A crane capable OF lifting weight
OF AT tons Is IN course Of construction
at Hamburg. II will be the largest
machine OF the kind on the contin-
emf Of Europe, that OF Antwerp
coming next with lifting power Of
100 tons.
When caoutchouc tubes are badly
vulcanlzed the experience Of M, Linz
ousIn leads him 10 say that thoy are
very dangerous in some chemical
operations, the presence Of sulphur
and Of antlmony sulphlde rendering
them especially 80 In the preparation
Of oxygen gas.
Black marble may thus be polished.
Wash the marble with soap and warm
water, and when IL Is dry rub II well
with furniture paste or French polish,
and then rub It over with an old silk
handkerchief. After two or three
trials tho marble will become quite
bright.
To mako pulp from wood or other
vegetable matter Reoul Hlcket flrst
oommlnutes the material and then
treats the powder with concentrated
sulphurous acid and water, under a
pressure ci Ave atmospheres, and at
temperatures ranging from rs degrees
TO so degrees CentIgrade.
Bronze may DO renovated and re-
colored by the use Of q mixture OF
one part Of muriatIc acid with two
parts Of water. After tho aatIcls is
freed from all grease and dirt the dill
uted acid 10 carefully applied with a
cloth. When the solution 10 dry the
Grticle Is well polished with fne
olive oil.
If. Delaurler has invented an cleo
trio lamp having for its essential
feature hammer which carries one oi
the carbous and receives q rapid re-
cIprocatIng motion from coll through h
which an intermittent current passes
Sparks caused by the alternate con-
tact and separation Of the carbons
produce tho effect OF a continuous
light.
The French Government are hav.
Ing constructed abroad large aud
costly special machine tools 10 aid Ia
the construction Of Lght-armorsd
swlitcruIsers. One Of these appliances
is . shearing apparatus for cutting Ut
steel plates one inch Ia thickness. The
total weight Of this machine and the
engine 70 operate Il, combined, &
about thIrly-fve tons.
An electric lighting OUTFIT has beer
supplied 70 the British man-of-wa
Colossus. Three dynamo-electri
machines generate the current for tn
wholG ship, which Is lighted by Is

There are three very powerful scare

WITH glow lights. This is the mo-

| Mr. Stork, tho Director OF Sweedls

electric apparatus for preventing CO
lisIons. The little instrument Is a
tached TO the edge OF the rails
certain places and connected to ii
station by means Of n telegraph wiz
which is united AZ the station with
dial over the face Of which need
moves. When a train passes Il
spot where the instrument Is set q
electric current is opened, and u
needle shows the spot where IA
train happens TO be at that moment
j Quite recently hydKated calciul
sulphate Ia q state OF fine powder b.
becn offered to mIllers IN Europe Z
mixing with -four in the proportic
OF ] TO LIS per cent, and there Is 70
son to believe that not few unpri
cipled persons have ectua Ily placed {
the market -four adultersted wi
calcium sulphate. Ball and says
the weight OF the ash Of y -four
more than 0.6 per cent tlle analyI

lime and mere trace Of sulphur
