SCIENTIFIC AND PRACTICAL INFORM
ALTON.


Mr.. Lick has fixed on Mount Hamilton, in
Santa Clara county, Cal, as the most eligible
site for the establishment of the observatory
in which tie great telescope is to be located.
and he has notified the county supervisors
that he will begin the erection at once, II they
will construct road to the summit of the
mountain. As Mr.. Lick offers to advance the
necessary money to begin work on the road,
and accept its bonds in payment, it is proba-
BILE that his proposals will be adopted, and
hence there is an excellent prospect Of the
much talked of telescope becoming ere long
an accomplished fact
Mount FL .miIton is 444S feet high. The
summit is higher than any land within fifty
miles. and consequently below the level of the
plane of the observatory, which, in an astro-
nomical point of view, is the desideratum
sought. The beautiful valley of San Jose,
the snowy ridge of the Sierra Nevada, and a
boundless area of mountain scenery are in
the scope of vision, and the elevation is SO
high as to be above the fogs of summer, and
| is not SO high as to be much disturbed by the
storms of winter.
| IMPROVED SUGAR MACHINERY.
| Messrs Morris, iasker j. Co., Of Philadel-
phis, are now shipping large amount OF ma
chinery to be used in Louisiana in new pro-
cess of manufacturing cane sugar. The meth
cd is what is known as the diffusion process,
as distinguished from the maceration process,
which is that of all previously constructed
sugar machinery. The cane is passed between
rollers by the old method and the juice
squeezed out. In the new, the cane is sliced
| aud the saccharine matter is dissolved out
OF it.
PARLoR MAGIC.
The following beautiful experiment in
instantaneous capitalization is given by Peli-
got in La Nature: Dissolve $50 parts, by
1 ~ - I,.h.t 1f IN,
boiling water, and gently pour it into tall
test glass so as to half fill it, keeping the sou
ton warm by placing the glass in hot water
Dissolve 100 parts by weight, sodic acetate
| in Is parts hot water, and carefully pour it
into the same glass; the latter will form an
everything layer on the surface of the former,
and will not mix with it. When cool there
will be two supersaturated solutions. Ii
crystal of sodic hyposulphite be attached to a
thread and carefully passed into the glass. it
will traverse the acetate solution without dis
turbing it, but, on reaching the hyposulphite
solution, will cause the latter to crystalize
instantaneously in large rhomboidal prisms
With oblque terminal faces. When the lower
solution is completely crystalized, crystal of
sodic acetate, similarly lowered into the
upper solution, will cause it to crystalize in
oolique rhombic prisms. The appearance
of the two diff 4rent kinds Of crystals will not
fail to astonish those not acquain! led with this
class of experiments.
EPIzooTIc IN HORSES.
This disease, that swept over this entire
country and proved so serious in the tall of
1872, is appearing again this fall, though
probably in a milder form. Nearly all the
horses of this and other cities are affected
with it already, and it is certain to spread to
the country very soon. Horses that are in
good condition will suffer the least from its
attack. LIS first symptom is slight cough,
which gradually becomes more frequent and
severe, accompanied with running at the nose
and swelling of the throat between the jaw
bones Horses that are in good heart and are
properly taken care of will probably only be
slightly affected
A writer in the Ohio Farmer advises the
sim plest treatment possible Keep the horses
in a warm. comfortable, clean, and we'll VEN
tilated stable, blanketed in wet, cold weather !;
feed we'll with oats and sweet hay (corn is too
heating,) with good bran mash once day !;
the only medicine needed is to thoroughly
rub the throat with some good liniment if it
should become much swollen, and be very
| careful not to let them take cold. A little ex-
ercise every day at light work or careful driv-
ing, we deem beneficial but any violent
exercise, or anything approaching over exer-
ton, will be almost certain to produce serious
results.
TIE aim should be to keep the horse in as
strong heart as possible, and nature will soon
work out the disease. The usual term of this
distressing and destructive malady is from
twelve to twenty days.
COMMON SENSE VENTILATION.
"The best practical statement have met
about ventilation" says Colonel Waring in
the last atlantic, "was contained in the re-
mark of mining engineer in Pennsylvania:
Air is like rope; you can pull it better than
you can push it, All mechanical appliances
for pushing air into room or house are
Disappointing What we need to do is to pull
out the vitiated air already in the room; the
fresh supply will take care of itself if means
for its admission are provided 1t has been
usual to withdraw the air through openings
near the ceiling, that is, to carry off the
warmer and therefore lighter portions,
lie .ving the colder strata at the bottom of the
room, with their gradual accumulation of
cooled carbonic acid undisturbed. Much the
better plan would be to draw this lower air
out from point near the floor, allowing the
upper and warmer portions to descend and
take it's place. An open fire, with large
chimney throat, is the best ventilator for any
room; the one-half or two-thrds Of the heat
carried up the chimney is the price paid for
immunity from disease; and large though
this seems, from it's daily draft on the wood
with doctors bills and the loss of strength
and efficiency that invariably result from liv-
ing in unventilated apartments. Scientific

In preparing lard for the market, it should
first be cut into pieces about the size of
walnut, and these should be allowed to stand
in water for half an hour. Then work the
material with the hands in five or six success
sive portions of water Next pour Oft the
water, melt the lard in water bath, and strain
through fine linen. In the first straining it
will be impossible to get rid of all the water;
50 that after cooling and draining, it will be
necessary to remelt the lard and finally to FL
ter it through paper in warm closet.
good cheap paint for barns and outhouses
is made as follows: Put bushel of good lime
in clean barrel, and aud sufficient water to
make thin whitewash; stir it we'll with a
