As regards the kind of tree to plant, it is obvious that the 
selection of native species is more in harmony with the Arbor 
Day idea. But it is an unfortunate fact that scarcely any native 
species thrive under the difficult environmental influences of a 
crowded city. However, this is less applicable to the conditions 
in the suburbs and the school grounds. The following list em- 
phasizes native species wherever possible:* 
For New York and Vicinity 
City Streets 
1. Pin Oak. 3. Norway Maple. 
2. Oriental Sycamore. 4. Gingko. 
Suburban Streets 
5. American Elm. 7. Sugar Maple. 
6. Red Oak. 8. Red Maple. 
Also Nos. 1-4. 
School Grounds 
12. Beech. 15. White Pine. 
13. Flowering Dogwood. 16. Blue Spruce. 
14. Red Pine. 17. Magnolia sp. 
Also Nos. 1-8. 
This year is the 50th anniversary of Arbor Day. Since its 
inauguration we have passed safely through many crises, of which 
the last threatened to jeopardize the cause of liberty throughout 
the world. Let us all therefore make every effort to celebrate the 
occasion with proper spirit and a sincere thankfulness to the 
providence of God. Too many demoralizing influences are at 
work these days among our young people, and young minds are 
far more plastic than in later years. Nothing is more wholesome 
than a love of nature, and a child who has an interest in trees and 
flowers can never go far wrong. We can each year contribute to 
good citizenship and a clean moral tone throughout the country 
by a serious, thoughtful, and appropriate observance of Arbor Day.
