34 PRACTICAL ARBORICULTURE 



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 dirty 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 expansii m. 



Thousands of acres of forest trees have been planted upon the western 

 prairies and plains, where no tree whatever had grown for centuries, yet 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. I would advise a
