temperatures when subjected to repeated
shocks, led to the following unique test: A
number of newly cast test bars were sub
jected TO some 5000 taps from a hammer
upon one end, ana when these were com
pared as to strength with other untreated
bars from the same set they showed an
identically proportionate Increase in
strength as had been observed with the
bars cleaned in the tumbler. Numerous
other experiments made by Mr.. Outer
bridge on this line of inquiry confirmed the
interesting fact that substantial increase
of strength, amounting in some cases to
as much as 30 or 40 per cent, was exhibit

of the home of Gautama
Buddha have brought to light
buildings more ancient than any yet found
in India. 1t win be recollected chat a pillar
marking the site, and erected by the EN-
peror Asoka in the third century, was dis
covered accidentally three years ago. Since
then the place has been visited by antigua
ries, who report that it lies in the midst of
thick jungle, and is of vast extent. For
many years Kapilavastu, as the place was
called, has been eagerly sought for in vain.
1t was destroyed in Gautamas own life
time, and was a mass of ruins when it was
visited by distinguished party of Chinese
pilgrims in 40 A. d. KapilaVastu was the
capital of a small raja, whose son eau
tama was The actual birthplace of ihe
latter is known as the Lumbini Garden,
also marked by q column of Asoka, which
is now being eXcavated. A tumulus which
was found contains no less a relic than
bones of the Buddha himself. These were
inclosed in a wooden box, with an in
scription Of the same date as the pillars,
and strongly incased in a massive Golfer
cut out of a solid block of sandstone.
With the box were crystal vases of eX-
quisite workmanship, containing gold and
gems.
An exact determination of the distance
through which pipes, such as are used in
mines, may be relied upon for conveying
signals, has been made by Schale, and ex-
planned in the Zeitschrift fur Berg. From
this report, says the New York Sun, it
would appear that straight pipe systems
win carry the sound long way, but that
side branches are less reliable He made
experiments in Westphalian coal mines,
using sprinkler pipes put up to lay the
dust; these were mostly galvanized
wrought iron pipes, one to two inches in
diameter, suspended by wires or hooks
or placed in conduits, and connected by
flanges, with rubber packing, or fitted
into one another with hemp packing, the
branches generally joining under right an
piece it was found that the hands were
a better help; slowly spoken words thus
could be understood at the eXtremities of
straight pipes 1900 feet long, especially
when the pipes were firmly fixed. Whistle
signals were much less distinct; tapping
the pipes answered best, of course. Every
side branch decreases the efficiency. Yet
communication was fairly good, for in
stance, with a pipe 100 feet long, divided
into two side branches, the main pipe be-
ing further continued through a connec-
ton containing a valve to two other side
branches, each of the four branches hav-
ing a length of 700 feet.
An experiment in high voltage long
distance electric power transmission was
recently made at Ogden, Utah, to ascer-
tain the limits within which high voltage
currents might be used commercially The
experiment consisted in connecting the
Salt lake ends of the transmission lines
together and dividing the transformers
at Ogden, normally used for raising the
pressure of the current for transmission,
into step-up for the outgoing and step
down for the incoming. This made "a
complete transmission circuit of seventy
three miles over three No. ! B. & S. cop
per wires. One thousand horse power was
transmitted in this way, the voltage be
ing a times as high as 3O,000 The load
was composed Of three water tank resist
ances at the Ogden power house. BY
careful and repeated experiments with
watt meters at both ends it was shown
that this power was transmitted with the
loss OF only per cent including per
cent. loss in the two sets of transformers.
The lnductance drop was practically nil,
the capacity of the line being sufficient to
compensate for reactance loss. Using cur
rents at about 1000 volts 800 horsepower
in synchronous motors and lights was
operated at Salt Lake City for two days.
