nish about thirty pounds of crude sui.
| phate, the present value of which is
about G12 per ton, and there being TO-

are produced.
In the course of an investigation,
part of which has already been com
municated to the Royal society, Prof.
Roberts-Austen has discovered the most
brilliantly colored alloy as yet known.
1t has a rich purple color, and bright
ruby tints are obtained when light is re-
| fiected from one surface of the alloy to
another. 1t contains about seventy
per cent. of gold, the rest of the alloy
being aluminium.-N. Y. Ledger.
Flinders Petrie has made another
find in Egypt, at Maydum, where he
has unearthed the oldest Egyptian tenn
pie of which there is any knowledge,
and the only pyramid temple yet dis
covered. 1t was buried under forty
feet of rubbish and belongs to the old
empire. Hieratic inscriptions in black
paint within the cham bcrs fix the name
of the builder as Senefern, a king con-
Meeting the third and fourth dynasties.
"A magnet carried by Newton in
finger ring is said to have been capable
of raising 746 grains, or about $50 times
it's own weight of grains, and to have
been much admired in consequence. A
magnet formdrly belonging to Sir John
Leslie, and now in the physical collec
ton at Edinburg, has still greater
power, however, weighing 80 grains
and being able to support 1850 grains.

The majority of people die sooner
than they should. George f. Warner,
ir, says: "Disease is not consequence
of life; it is due to unnatural conditions
of living-to neglect, abuse and want"
And Dr. Stephen Smith says: Man is
born to health and longevity; disease is
abnormal and death, except from old
age, is accidental, and both are pre-
ventable by human agencies"
Large quantities of onions are
brought to this country from Egypt, as
New York in a single week. They are
not equal to the onions grown in this
country, being small and yellow, but
the price in Egypt is 50 low that, after
adding freight charges ard a duty of
forty cents bushel, they are sold here
for two dollars or two dollars and
half bag of nearly two bushels.
The mining departments of the min
istries of imperial property and of the
interior have sent three engineers to
America to study the methods by which
gold is worked out in the mines of Ari-
iona, Colorado, Nevada, California and
Utah. The yield of the Russian gold
mines has been very poor of late, and
the raising of the price of labor as well
as the rising of Russian values in the
foreign markets has made the mining
of gold almost improbable. 1t is be-
lieved that the introduction of American
methods of mining will improve the
miners trade.
The most important improvements

States of late years have been in sur
gerry in its various branches. This
country has led the way in the legation
of some of the larger arteries. in the re-

culiar to women and of spinal affec-
tions, as well as deformities of various
kinds Above all, we We're the first to

while for 1850, the value was only 81, 7S0,

So, 035,66 or 1866 per cent. There

whom were paid in wages S., $50.
The total expense of producing sand
stone in 1889 was SS,13O,295. and the
total capital invested S17,776, 467 of
which ST., sol, 100 was invested in land.
Oregon has only two quarries producing
in 1889 80, 900 cubic feet, valued at So, 424.
There are but two states quarrying less
than Oregon - New Hampshire and
Idaho Washington has five quarries,
producing SAC, O69 cubic feet, valued at
S15, 936.
