The wheat crop of New South Wales
yielded IL bushels per acre, rather less
than the average of the past 80 years.
Inc total area cropped was BIS, PCS

quirements are 1850, 600 bushels. exclu.
sive OF seed, consequently, over 5000, 900
bushels must be imported.
The great Alta irrigation district
system OF canals has been completed in
california, and is running full of water.
practically irrigating one hundred and
thirty thousand acres of land. Five hum
1red miles OF canals and distributing
bitches are in operation.
There are no great wooden factories
IN Egypt, but the looms are scattered
In small numbers over the country.
According to Mr.. Felix Mengin. in his
historic Sommaire de rEgypte. 1923
IS, published in 1899. there were in
Egypt, in 1888, 1900 looms for weaving
wooden stuffs. These stuffs were used
to dress the fellahs and the sailors and
Tor bed covers, etc The coarse woods
OF upper Egypt were chiefly used for
those purposes, not being suitable for
any other use.-Pittsburgh Dispatch.
When increased work is thrown
upon the heart during active muscular
exertion, endurance of fatigue is limited
mainly by the limited power of the
heart to continue supplying the in
creased amount of blood which is re.
quired by the acting voluntary muscles.
Luxuries which are forbidden or limited
in training" and which are known TO
hinder prolonged exertion, such as
water, alcohol, tobacco, directly weaken
the force Of the hearts contractions,
and so weaken the hearts power to
send blood to working muscles.
A recent test of brick made by the
dry clay process at WATERFOWL arsenal.
according to Paving, showed an aver.
age compressive strength of 3.912
pounds per square inch. In one in
stance it reached 4,973 pounds per
square inch. A test was made at the
same place on a fancy pressed brick
The first crack developed at a pressure
of sos, 900 pounds and the brick crushed
at 564, 900 pounds, or 11,13O pounds Der
square inch. This indicates almost as
great compressive strength as granite
paving blocks, which is from Il, 900 to
10000 pounds per square inch.
"A German inventor has devised a
means OF producing light superior in
strength to either oil or electricity. 1t
is by means of air driven through
pumice-stone, the latter having been
impregnated with benzine. The ben
zine gas thus obtained is then carried
through fine magnesium powder, and
proceeds upward through a pipe to be
consumed in small fame of claimed
100000 candle-power. The apparatus
consists of blast engine for driving
the air through the pumice, and num-
Der of other accessories, all of which
take up but small space.-English

The horse power of a whale has
been made a subject of study by the
eminent anatomist, Sir William Turner,
of the University of Edinburg, Scotland.
in conjunction with the equally eminent
Glasgow shipbuilder, Mr. John Hender-
son. The size and dimension of a great |
Inner stranded several years ago on the |
shore at Longriddy furnished the neces-
sary data for computation of the
power necessary to propcl it at speed
Of twelve miles an hour This whale |
measured eighty feet in length, twenty
feet across at the fianges of the tail. and
weighed seventy-four tons. To attain
speed OF twelve miles per hour it was
calculated that one hundred and forty
i've borse power was necessary.
Eastern farmers, who have album.
liant supplies of water for crops and
very other purpose, by rainfall and
springs and rivers, know little of what
he problem of a water supply means to
he farmers in the dry belts and arid
regions of the west. Some idea of the
abor involved in securing water for
irrigation may be gathered from the fol-
owing figures of the four largest dams
last year: The Walnut Grove
lam, near Prescott, Ariz., 40 feet high.
nclosing $50 acres, and having a capa-
ity of 1000, 600, 900 gallons; the MERGED
lam, in central California, one mile
ong, go feet high. inclosing $50 acres,
md storing $500, 600, 900 gallons: the
'weetwater river dam, near San Diego,
al. 90 feet high, 725 acres, storage ca
'acity 5000, 100000 gallons, and the
Bear Valley dam, in San Bernardinc
ounty, Cal. 60 feet high. inclosing
ESQ acres, and holding 10000, 600, 600
allons of water.-N. Y. Sun.
