SPRAYING QUESTIONS. 
Stock Solution of Bordeaux. 
We are expecting to spray 15 acres of po¬ 
tatoes the coming season with Bordeaux Mix¬ 
ture, and would like some experienced potato 
grower to tell me about making a stock solu¬ 
tion sufficient to cover this acreage once. In 
other words, if it is possible to make, in 
one barrel, a solution of lime and in another 
barrel bluestone, in sufficient quantity so 
that, when diluted with right amount water, 
there will be enough to cover vines once. I 
would luce particulars about quantities of 
each ingredient needed for the season, and 
for the first spraying and any particulars 
about straining, etc. Also anything from 
others’ experience that would be likely to 
be of help in attaining a maximum yield. 
Vines usually grow very large. c. D. k. 
West Burlington, X. Y. 
It is possible to make enough Bor¬ 
deaux Mixture at once to spray the above 
acreage, but it would require an extreme¬ 
ly large mixing tank. Concentrated stock 
solutions of copper sulphate, one pound 
to each gallon water (dissolved by sus¬ 
pending in sack at surface of water), are 
often used, also a stock lime wash of a 
creamy consistency which will keep all 
season if kept covered with a little clear 
water. The 5-5-50 Bordeaux is generally 
recommended for potatoes, which means 
five pounds copper sulphate, five pounds 
of stone lime to 50 gallons of water. To 
prepare 50 gallons of Bordeaux Mixture 
as per above formula, fill a 50-gallon cask 
three-quarters full of water, add five 
gallons of the copper sulphate solution, 
and stir in enough of the lime wash to 
equal five pounds of stone lime. Stir 
well when adding the lime, and then test 
a little of the mixture in a saucer or 
can with a few drops of a 10 per cent 
solution of yellow prussiate of potash. If 
it shows a red brown color lime must be 
added until you get no color from the 
test. It is best to have a slight excess of 
lime than a deficiency. As nozzles of a 
smaller capacity than generally used for 
orchard work are best, great care should 
be taken in straining the Bordeaux. A 
strainer is made somewhat after style of 
diagram, the size of mesh being the same 
as the diameter of opening in nozzles. An 
inverted V-shaped strainer will strain 
mixtures that it would be impossible to 
get through a strainer with a flat horizon¬ 
tal sieve. One-quarter to one-half pound 
of Paris-green or its equivalent in some 
other form of poison should be added to 
50 gallons of Bordeaux when Potato bugs 
threaten. Commence spraying when po¬ 
tato vines are six inches high and repeat 
about every 10 days. 
Paris-Green in Bordeaux. 
On page 130 you have an article on spray¬ 
ing for Apple scab. Do you mean to say 
add the one-quarter pound Paris-green to the 
Bordeaux Mixture extra or not? I have 
Bordeaux Mixture as follows: Paris-green, 
one-half pound: blue vitriol, five pounds: 
new process lime, five pounds; water, 50 
gallons. I want to spray for leaf blight, Cod¬ 
ling moth and scab. What is the cause of 
my apples wilting? I. J. H. 
Cumberland, Md. 
The fungicide commonly known as Bor¬ 
deaux Mixture contains no Paris-green. 
On page 130 I stated that one-quarter to 
one-half pound of Paris-green could be 
added to each 50 gallons of Bordeaux 
Mixture for the purpose of combating 
Codling moth and leaf-eating insects. The 
formula you are using should be all right 
for leaf blight, Codling moth and Apple 
scab. It is somewhat stronger than will 
be generally used in New York State the 
coming season. Most growers prefer the 
stone lime to the so-called “new process” 
lime. You do not state if the apples were 
wilted at picking time, or have wilted in 
storage; if the latter, I should say it was 
caused by the apples being too freely ex¬ 
posed to warm, dry air. Apples seldom 
wilt if stored in double-head barrels and 
the air in storage room not kept too dry. 
Advice About Spray Outfit. 
I want your opinion as to spraying out¬ 
fits. Last year I planted about 1,700 fruit 
trees; peaches, apples, pears, cherries, etc. 
What sort of an outfit would you advise my 
purchasing? What would you do if It were 
yours? I want a good outfit, but I do not 
want to buy half a dozen before I get a 
good one. j. m. r. 
Natrona, Fa. 
The 1,700 trees of mixed planting can 
be easily sprayed the first few years with 
a good hand pump. You will need 
pump, suction hose, spray hose, exten¬ 
sion pipe and nozzles with both fine and 
coarse caps. This pump on a wagon 
or cart with a small tank or two casks 
of spray mixture is a cheap, light and 
serviceable outfit. A power sprayer will 
cost four to 10 times what the above out¬ 
fit will. b. d. v. B.

Potash liberally used 
as a fertilizer improves 
the quality, and hence 
the value of hops. 
Your fertilizer must 
contain at least io per 
cent, of actual 
Potash 
to produce hops of best quality. This 
is fully explained, along with other useful 
farm hints, in the “Farmer’s Guide.” We 
send it free.

WEEDER and CULTIVATOR 
Make sure of bigger crops by killing weeds 
at first shaving, keeping surface mellow and 
preserving moisture. Nothing like this imple¬ 
ment for such work. Particularly adapted to 
cultivation of corn, potatoes and beans because 
it narrows down to go between rows. Quickly 
and easily set for any width. Ask for book of 
many photographed field scenes ofweeder at 
work.

Make Plowing Easy 
By 
Using 
Wonder 
Plow 
Trucks. 
This truck will fit any beam, 
right or left, one or two horse, 
wood or steel plow. A boy can 
handle it with ease, most of the 
time without his hand on the 
plow. Regulates perfectly 
depth and width of furrow. Will balance plow in 
hard, dry, stony soil, and save a third of draft on 
horses. The plowman does not need to hold plow 
handles. Works perfectly in tall grass or weeds, 
turning them completely under. Thousands in use. 
If it does not do all of these things, you can 
send it back and we will not only return your 
money but pay the freight both ways.

everywhere. Retail price $5. Get special agents proposition.
