hopping and scrubbing floors by cleo

used in quarry work.
There are more adherents than
many suspect to the non-breakfast
theory. The two-meals-a-day folk be-
lieve that no work being done after
the late and hearty dinner, and little
tissue waste occurring during sleep,
the body has sufficient energy stored
from the evening meal to enable them
to perform the mornings work.
Cheap hand grenades may be made
by dissolving twenty pounds of COM
mon salt and ten pounds of, sal am
monlac in seven gallons Of water. Fill
quart bottles of thin glass with this
liquid and cork tightly. The bottle
should be thrown so as to break in
or near the flame in case of fire. The
breaking Of the bottle liberates gas.
and the heat of the fire generates more,
working its own destruction.
Bromiodide, one part; bromine, one
part; water, five parts. Thirty grains
OF this solution is said to be sufficient
to sterllize one quart of river water in
hVe minutes. If the water is very hard
or foul, the lime salts and ammonia
neutralize part Of the bromine. In
TINS case. add bromine solution until a
faint yellow color is obtained and per-
sists half minute. An equal amount
of per cent solution of ammonia neu-
tralizes the free bromice. When this
is done the water is clear.
An English journal records a num-
Der of cases of blindness from electri-
city within the last six weeks. It has
been predicted that if the present cleo
trio lamps continue in use weakness
OF sight will be produced in this gen.
Grafton. partial blindness in the next,
and total loss of sight in the third or
fourth generation. 1t has been sug-
gested that fuorescent tubes be adopt
ed These would fit around room like
a strip of moulding. 1t is claimed
that they would give strong, even
light, which would not harm the eye
sight and would cost no more than the
present incandescent and arc lamps.
An exceptionally healthy English
man, aged 81 years, had black mole
on his arm since birth. Three years
ago it was torn by the horn of sheep,
but quickly healed. He soon injured it
again and it enlarged to the size of a
finger tip. Six months later he again
bruised it and healing did not take
place rapidly. A few satellites ap-
peared. A physician excised the whole
affected area of skin. In five months
lump appeared in the axilla and was
promptly eXcised. Soon the surface of
the body was thickly sprinkled with
melanotic growths, ranging in depth,
size and color. A mole is potential
sarcoma and on showing the slightest
activity should be promptly and freely
excised.
Coventry and Birmingham, England,
are considered to have acquired all the
artistic skill attainable in the con-
struction of watches. The test of ex-
cellence in watch is that it obtain a
Kerr certificate. No watch has obtained
the 100 marks which signify peri :
ton, but Coventry has come nearest
with 80. The Kerr test is severe one.
The watch is tested in every position
by the day and hour. It is baked in
an oven and frozen in a pail. 1t must
make $4,000 vibrations an hour and
not vary second per week. A quar-
ter turn of it's time screws, millionth
of an inch, will make a difference of
twenty seconds day. 1t should only
be repaired by most skillful hands.
