The two objects of spraying, are to kill insects and 
to prevent blight. 
Arsenate of lead in the right amount, blown on dry 
or sprayed on in solution, is the one chemical that 
will most effectively kill leaf-eating insects without 
injury to plants or foliage. 
Bordeaux Mixture is the great preventive and con¬ 
troller of blight and other fungus diseases. 
Insects can be killed after they appear. Fungus 
must be prevented by advance and continuous spray¬ 
ing. If fungus appears it can be controlled. 
You take the guesswork out of spraying when you 
use Hexpo. It is a wonderful combination of Arsenate 
of Lead and Bordeaux Mixture produced by most 
modern scientific methods. 
It comes in finely divided, fluffy, powdered form. 
No complex formula to follow. No muss and fuss with 
pastes. No preliminary stirring. No paying freight 
on water. 
Hexpo is blown on plants dry or sprayed in a water 
solution. To make the solution, you pour a quantity 
(according to directions on every package) into water. 
It mixes immediately and sprays evenly without 
constant stirring. 
Hexpo is cheaper and easier to use than home mix¬ 
tures—or any prepared insecticide and fungicide. 
Goes three times as far as inconvenient pastes. Keeps 
indefinitely and can not dry out or deteriorate. Put 
up in 1-lb., 5-lb. and 10-lb. sift proof cartons; also in 
25, 50, 100 and 200-lb. drums. 
If not at your hardware, seed or drug dealer, send 
for sample—1 pound carton— 75c postpaid,

Ice Saw with Sprocket Chain 
I have a circular ice saw that I wish 
to run with a sprocket chain, but after 
reading your articles on page 154 I am 
wondering if it will work. 1 have a 
roller chain, the rollers are % iu. long 
and % in. chain. I have a nine-tooth 
sprocket to put on the engine, a 5 II.I*, 
marine engine with a normal speed of 
700. and a 12 -tooth sprocket to go on the 
saw arbor These sprockets are cut from 
steel. Will the chain and sprockets stand 
the tune of 700, or would I better use a 
countershaft between engine and saw. 
and , run a belt from engine to shaft and 
chain from shaft to saw? I used a lighter 
chain last year on a 3 H.P. engine run¬ 
ning about 300 revolutions per minute, 
and it went well. J. H. T. 
Milton. Yt. 
As far as the speed goes I do not think 
that you would have any great difficulty 
in using the chain, provided the chain and 
sprockets have the same pitch and the 
shafts are correctly lined up. My ob¬ 
jection to the use of the chain and 
sprocket drive for the pole saw, and I 
think that this is the item to which you 
refer, was not based on speed but rather 
inflexibility. It does not furnish an elas¬ 
tic enough drive. The pole saw as well 
as the engine is usually fitted with a 
heavy balance wheel. Now if these are 
connected by chain or gearing and run at 
a high speed there is danger of s&rious 
breakage if the saw is suddenly checked 
in a stick that is being sawed as is likely 
to be the case. They would better be con¬ 
nected by a more flexible drive, as a belt 
which will permit a little slipping in a 
case like this and prevent breakage. The 
slipping of a belt under a sudden stress 
relieves a machine of many strains and 
often prevents serious breakage in cases 
where a machine is subject to intermittent 
loads, as in the case of the pole saw 
In the case of the ice saw the condition 
is different, and the load carried is a more 
uniform one ; however, even in this case, 
I would prefer the belt drive, for the 
reasons stated, if it can be so protected 
that it will not become inoperative be¬ 
cause of ice and snow Railroad com¬ 
panies get around this difficulty in their 
belted dynamo drive underneath tin* car, 
by using a wide belt for the power trans¬ 
mitted, keeping it under uniform tension 
bv means of a spring, and in some cases 
using a perforated belt. R. H. s. 
Charging 
Battery from 
Plant 
Home Electric 
We have a farm electrical installation, 
also an automobile. The starting and 
lighting battery of the latter needs occa¬ 
sional charging. Our electric plant is 32 
volts. Can we charge our auto battery, 
and how? Would we have to renew 
liquid also? Is there any reason why 
battery charged from our plant should 
not be done as effectively and give as 
much service as being charged from city 
current? w. F. M. 
Furniss, Pa. 
do not say so, it

to a point where the increased service 
obtained may pay for a good many re¬ 
charge.., and unless a man has consider¬ 
able skill in the care of batteries and the 
time to exercise this skill I am a little 
doubtful as to the advisability of home 
charging. With the long driving days of 
Summer (it is a noticeable fact, though, 
that most of the drives made by the far¬ 
mer’s pleasure car are at night, even with 
the daylight-saving law in effect) a bat¬ 
tery in good condition should seldom get 
run down and, as stated above, if a 
service station is a service station in fact 
as well as name a charging fee seems a 
good occasional investment. K. ii. s.

