THE SHADE TREE PROBLEM OF CITIES 
Extract from an Address before the Annual Convention of the American Civic 
Association, Baltimore, Md., by Henry N. Castle. 
Selecting and Planting the Trees 
The next question arises, what trees shall we plant? It 
would take a half hour to discuss the reason why the list of 
desirable trees for street planting can be counted on the 
fingers of one’s hands, and then not counting the thumbs! 
Experience has shown that the following are suitable trees: 
The Norway Maple, Oriental Plane, American Elm, Red, Thin 
and Yellow Oaks and the Japanese Ginkgo. With the proper 
care in handling from the nursery to the street root bed, you 
can count on these trees living and proving good street trees. 
Under specially favorable conditions you might add the 
European Linden, the Sweet Gum and the Paper Mulberry 
(the non-fruit-bearing variety). Where parkway areas are 
12 feet or more in width, or upon small parks, there may be 
grown, producing a beautiful effect, the Crepe Myrtle, pink 
and white alternating, the Horse Chestnut, the Smoke Tree, 
and, with a water margin, the Willow Tree. Each locality 
will have to work out and determine its . own proper trees, 
but, as will be seen, the list from which to choose is very 
limited. 
Having determined the kind of trees and the kind to be 
planted upon each street, then the question arises, what 
size tree shall we plant ? Here again experience teaches that 
with trees shipped from outside nurseries, those calipering 
1^2 to inch, 6 inches from the ground, are more likely 
to live than those of larger size. When trees can be taken 
from the home nursery and planted the same day they are 
taken from the ground, the larger sizes can be planted safely 
up to 2^2 to 3 inches caliper. In ordering your trees, secure 
bids from half a dozen or more reputable nurseries, specifying 
the number and size of each kind desired and condition that 
the trees shall be thrifty transplanted stock, free from 
disease, with straight trunks suitable for street trees, capable 
of trimming to not less than 7 feet from the ground, with 
uncut leaders and an abundance of fibrous roots, and that 
protection must be given the roots from the moment the tree 
is taken up until packed in the car with moist straw, leaves 
or mulch. On receipt of the car the trees should be carefully 
unloaded by your own men, the roots covered with damp 
burlap or other covering, so that there shall be no exposure 
to wind or sun from the car to your nursery, and there the 
trees should be heeled in immediately as unloaded from the 
wagon. When planting upon the streets take up only such 
trees as you may immediately need, keeping the roots covered 
with a moist covering until placed in their final location. 
The particulars as to the preparation of the root bed, manner 
of planting, the placing of guards, the after cultivation and 
watering of the trees, may be obtained from the specifica¬ 
tions adopted by the Norfolk Commission for the guidance 
of its men and inquiring citizens .—The American City. 
PANAMA-PACIFIC INTERNATIONAL EXPOSITION, 
1915 
San Francisco, Cal., January 6th, 1913. 
National Nurseryman Publishing Co., 
Rochester, N. Y. 
Dear Sirs: 
The Department of Horticulture of the Panama-Pacific 
International Exposition, realizing the necessity of calling 
the attention of prospective exhibitors to the preparations 
for getting such exhibits in order as they have in view for 
the exposition, is taking the matter up now so those who 
are interested will be fully in touch with the situation. 
In addition to the Horticultural building,- which will 
contain 207,000 square feet of floor space, there will be a 
large acreage available for exhibits of trees, flowers, shrubs, 
etc., in the open. The interest which is being manifested 
throughout the world in the exposition is going to make 
this space inadequate to fully care for all of the exhibits 
unless they are classified in such a manner that we will fully 
understand how to apportion space to the various divisions 
that will combine to produce an effective horticultural 
exhibit. 
On account of our very favorable climatic conditions, 
and the fact that the buildings to take care of the exhibits 
will be completed, we are planning to have the outside 
exhibits growing and in the ground at least a year in advance 
of the opening of the exposition. In order that exhibitors 
can prepare plants, trees and shrubs it will be necessary that 
they commence such exhibits as they may have in view not 
later than next spring. The horticultural display will be 
made one of the leading features of this exposition. The 
climatic conditions are so much more favorable than that 
of any other world’s fair held in the United States that we 
are placed in a position to bring about results from a horti¬ 
cultural standpoint which it has been utterly impossible to 
do heretofore. 
We would like to have you advise your State Commission 
what you will have in view for exhibition purposes, and 
impress upon them the importance of making sufficient 
appropriation at an early date to make an exhibit creditable 
to the horticultural importance of your State. If we can 
be of any assistance in bringing about immediate action in 
working up an interest in all matters pertaining to horti¬ 
culture we will cheerfully render any service in our power. 
Yours very truly, 
G. S. Dennison, 
Representative of the Chief, 
Department of Horticulture. 
National Nurseryman, 
Dear Sirs: Please continue my “ad” for another three months. 
Results have been very good.
