The largest and most highly 
colored apples grow at the top 
of the tree where they get most 
sunshine. Yet the average spra¬ 
yer will not reach them. 
That’s the reason that most of 
the prizes at fruit shows are won 
by users of Hardie sprayers. 
These machines with their 
large capacities, high pressure 
and the famous Hardie Orch¬ 
ard Gun enables owners to 
put a fog-like spray into the top 
of the tallest trees. The Hardie 
gun will shoot a narrow, high 
stream and break just where 
you want it; or it is instantly 
changeable into any width fan 
spray—and stays set without 
holding 
control 
handle.

Hardie Sprayers — power and 
hand —are made in many sizes to 
6uit. The light weight, wide tread, 
short turn and low build of the 
power Hardies make them usuable 
where other sprayers would be im¬ 
possible. Write for catalog and

The RURAL NEW-YORKER 
The Apple-tree Tent Caterpillar 
Enclosed under separate cover I am 
sending specimens of what we found on 
several limbs of a peach tree. Would you 
examine and tell us what it is and what 
we should do to destroy it? m. n. 
Middletown, N. Y. 
Many insects have very marked “ups 
and downs” in their lives through a se¬ 
ries of years. The apple-tree tent-cater¬ 
pillar is a notable example of an insect 
that increases enormously and becomes 
exceedingly abundant for a period of 
four or five years, and then gradually 
diminishes in numbers until it almost dis¬ 
appears for a considerable period, when 
suddenly it becomes abundant again. In 
other words this insect may be “up” for 
a period of years, and then “down” for 
a time, and then up again, thus alter¬ 
nating in abundance and scarcity 
throughout a long period of time. Dur¬ 
ing the years from 1012-1916 this insect 
was enormously abundant in New York 
State and in New England. For the 
past few years scarcely a tent of the 
Egg Mass of the Apple-tree 
Tent Caterpillar 
caterpillars could be found until the past 
Summer, when they suddenly appeared 
again along the roadsides and fence rows. 
In July the moths lay their eggs in 
brown rings encircling small twigs, and 
these were what the correspondent, M. 
N-, sent. The egg-rings are about three- 
fourths of an inch long and varnished 
over so that they are not affected by the 
weather. They remain on the twigs un¬ 
til the following April or May. As the 
buds begin to swell with the first warm 
spell in the Spring the eggs hatch, and 
the caterpillars soon begin to spin white 
tents of silk in the crotches of the 
branches. The caterpillars eat ravenously, 
and grow very fast, increasing the size 
of their tents as they grow. If there are 
several colonies on a tree the branches 
may become full of their white ugly tents 
and the foliage may be completedly 
stripped from the tree. 
The apple-tree tent-caterpillars are 
partial to the wild cherry, and will se¬ 
lect the apple as the second best fool 
plant. They also attack plum, peach, 
thorn pear and various shade trees. 
They are controlled by collecting the 
egg-rings during the Fall, Winter and 
Spring, and burning them. School chil¬ 
dren are often enlisted in this work, and 
collect thousands of the rings. The cater¬ 
pillars may be destroyed by spraying the 
trees with arsenate of lead, 2% lbs. of 
the powdered lead to 100 gallons of wa¬ 
ter. Applications of the poison should 
be begun as soon as the buds begin to 
burst and the small tents are first seen, 
because the caterpillars are more easily 
poisoned when small. Two applications 
one week apart should be sufficient.

Chinese Fruit Trees 
Your publication has come with re¬ 
marks on “Starting Apple Trees in 
( hina, page 5o. Dr. John L. Nevins, 
the famous missionary in China, was 
from Central New York. He introduced 
manv varieties of deciduous fruits and 
grapevines into China. His garden was 
in Chefoo, Shantung Province. Before 
he died he turned it over to Christian 
Chinese. About 1890 I bought quite a 
variety of trees and vines from the own¬ 
ers. The list included apple trees. If the 
friend in 'China would apply to the 
American Presbyterian Mission in Chefoo 
he could learn what could be had from 
the garden. w. r. f.

Don’t let 
this happen to 
your apples 
Kill the aphids before they have a 
chance to do serious damage to fruit 
or trees. Spray with Hall’s Nicotine 
Sulphate. It contains 40 °/° pure Nico¬ 
tine—the deadliest aphis-poison known. 
Being a vegetable extract, it does 
not harm blossom, fruit or foliage; but 
it does kill aphids every time. 
A ten-pound tin makes 800 to 1100 
gallons of spray. The cost is less than 
2c a gallon. 
When spraying for scab, codling 
moth,etc., mix Hall’s Nicotine Sulphate 
with the solution and make one spray 
do double duty. 
Buy from your dealer. If he cannot supply 
you, send us your order along with his name. 
Note — Hall’s Nicotine Sulphate is also 
deadly effective against thrips, red bugs, leaf 
hoppers, psylla and many similar insects on 
fruit trees and truck crops.

Recommended by Experiment Stations 
for Increased Yields of Wheat 
Increased yields of from 5 to 10 bushels of wheat per acre are re¬ 
ported by five different state experiment stations following tests 
made with 
Nitrate of Soda 
Michigan reports a gain of 6.47 bushels resulting from a spring top 
dressing of 100 pounds of Nitrate of Soda per acre. Kentucky 
reports an increase of 103 ^ bushels with the same application. 
New Jersey used 160 pounds of Nitrate per acre and obtained 
a gain of 5.8 bushels of wheat and 925 pounds of straw, while the 
value of the crop was increased $9.03 per acre over the cost of 
the Nitrate. 
Delaware showed an increase of 4.6 bushels with an application 
of 125 pounds per acre. Virginia reported that an increase of 5 
bushels could be expected from the use of 100 pounds per acre. 
Except under unusual conditions I do not recommend more than 
100 pounds per acre. Full details of other tests and my own recom¬ 
mendations are given in my Free Bulletin Service covering wheat 
and all other important crops. I shall be glad to send these bulletins 
to anyone interested and ask that to identify this advertisement 
you list the number 2038.
