14 Isaac Hicks & Son, Westbury Station, N. Y.— Deciduous Trees 
American Chestnut, continued 
ting is practical on isolated trees, but in 
the forest is very expensive. 
Dr. Haven Metcalf, Division of Forest 
Pathology, United States Department of 
Agriculture, is experimenting along these 
lines in the young orchard of Mr. R. Dudley 
Winthrop, Westbury Station, L. I. In this 
orchard and that of Mr. Charles R. Steele, 
and in our Nursery, he finds the Japanese 
Chestnut immune. 
The disease is new to science. Dr. Mur- 
rill, of The New York Botanical Garden, 
Bronx Park, named it in 1906, Diaporthe 
parasitica. One hope is that, like many 
other plagues, it will go in waves and, later, 
largely disappear. 
It may be a blessing in disguise. On 
many Long Island private estates the 
woodlands will be more beautiful if gradu- 
ally thinned out, according to the principles 
of landscape forestry described on page 4. 
Ninety-nine per cent of owners have not 
the knowledge, imagination and courage 
to do it. Now the diseased trees have to 
be cut, and the Oak, Hickory, Tulip and 
Dogwood will have a chance to develop 
into broad, handsome trees. 
Cut the trees before they rot. Take them 
to a saw-mill, or get a portable saw-mill to 
cut them into framing timber or other lum- 
ber. Show that Long Island is not entirely 
dependent on imported lumber. There is 
also a market as telephone poles or cord 
wood. Felling trees and dragging out logs 
does some damage to other trees, but it soon 
disappears. 
These big, old Catalpas are offered at low prices. 
They are strong, healthy, broad and shady. With 
Silver Maples, they will give the most foliage for the 
expenditure of any tree we offer. 
Chestnut • Castanea 
• American. Castanea Americana. This is an 
important timber tree of Long Island; in its 
maturity a majestic tree remarkable for the 
breadth and depth of its shade. 
A serious fungous disease is killing the 
Chestnut trees in the forests of Long Island. 
It frequently kills 20 feet of the top or may 
work lower down on the trunk. It starts 
from a spore in a crotch or wound which 
sends out mycelium or threads of the fungus 
penetrating the bark next the wood. In a 
few months it girdles the branches and the 
leaves turn yellow and drop. A tree appar- 
ently healthy in June may be half-dead in 
August. The fungus produces spores in 
orange pustules or jelly horns on the dead 
bark. There is no treatment known, except 
to cut off affected branches and cut out 
dead bark on the trunk, and larger branches 
before they are girdled. Cut an inch or 
more beyond the edge. 
In similar work on pear blight in Cali- 
fornia, it is advised to disinfect tools and 
wound with corrosive sublimate, one to 
one thousand. This remedy, painting the 
cuts with tar, and spraying with fungicides, 
have not been thoroughly tested. The cut- 
The White Dogwood 'is one of the best for planting by the hundred. 
The broad palms of foliage make a picturesque outline with deep 
shadows.
