 8 feet high and 6 feet broad, when properly 
clipped, and then they are good for one hundred years. 
Hemlocks thrive in various soils, wet and dry, high and low. 
They grow out in the full sun,.or in heavy shade. The trees 
do well when planted among pines and spruces, or deciduous 
trees, in groups or windbreaks; to tell all the uses of Hemlocks 
would be to go over the list of the uses of evergreens. Get 
perfect trees to start with and you will not be disappointed 
with the beauty of your Hemlocks. 
Canadian Hemlock. Sometimes called Hemlock Spruce, 
and known botanically as Tsuga Canadensis. The fine, flat ' 
foliage is shining dark green, and small branches droop from 
the heavy trunk. The cones are a half-inch long. Grows 
very large when given plenty of space, but thrives just as 
well when planted thickly in a hedge, either when trimmed 
or left to grow naturally. 
PINES 
The old reliable evergreens, some of which should be in¬ 
cluded in every ornamental planting. No trees grow faster
