Recent observation throws doubt
on the existence of the so-called fatigue
of metals. Two large iron links, one
used for forty years in a suspension
bridge at Kieff, and the other kept in
store since the building of the bridge.
were tested together, and were found
TO be of practically identical strength.
An officer in the bureau of the super
intendent of immigration at Washing
ton says that the present demand for
domestic servants is unprecedented.
They are for the most part German,
Swedish or Irish immigrants, and it is
now rare thing to find an American
girl in the kitchen.
The manufacture of the little Swed-
ish matches which are sold everywhere
so cheaply forms one of the great in
dustries of Sweden. Some idea of the
extent to which these matches are sent
ABROAD may be inferred from the fact

than the rest, the process of bleaching
sugar with clay was adopted.
A German inventor has devised q
new material which is intended as a
substitute for leather in many of its uses
This material consists of panels of
wood with wire netting between, the
whole being glued together under heavy
pressure. The sheets thus made are
said to be very tough and pliable, and
suited for making trunks and other
uses that require strength.
Many of the interesting remains of
Troy, which were eXcavated at such
pains by the efforts of the late DR..
Schliemann, have been stolen and de-
destroyed by the Turks and Arabs, and
some OF the most valuable stones used
to build their wrotched huts The guard
which was placed in charge of these
relics, after the death of Dr. Schliemann,
has been discontinued, and there is moth
ing to prevent the depredations of the
natives.
Hiram Maxim, the scientist and
electrician, says it is mistake to sup
pose that the discharge Of rife loaded
with smokeless powder is noiseless.
There is, says he, no such thing as
noiseless gunpowder. The report from
discharge of smokeless gunpowder is
much sharper and higher pitched than
that from black or ordinary gunpow-
der; it can not, however, be heard any
thing like SO far away. The recoil of
the piece is much less, also, with smoke
less DOyder
