SCIENCE AND INDUSTRY.

Our product of salt, in 1890, was
s,776, 991 barrels, the supply coming
largely from Michigan and Western
New York.
Of the total American population
born of native parents, thirty-two per
cent. were earning wages when the
tenth census was taken. The p1 opor-
ton of bread-winners among our i'm
migrants is larger than among the
native population.
in 1890 the capital invested in the
United States in various manufactures
exceeded 81, 1000, 900, 900, while the
wages paid the employees of manufac-
tories had risen from 1878, 900, 900 to
81, 600 OOO OO0 the material employed
had increased from $3.50, 900, 900 to
nearly s., coo, 600 600, and the value of
the product from a tritie over $l,00O,-
600, 900 to nearly 50, 400 900, 900.
The aerat ton of the water of a large
storage reservoir is to be done by means
of compressed air, to be furnished from
an air-compressor on a small steam
boat to be placed on the reservoir. The
work is to be carried on only during
the hot weather the idea being to pre-
vent the development of unpleasant
odors or tastes from stagnation and
the growth of minute organisms.
DR. Paul Brisson, of Paris, claims
to have discovered the microbe of
old age. He says that it exists only in
the blood of old and decrepit men, and
when injected into the circulation of
young and healthy individual it pro-
duces all the signs of advanced age.
DR.. Brisson further announces that by
the injection of a certain serum into
the blood, these microbes can be de-
stroyed, and he says that man may live
indefinitely, provided the propagation
of the microbe be prevented and acct
dent be avoided.
An interesting experiment in turn
ing large farms into small holdings,
which may help to solve the agricul-
tural problem in England, was recent
~ completed in Dorsetshire. Sir
Robert Edgecombe, seven years ago,
bought farm of 343 acres, spent
money in building roads and wells,
divided itup into 25 holdings of from
to 80 acres, and offered them for sale,
payment to be made in ten equal an
nual installments. Purchasers were
readily found of all trades and classes,
eight only being agricultural laborers,
and all the ;nstallments, with slight
exceptions, have already been paid off.
Instead of a farmer and three laborers,
there are now % families of Is persons
on the land, which has increased in
value from G17O to 4313 a year.
Gas from Condensed Chemicals
Among the promised blessings is light
produced by the decomposition by air
and moisture of certain chemicals that
are compressed into tiny rolls or rods.
Upon being exposed to damp air, the
end of the rod slowly dissolves, gener-
ating a powerful, clear and not I'M
wholesome gas that can be piped
through a dwelling apd used after the
ordinary fashion. There is nothing in
the range of average wants that is
more needed than this. The lighting
problem, especially in suburbs locali-
ties, is a stupendous one to struggle
with. Small towns where gas is used
make the cost of such lighting almost
prohibitive. When one can have the
material for gas supplies as one of the
regular needs in an ordinary rod or
tube at so much per yard or pound, the
question of lighting will be robbed of
many of its unpleasant features.
