pearl-ash, and % pounds of phosphate
of soda, mix we'll, then add 400 pounds
ground bone, % pounds best Peruvian
guano. and $50 pounds ground plaster.
Mix the whole thoroughly, throw on a
pile for 48 hours, and it is fit for use.
If it is to be used for potatoes in dis
tricts where potato-bugs are numerous,
five gallons sulphuric acid may be sprin-
kled over the mass. Care must be Ia
ken not to use the acid in a confined
place, as the fumes are bad for the
health. If it is spilled on the floor, do
not throw water on it, as it generates
great heat when in contact with water.
Sulphuric acid sprinkled on the ground
will kill bugs of any kind, and its fumes
are especially fatal to the potato-bug.
TESTING STEAM B OnERs.-It is gen.
orally believed that steam boilers be-
come weakened (for resistance to inter
nal pressure) after continued use from
various known and unknown causes, so
that the engineer cannot judge of the
pressure to which his boiler can be
worked with safety. But this he may
determine by a very simple process and
means which are always at his command.
1t is as follows: Let the DO Ter be filled
entirely full of cold water even to the
throttle and safety-valves, and all closed
tight to prevent any escape. Now, by
lighting a fire under the BOILER, the wa
ter will gradually expand and produce
a pressure sufficient to even rupture the
iron before the temperature of the wa
ter has reached the boiling point. While
the pressure is increasing, let the steam
guage or pressure indicator be watched ;
and when the test pressure (Which may
be twice or more as great as the work
ing pressure) is reached, portion of
the water may be allowed to escape and
the pressure reduced. The pressure re-
suits from the fact that water is ex-
banded by heat more than iron. The
process above given is attended with as
much safety as the use of the hydro
static press, unless the water be heated
above 212 deg, which would not be re-
quired unless the boiler leaks. Below
this temperature no disastrous conse-
quences would follow, even if the boil
er should be torn asunder.
COLD FEET.-Why DO the feet become
so cold and benumbed? For answer
we may say thatamong the causes of cold
feet are tight garters, tight stockings,
and tight shoes, with, as the basis,
sluggish circulation of the blood and
low tone of vitality. Tight carriers and
tight shoes impede the circulation of
the blood, preventing the warm life cur
rents from keeping up the natural tenn
perature of the extremities. Tight lac
ing and corsets, also, have something
to do with causing cold feet and hot
head. Wear good sized lambs wool
stockings, or cotton if you prefer, and
instead of using carriers, fasten the
stockings to your drawers with a loop
and button; wear easy shoes or boots;
dress the person prOperly-never tight
ty-and exercise the body vigorously by
brisk walk or a lively run for ten or
fifteen minutes, and your feet will soon
come into comfortable condition. OF
course they should be washed on rising
in the morning, when the hands, face
and person receive their quick and tonic
ablutiOn. Simply wet the skin and
wipe dry with a soft towel, and then
rub vigorously for five minutes with
the hands. Do this regularly, and you
will have no more trouble with cold
feet. On retiring at night, should the
feet not be warm, they should be wrung,
squeezed and rubbed till ''all- aglow"
with currents of living blood, ana the
feet will be warm. Invalids may use a
bottle of warm water to their feet,
rather than lie awake in the semi-tor-
ture of cold feet. Some put cayenne
inItheir shoes to excite circulation; some
dance few moments before retiring at
night others battle their cold feet in
hot water. But we have given the
cause of the remedy above, and neither
pepper or medicines need he used for the
purpose. Never go to bed with cold
feet.-Science Of Health.
