A Georgia inventor has invented a
6reproof cotton bagging, the use Of
which will very much reduce the insur-
ance rates on cotton. It is called ''anti-
phlogan," and is said to be cheaper than
the jute or gunny-bagging now used.
To test the purity of water there has
been found no better or simpler way than
to fill clean pint bottle three-fourths
full of the water to be tested, and dis
solve in the water half a teaspoon
full of the purest sugar-loaf or granu-
lated will answer-cork the bottle, and
place it in warm place for two days. If
in twenty-four to forty eight hours the
water becomes cloudy or milky it is un-
fit for domestic use.
1t has been proved beyond all doubt
that waters which circulate or stand in
leaden pipes or vessels not only take up
particles of lead through mechanical
action due to friction, but attacks the
metal because of the affinity of several of
their constituents, the result being gem
orally lead carbonate. Minute quantities
of lead introduced into the system must
rank among the factors of an@mia and
defective nutrition in large towns.
The clectric light is being used to light
bakers ovens. A great difficulty has al
ways existed among bakers to get light
into their dark ovens so that the progress
of baking might be observed. Two in
candescent lamps, driven by Victoria
Brush machine, are placed inside an oven
where the temperature ranges from 400
to 500 degrees Fahrenheit. The oven

distinctly visible. The baker now never
need burn his bread or pastry.
Considering its extent, America is
better supplied by the clouds than Europe
and Africa. In the tropics of the old
world the annual rainfall is about seventy
seven inches, while in tropical South
America it is 155 inches. In the eastern
United States it is forty to fifty inches;
but west of the one hundredth meridian
to Sierra Nevada it is mostly twelveto six

Britain is thirty five inches that of France
twenty to .twenty-one inches but about
the Alps it is mostly thirty-five to fifty
inches. Farther from the coast, in
central Germany and Russia, it is only

gee, where over a small area the yearly
fall of rain is more than 610 inches, or
about tifty-one feet.
The process of swallowing food in
serpents is painfully slow and somewhat

limbs or molars to swallow its prey,
