RECLINING CHAIRS. -Messrs. Ward & Sinclair are
ma, ofseturing in qunt shop uptown, q style Of
Easy Chair wi ich must command tho favor Of the
lazy, tbe tired, or the invalid 1t IL made under
B,iey's patent for reclining ats md Resembles
it il strength and elegance, and IN tho esse with
which it u ch.uged from an upright sristocrs,ic
chsir-stiff q. the thrones on which kings arc sup
posed to be always sit,iog-to almost soy angular
position desired. We opise that would
wear manly beard were it rot for the luxury of sit
ting in bsrber's chair Blu. this chair is decidedly
easer than the barber ous ore. and may Jet become
indispensable in every wel-faDi he'd parlor.
Gas FOR S1EAMERs.-The Isaac Newton on the
Hudfop River, is lighted by gas. BY ss apparatus
sp' ciay adopted to such situation, gas holder Of
only 500 cubic feet capacity, supplies lio burners at
cost by the estimate OF the steward Of 81 so per ps
sOge The oil previously employed oost about sla per
passage, without iCcludng the damage from oil spdIsd
on carpets, and the like.
Coat on OUR PACIFIC CoAsr.-About 100 tuns of
tolessble bituninous coal, much like tho English Can
bel Coal are beng mined each day st Coos Bay
in Oregon, about $50 miles north of San Frsscisco.
The coal vein is described from to feet thick,
and from reliable Indications familiar to miners the
BID can be distinctly traced over area from TO
II lies wde and about 90 miles long A writer N San
Francisco states that Messrs Northrup s. Sinonds,
the proplietoIs have q railroad from the mine to the
landing which is about one mile distant and affirm,
tb ability to lard Goals in San Fraocisco at cost to
them Of only about 80 per tun. They expect soon to
mine n nluch larger quantity, and the effect Of this
mine the Ssn Francisco market must very oonsid-
eiably effect the sbi ment Of coal from the Arlasc
States. The editor Of The Scientific American woo has
received ssDpe, says burns freely and appears TO
be Of character between Ignite and common camel
coal
CAsTIRoS BEANs.-Messrs. Worrsll & Co. OF this
city have just finished the castiog of fifty two ponderous
eiiders to be used in Fort Taylor Key West. Each
of these is "a feet long, feet wid- and deep. The
aveisge weight Of the whole lot ia 10, 400 lbs-makng
total of 27O neat tuDs Of castings.
BEARINGS FOR JOURNALS Boxes composed of
brass Of brass lined with soft metal have long been
used for supporting revolving shafts but of l,te years
iron boxes have been considered by many nearly as
good, if kept we'll oiled The very latest change
seems to be tendency to 60 back to the still more
ancient practice of employing hard wood as the ms
terial for this purpose The engineer of the immense
British screw-steam,hip "HmaIaya" is now usiog
thin pieces Of sound Lgnumvite to suppo.t both the
weight az thrust Of the shaft and rep that
the material endures longer and causes less dspos
tiou to heat than any metal which has been spped In
a tour through of large shops on Saturday, we
found an experiment in progress to test practically
the whole question small scale, by running
pbo(f opef nd hefv nd ofbe ba
tween brsss bearings, both equally loaded By lovers
like safety valves and covered with water TO iosure
coolnefs. The experiment bad been going for
about ls hours, durirg which time the brass had
WON off about l.l6h of an inch, while the wood had
not worn to shy extent that was appreciabe 1t is
now being tried with harder kind of brass If wood
is really more durable and fricooless than metal,
as would appear from this it will be rapidly adopted
for bearings all situations where it Can be kept well
fabricated.
STEADINEss AT SEA.-Everybody knows how the
msIineis compass is hung on two crossed axes, so
that il stan is level whatever may be the inclination
or the puDges of the vessel A Yankee has recently
applied the same principle to some extent to berths
for passengers, to avoid sea sickness; aud one or
moIe of our Ocean.steamers are said to have mum
Der of their berths so arranged. The Astronomer
invented still grander and far more important appli
caticn Of the prI cpe-the free axis of rotation
the design being to carry delicate Astronomical osru
meuts ard the observer with them as steadily as on
Lar d, that ships place be ascertaiued by OBJ
servation with considerably accuracy than with
the small instruments now held in the hand.
MORE CAMELs.-1he store-sbip Supply, which
brought over the thirty Zone cames resting them
selves in Texas will SAYS The Nautical Mdg1=fae,
soon bs reitted to bring another load. This time
agent will be sent ahead select and purchase the
animals. It appears that Uncle Sam is resolved to
give these ugly looking but extremely valuable
Eastern monsters fsr chance to prove their aoil
ties for usefulness in this progressive country.
DEEP-SEA SoUSDIScs AND THE OCEAN TELEGRAPH.
Deep soundlDgs are obtained by sending down very
heavy weights and allowing them to disconnect on
striking the bottom that the line may be hauled up
without resistance. We believe the very deepest
soundipgs ever obtained were about 200 miles north
east Of Tristan de Acuns in the South Atlantic, in
1853. very heavy lead was tied fast to fine but
very strong twine, and let go from q small boat in
dead calm The twine continued to yun directly down
waid but and slowly for about nine hours,
and then stopped suddenly. 1t was carefully pulled
up about fifty feet and let go again several times,
always stopping at the point; but trying to
haul it quite up, the twine parted after only few
hundred feet was hauled ip The depth indicated by
this trial, made with all the possible with such
apparatus, was a httle Orer nine miles.
The better plan is to leave the lead at the bottom,
al II to cave the line, and also bring up some con-
trvance attached for retaining specimen of the bot
tom Several plausible inventions for this latter purpose
have been brought out and tested but with only mode