Sinking Well in Quicksand 
About 20 years ago 1 helped put a well 
down in quicksand. This well is still giv¬ 
ing good service, furnishing water for 
about 12 head of cattle and horses since 
that time. We went at it as follows: 
Dug a well 10 feet in diameter through 
the free sand to the quicksand, a depth of 
about 12 or 14 feet When this was 
reached we built a circular curb nine 
feet in diameter and eight feet in height. 
As I remember, we sunk this about seven 
feet, digging the sand out from the inside; 
had to load it well to keep it going down 
as we dug. We then built up a stone 
curb inside the wooden one, to the top of 
the wooden curb. Twenty-four-inch vit¬ 
rified tile were placed in the center of the 
well, which now measured about seven 
feet iu diameter. The space around the 
Although 
probable that the battery of your car is 
of the ordinary six-volt type. To charge 
this then from your 32-volt system a re¬ 
sistance should be added in the line so 
that the electric pressure or voltage is 
reduced. To accomplish this one of the 
charging rheostats or resistance units as 
they are variously called by the concerns 
making them should be added to control 
the current to the car batteries. It is 
likely that a homemade resistance could 
be made that would work satisfactorily, 
but those retailed by reliable home-light¬ 
ing companies cost only about .$7 and are 
neat and convenient. Communication 
with the firm manufacturing your plant 
would secure particulars as to the par¬ 
ticular kind necessary with their gener¬ 
ator and system. 
Unless the electrolyte has boeu spilled 
from a storage cell or other accident 
has happened distilled water, which can 
bo obtained at any drug store, is all that 
is required as an addition to the liquid 
already in the cell. This is simply pure 
water; and rain water caught in a clean 
earthen dish iu the open in the midst of 
a shower will generally be found satis¬ 
factory. The dish must be so placed, 
however, that no water will get into it 
by spattering or otherwise, that docs not 
fall direct from the clouds. The lowering 
the cells is usually caused 
and as the water is the 
the electrolyte that evap- 
only part that needs re- 
through accident it be- 
to add chemicals the ad¬ 
vice of the company making the batteries 
should be obtained 
To my mind the chief factors against 
charging one’s own batteries arc' the 
time required and the lack of expert ad¬ 
vice and oversight. In purchasing an 
automobile battery a certain amount of 
expert advice is purchased with it It 
is paid for at the time of buying the car, 
and is obtainable at any number of serv¬ 
ice stations scattered throughout the 
country An automobile battery is a far 
different proposition from the battery or 
a home lighting plant and works und-'r 
more severe conditions, rendennff its life 
much shorter. Expert oversight and serv¬ 
ice by correcting troubles 
velop may extend the life 
tile, about 30 inches, was now filled in 
with stone to top of curb. Over this was 
placed about two inches of concrete to 
keep out surface water and dirt. The 
tile was extended to grade and filled in 
around with the dirt taken out. The idea 
was to have a large body of water which 
would be lowered very slowly, thus not 
set the quicksand in motion every time a 
pail of water was pumped. This well has 
never been dry, nor has it been cleaned 
out that I know of. w. F.

Changing Mandrel on Saw Rig 
I have a saw rig with a right-hand 
mandrel, and as the engine pulley is on 
its left side I have to set the saw frame 
to the left, instead of directly in front, 
where it would have to be set if it is 
mounted. If I could change ends with 
the mandrel that would remedy the trou¬ 
ble, but I am told by mechanics the nut 
on the saw would loosen, as it would on 
a wagon if it were run backwards. Can 
you suggest a way out of the difficulty?

' of the engine. An 
__ „_ engiue may show 
this to be possible in your case. Even if 
the crank shaft does not project for this 
purpose it may be possible to have a 
pulley built up of wood which can be 
bolted to the fl,v wheel through holes 
drilled in the spokes. These holes may 
be centered accurately by holding a pencil 
or scratch-awl firmly against some part 
of the frame of the machine and letting 
it project just enough to mark the spokes 
s’ightly as the wheel is slowly turned 
This can be done, of course, only in cases 
where the pulley can be so applied that 
it does not interfere in any way with the 
governor, fuel pump or other part of the 
engine’s mechanism. 
Another alternative would be to turn 
the engine around on the truck, letting it 
face the other way. and using a crossed 
belt to drive the saw mandrel. This would 
bring the pulley both on the same side 
and still preserve the direction of rota¬ 
tion of the saw. As suggested, the saw 
must run in such a direction that the nut. 
would be tightened if the saw should slip 
between the collars holding it In othei 
words, turning the saw backward while 
the mandrel is held stationary should 
tighten the nut. R. H. s.
