SPRAYING C 
The following insects have been found 
doing considerable damage to the trees and 
shrubs in and about Chicago. I will en- 
deavor to enumerate them in the order' of 
their importance, or, perhaps better, de- 
structive ability: 
The Tussock Moth (Orgyia Leucos- 
tigma), a chewing insect, affecting the 
horse-chestnuts, lindens, willows, poplars, 
soft maples and birch. It shows its pref- 
erence in the order named. 
The boring insects have been multiply- 
ing with great rapidity in and about Chi- 
cago, or perhaps more truly speaking, we 
begin to recognize them more each year. 
There are many different varieties and they 
affect nearly every variety of tree. Per- 
haps the Poplar or Willow Borer ( Cryp - 
tnrynchus Lapathie ) is the most common 
and does most damage. The willows, pop- 
lars, soft maples, honey locusts, box eld- 
ers and cottonwoods are affected most, 
while the lindens, elms, ash, oaks and 
hockberry are affected in a lesser degree, 
and the ailanthus, catalpa, sycamore and 
ginkgo are not attacked seriously, if at all. 
The Scale insects are sucking pests and 
present in multitudinous numbers and 
many varieties. Most common is the Cot- 
tony Maple Scale (Pulvinaria Innumerabi- 
lis), which attacks the soft maples, box 
elders, lindens, willows and other trees in 
a lesser degree. 
The second most destructive Scale insect 
is the Elm Scale ( Chionaspis Americana ) 
and (Aspidiofus Ancylus ) ; both are seri- 
ous. I venture to say that it would be a 
difficult task to find even one American 
elm tree which has been growing in one 
of our parks or on our streets for five or

coction of the leaves is used iu the treatment of

Rhus copalina. Staghorn Sumach, R. typhina, and 
R. glabra. Bark and leaves rich in tannin, an in- 
fusion of the berries used as a gargle in cases of 
catarrhal sore throat. 
Ribes, Gooseberry and currant, species of. 
Fruit: diuretic. 
Rubusi odoratus, Flowering Rasberry, and species 
of this genus, which includes the blackberries and 
dewberries. Fruit: Diuretic, lexative, plant and 
flower: diuretic, leaves; astringent, purgative, bark 
of root: artringent used in dysentery. 
Spiraea opulifolia and S. tomentosa. Plant: as- 
tringent, diuretic, used in cholera infantum. 
Vaccinium, Cranberry and Blueberry, species of. 
Bark and leaves: astringent, root: diuretic, 
Fruit: astringent, anticorbutic, diuretic. Xantho- 
xylum Americanum, Prickly Ash, Toothache Tree. 
The bark is an active stimulant and is used in de- 
coction to produce diaphoresis in cases of Theu- 
matisrn and syphilis, and as a popular remedy 
for toothache.

The following letter to President Wilson 
and his reply will be of interest to mem- 
bers : 
November 19, 1913. 
Hon. Woodrow Wilson, 
President of the United States, 
White House, Washington. D. C. 
Sir: The undersigned, constituting the Execu- 
tive Board of the American Association of Park 
215 
Superintendents, has voted to oppose the principle 
of granting in any national park or monument 
either temporary or permanent rights in favor of 
individuals, corporations or states that shall im- 
pair the beauty, freedom of use, or safety of such 
holdings. On this ground we oppose the proposed 
grant to San Francisco, Cal., of reservoir and 
power privileges in the Iletch-Hetchy Valley of 
the Yosemite National Park, that a bill pending in 
the United States Senate provides for, and also 
because it has been shown that such a grant is 
unnecessary. 
Respectfully, 
H. S. Richards, President; G. W. Burke, Vice- 
President; F. C. Green, Vice-President; Frank 
Brubeck, Vice-President; W. S. Manning, Vice- 
President; G. Hennenhoffer, Vice-President; G. 
Champion, Vice-President; J. J. Levison, Secy.- 
Treasurer. 
Department of the Interior, 
Washington. D. C., December 15, 1913. 
Mr. J. J. Levison, Secretary- Treasurer, 
The American Association of Park Superintend- 
ents, Brooklyn, N. Y. 
Sir: I am in receipt, by reference from the 
President, of your letter protesting against the 
use of the Hetch-FIetchy Valley in connection with 
the development of a water supply, etc., for the 
city of San Francisco, Cal. 
This matter! has been placed on file and will be 
given consideration. 
Respectfully, 
ADOLPH C. MILLER, 
Assistant to the Secretary.

rapidly they multiply and migrate, it is

the health and growth of our best shade 
tree, the American elm. 
The Walnut Scale, the Scurvy Scale, 
the Oyster Shell Bark Scale and San Jose 
Scale are other varieties of these de- 
structive pests. 
Then we have several varieties of the 
Aphidae, as the black, red and woolly 
Aphis, which are sucking insects, as well 
as mealy-bugs. All do considerable dam- 
age to our trees and shrubs, but I think 
there is hardly any excuse for the con- 
tinued existence of this class of pests, 
because they are so easily destroyed by 
the use of a weak solution of kerosene 
emulsion. 
The tent caterpillar has been found af- 
are the various gall-making insects. Those 
common are the so-called Cocks Comb Gall 
( Coloplia nUnicola Fitch). The ( Phytop - 
tus Quadripes), a four-legged mite, can 
be destroyed by applying a weak solution 
of kerosene emulsion in the spring, and 
are also destroyed by gathering the galls. 
Another class of insects are the grubs 
working under ground and affecting the 
minute root hairs, as the June bug, de- 
stroyed by turning the sod and picking out 
the grubs or larvae. In combating these 
pests they may be placed in three groups, 
the chewing, sucking and boring' insects. 
The chewing insects, as the Tussock 
Moth, Tent Caterpillar, etc., can best be 
exterminated by spraying the trees just
