34 PRACTICAL ARBPORICULT URE 
Far up in the Sierras, eighty centuries ago, she planted the giant Sequoias. 
There may have been other Sequoias growing elsewhere, and probably were, 
but they do not exist today. 
Near the summit of Pike’s Peak, and other high points in the Rockies, 
are groups of spruce above the line of other timber. 
In the Black Hills of South Dakota are forests of Pinus Ponderosa, the 
yellow or bull pine, which tree is not seen to the eastward. 
Along every stream from the Mississippi to the summit of the Rocky 
Mountains are found box elder and cottonwood. 
Throughout Indiana were dense woods of yellow poplar, black walnut, 
beech, catalpa and sugar trees. 
In Maine the white pine was placed in vast quantities, while in Massa- 
chusetts, although the pine and oak exist, yet a preponderance of the wood 
is of gray birch, scarlet maple, some of the inferior oaks, alder and in places 
chestnut. 
Notwithstanding the distribution of species of trees by nature, both in 
the old world and the new, man has asserted the dominion given by God over 
all herbs, and has transplanted the Sequoias into all portions of the world, 
and in many instances has succeeded in growing magnificent specimens. 
The Monterey cypress has been carried to every portion of California and it 
grows like weeds. 
The white pine is grown by millions in the world’s great nurseries. 
The chestnut has been transplanted and is now growing in thousands of 
localities where it was unknown under the unaided guidance of nature. 
Scientists have dwelt upon the peculiar soils and localities in which certain 
trees would thrive, drawing their inferences from the special locations in 
which nature placed them. But every nurseryman and tree grower has dem- 
onstrated the falsity of such theory by practically growing almost all kinds of 
trees in every conceivable location or character of soil. True, there are some 
instances where a combination of friendly environments are essential, but 
these are exceptions, not the rule of guidance. 
And now, while nature has neglected to direct the aborigines to bring to 
your state the oily nut which they planted from New York southward and 
westward to the edge of the plains, it is left for ‘The White Man's Burden” to 
perform this servce, and the duty should be cheerfully performed, and the 
walnut planted where it has not grown before. 
If the white pine must struggle for existence with a preponderance of 
worthless scrub oaks and birch, then destroy enough of the inferior wood to 
enable the superior to reach sunlight and gather strength for greater expansion. 
Thousands of acres of forest trees have heen planted upon the western 
prairies and plains, where no tree whatever had grown for centuries, vet the 
dwarf growths on these abandoned farm lands, serving as nurse trees for 
the protection of the pine and chestnut, and preparing a fertile soil in which 
worthier trees may flourish, give to New England an advantage which is en- 
tirely unknown on the prairies of the West. 
I fear the farmers of Massachusetts do not fully appreciate that wonder- 
ful collection of the world’s trees at Arnold's Arboretum. T would advise a
