usually resulting from moisture.
"A chain of Siemens steel, 100 yards
long and containing more than 5000
links, held together by $50 steel pins,
has beerf made at Hull, England. It's
estimated strength is sixty tons, and it
is believed to be the largest chain ever
made. q. = ,..,''.t = II

omizer and air moistener for cloth fac
tories, which, throws out moisture in a
mist SO fine that it is absorbed by the
air, and not even thersmallest drop ef
water falls upon machinery or fabrics.
The use of such a. continuance is. -yalua-

Count Hugo yon Eugenberg, of Ger
| many, is using the micro-telephone to
|. discover hidden springs. He buries in
the slope of a. hill several microphones
and connects each with a battery and
separate telephone. Then III the Silly
night he listens at the telephones and
hears the faintest, gurgle of the water
far beneath the surface, if there is any
to gurgle. The microphone plays the
part of hunters or savage's sensitive
ears, which have been known to detect
springs, unaided, at a considerable
depth. -Dea,,er Tribune. ~ aa - @g.. "a
"A s'chemicala lung' is the latest
thing proposed for the ventilation of
tunnels. It was lately tested in London
by fourteen scientists. ~ room fifteen
by eighteen feet was KEEP. for an hour at
"a temperature of 80 deg, and the air
was loaded with impurities. The men
of science were now called upon to en-,
ter, and the air was made still more i'm
pure by burning sulphur and carbonic
acid gas. Then the. sschemical lung"
or punkah, so called, measuring four by
two and half feet, was set in motion.
The temperature was soon reduced, to
IS deg. and the air freed from all impu-
rites Then-fat was burned to test the
machine for organic substances, and the
'slung' was started up just in time to
prevent the examining gentlemen from
running out for fresh air. 1t is proposed
to use the invention during the construc-
ton of the Channel tunnel.-N. Y. Sum-
