Dusting Saves (1) Time, (2) Fruit, (3) Money 
a) With a Niagara you and a boy can protect 
5 acres of mature apple trees.or 4 acres of 
field crops in one hour. 
( 2 ) This means real protection for it enables you 
to cover a large acreage at the critical time. 
( 3 ) The Niagara Orchard Duster (illustrated) 
is simple, compact, sturdy and has few 
working parts. That means economy of 
upkeep. Its patented cylinder of brushes, 
its aluminum hopper, fan and fan housing, 
its Hyatt roller bearings mean long life and 
constant efficiency. Niagaras are most 
economical because they keep on doing 
their job properly year after year. 
It will pay you to call on the Niagara Dealer, 
or write us and find out just what model duster 
and what dusts are best for your use.

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 
2o 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.

Spraying Notes 
The San Jose Scale Again Demands 
Attention 
Fluctuating Conditions. —Nearly all 
insects have their “ups” and “downs.” 
With some insects these fluctuations in 
numbers seem more notable and con¬ 
spicuous than with others. For instance, 
the army worm after a great period of 
great abundance, passes out of sight and 
notice for several years,, and then sud¬ 
denly reappears again over much terri¬ 
tory and in great numbers. The common 
apple-tree tent-caterpillar is also notaole 
for similar habiis of alternate abundance 
and scarcity. The San Jose scale has 
perhaps not tyeen in this country long 
enough to develop such remarkable fluc- 
t ations as have the two insects just 
nertioned; but during the years from 
1915 to 1918, there was, in the East at 
least, a conspicuous falling off in num¬ 
bers of the scale and a decided lessen¬ 
ing in its injuriousness. We predict that 
these periods of “downs” in the case of 
the San Jose scale will become more 
and more frequent, and not so far apart, 
as the forces .of nature in this country 
concentrate more and more on this com¬ 
paratively newcomer. It must he remem¬ 
bered that this insect has been with us 
only about 45 years and that is a very 
short time in the life of the earth and 
the slowly-moving forces of nature. 
Immune Scale. —The San Jose scale 
shows evidence also of another very inter¬ 
esting development. In tbe Northwest, at 
Apple Specked icith Scale 
least, accumulating evidence seems to 
point to the fact that this insect is cap¬ 
able of developing strains or races that 
are immune to the effects of lime-sulphur. 
It is difficult to prove this tendency, but 
it is evident that where the scale was 
once satisfactorily controlled by spray¬ 
ing with lime-sulphur it is not now be¬ 
ing held in check with this material 
even when it is applied at the same 
strength as formerly, and with just as 
much care and thoroughness as in former 
years. In fact we have heard during the 
last few years much complaint from grow¬ 
ers in Arkansas, Illinois, and from a few 
in New York that lime-sulphur does not 
kill the scale as it used to do. Can it 
be that this notorious pest is really be¬ 
coming resistant to the effects of lime- 
sulphur, so that we shall have to look 
for a new material with which to fight 
it? Only prolonged observations and 
experiments during the coming years can 
answer this question. Growers in Ar- 
Kansas and Illinois have already begun 
to use oil sprays in place of lime-sul¬ 
phur, and apparently with much better 
success in controlling the scale. In New 
York, however, the problem of the scale 
does not seem quite so serious as it 
does in the Mississippi Valley; and this 
agrees with the characteristics of this 
insect, for it is a notable fact that the 
San Jose scale varies in different regions 
in the virulence of its injuries and in 
its resistance to spray mixtures. For 
example, Melander of Washington points 
out rliat the scale is much more difficult 
to control in the orchards about Clarks- 
ton in the Snake River Valley than in 
those in the region of Wenatchee in the 
Columbia River Valley. 
Procedure in New York the Coming 
Spring. —The San Jose scale in its at¬ 
tempt to return in abundant numbers 
may appear fairly uniformly over a whole 
orchard ; but perhaps more often it will 
Spray thoroughly and 
harvest clean fruit 
In hustling to spray your trees at just 
the right time, you can be thorough with¬ 
out being slow. Use a Hercules-powered 
sprayer and you’ll get through quicker. 
7 he Hercules engine puts thoroughness 
with speed in the job; pumps spray stead¬ 
ily lor hours without rest, at 200 to 250 
lbs. pressure. It is the same rugged and 
trouble-proof Hercules engine that is the 
standard farm engine of the world. 
Farm machinery that is equipped with 
a Hercules engine by the manufacturer 
will get your work done faster. Manu¬ 
facturers know that no machine can pos¬ 
sibly be better than its power plant. 7 hey 
use the best of power; Hercules engines. 
Saw rigs, concrete mixers, feed cutters, 
pumps, hoists—many machines are now 
sold complete with Hercules engines. 
They range from 1 % H P. up.
