fully understood, but the results are fa¬ 
vorable. 
But it is such an inert body and so in¬ 
soluble that for prompt results you might 
better depend on the carbonate and, still 
better, on the hydrated lime. These, if 
used in proper amounts, will change the 
nature of the soil, but some of your sticky 
Western soils are almost beyond hope 
unless you can get the lime pretty cheap. 
You can get sulphur into the soil quicker 
and better by adding it; the value is not 
Soap in Water Glass 
By accident a small quantity of per¬ 
fectly clean soapy water was>thrown into 
our water-glass solution. Will the eggs 
save and will it be all right? j. w.

All may be well, but personally we 
would not take a chance, as the eggs are 
worth a lot more than new solution.

Scratches on Leather 
A leather - covered davenport was 
scratched in moving. What will take out 
the marks? mbs. w. J. w. 
Dover, N. J. 
This is a very difficult matter to de¬ 
cide, as so much depends on the kind of 
leather and the way it was originally 
finished. Most fancy leathers are sur¬ 
faced by machinery, and, of course, the 
scratches go more or less below’ the sur¬ 
face. Polishing with a suitable abrasive, 
to renew the surface in general, and fin¬ 
ishing with beeswax in turpentine seems 
to offer the best chance of success, but 
you may have to go over the whole sur¬ 
face in order to get a uniform finish. If 
any reader has a specific remedy, we 
would be glad to have it. 
Gypsum in Place of Lime 
Some dealers are offering “agricultural 
gypsum” for use instead of lime, claiming 
it is of more value on account of the sul¬ 
phur it contains. How will the effect on 
the soil differ, and will the change in 
chemical composition of the soil be accom¬ 
panied by a change in the mechanical 
condition? S. M. B. 
South Dakota. 
The sulphur in the sulphate of lime, 
gypsum, will be valuable if the plants can 
get at it. and that depends on so many 
factors that no one can surely say what 
will be the result? The sulphate of lime 
ought to be very much cheaper than the 
hydrated lime, as it is merely a natural 
rock, ground, and should be cheaper than 
ground limestone; but that is largely a 
matter of freight rates. “Land plaster.” 
which is another name for the same stuff, 
has had a use for many years; it has been 
more popular than at present; now the 
swing seems to be again in its favor. 
yet proved. The Lipman scheme is to 
add the sulphur to the manure with the 
ground phosphate rock and depend on a 
rather complicated bacterial action to 
render both available. The action is not

The one and only thing for you is car¬ 
bon tetrachloride, which is sold in fancy 
June 5, 1920 
containers under fancy names. At whole¬ 
sale it is now sold at 10 or 12 cents a 
pound, and a drug or chemical house, or 
even a paint dealer, will get it for you, 
or perhaps your Grange purchasing agent 
can get it at reasonable price. It can 
neither burn nor freeze if you will add 
about 10 per cent "of naphtha, and this 
last will not help the fire, if the stuff is 
used, but will help the tetrachloride put 
the fire out. as it helps to spread the 
vapor. It might be worth while to get 
some of the regular outfits, but you can 
get the effect from the regular glass 
“grenades” filled by yourselves, or from 
glass bottles, well corked, in both cases, 
and with a little wax melted over the 
corks to prevent slow loss. 
Luminous Oil 
Can you tell me how to make luminous 
oil. sometimes used for fish bait? b. s. 
Jaffrey, N. II. 
If you will take a bit of yellow phos¬ 
phorus, which must be fresh, say about 
the size of a pea, and put in a dry bottle, 
and add to it about two ounces of castor 
oil, and then warm in water a little above 
blood heat, and then shake hard till cool, 
repeating the process till the phosphorus 
seems to have about gone, you will have 
a bottle of oil which will glow every time 
you let in air, and will continue to glow 
till the oxygen of the air is taken up. 
You will also have a very noisonous and 
very dangerous oil. and it may be against 
the law in your State to use that kind 
of bait; but, then, that is your lookout. 
It is possible that sweet oil will do as 
well or better than the castor; none hap¬ 
pened to be at hand to try. But you 
must take the greatest care with all these 
phosphorus mixtures, and with phos¬ 
phorus itself. Cut it under water and 
burn up what you have left. It docs not 
pay to keep it, as it will slowly turn to 
the other form which is no use.

COVERS MORE THAN YOU ADVERTISE 
Morrisville, Vt. 
I have used Devoe paints for many years. They cover more than you 
advertise and stand every test. Seventeen years ago a painter estimated 
10 gallons for a house and had enough left for another coat, which was 
applied ten years after the first two. It was Devoe, and this impressed 
me eo much that I have used Devoe ever since.

developed spark-plug trouble. The best assurance 
against this is to use Bethlehem Spark Plugs. 
Consider Bethlehem construction. The mica in the 
Bethlehem de Luxe Tractor Plug is wrapped around 
the center spindle, then reinforced with mica washers, 
to make the plug stand the heavy strains put on it 
by tractor operation. 
The great International Harvester Company, after 
exhaustive tests, has adopted Bethlehem Spark Plugs 
as standard equipment. You will find Bethlehem 
Automobile and Truck Plugs equally dependable. 
Studebaker and Marmon find them the best standard 
equipment. So do 48 other manufacturers.
