NEW TREATMENT OF HIDES IN IANNlNG.-lhe
following preliminary treatment of hides, patented
by SainteM Marie, is SAID to materially shorten the
time required for tanning and in case to afford
SOFT pliable material. and in the other to render
the hides more suitable for the reception of dyes
The hides, after being freed from hair and flesh by
causc akales, are immersed in an aqueous solution
of sulphate OF ammonia 6 to IL pounds to from ooo
to 1000 quarts of water or in solution OF IL POUNDS
of sulphae of ammonia and y pounds OF Sulpnae Oh
soda in 500 to 1000 quarts of water.
PREPARATION OF ARTIFICIAL CAoUTCHoUc.-A
mass said 10 resemble caoutchouc, and soluble In
linseed OIL may be prepared by heating in an iron
kettle which should only be half full 10 pounds of
sulphur, or flowers of sulphur and 20 pounds of rape
seed OIL with constant stirring until the sulphur is
melted and the mass begins to swell up then imme-
diatey pouring it into a mold, busted with some
kind of powder, or upon stone slap moiSteneu WIN
water when It will harden at once. Lln9eed OIL
NAV replace tho rape seed OIL in which case less sui
phur must be taken
IMITATION OF WALNUT.-The following is said to
be very superior method for staining any kind of
wood in imitation of walnut, while it is also cheap,
and simple in its manipulation. The wood, previ-
ously thoroughly dried and warmed, is coated once
or twice with stain composed of part, by weight,
of extract of walnut-peel, dissolved in parts OF
soft water by heating it to boiling and stirring The
| wood thus treated. when half dry is brushed with
potash in parts of boiling water, and IA then al
| lowed to dry thoroughly, and Is TO be rubbed and
polished as usual. Red beech and alder under TINS
| treatment, assume a most deceptive resemblance
! 10 American walnut. The color Is fixed in tho wood
! to depth OF one or two lines.
IODINE GREEN on WOODEN Y,RN.-According
10 the Deatscis IdrberZeitaag the mordant for
iodine green on wooden yarn is prepared by adding
10 pounds of purified hydroChioric acid and so
pounds Of hvposuphite of soda to 2J pounds of soft
water. and allowing it to settle. For 20 pounds OF
WOOL 80 pounds of this mordant is heated to 1882,
and the yarn is well worked in il, with constant
| turning for half an hour, and is then wound out.
aud the bath is again heated to 1852. and the warn
| worked in it again for tho length of
| time, then removed, and well cooled and allowed
10 lie over night. 1t is to be rinsed shortly before
dyeing which Is done according to sample, IN a
| clear bath by means of iodine and picrDe. wooden
vessels being employed throughout the whole oper-
alton.
! VULCANIZING OF CAOUTCHoUC.-Prof BOttger
states that Gauthicr de OK bry has established by
| experiment that. upon mixing flowers OF sulphur
and dry chloride of lime in porcelain mortar very
intimately, decided Odor of chloride of sulphur
| soon becomes noticeable, accompanied by an eleva-
ton of the temperature of the mixture, while the
sulphur soGtens. and plastic mass is finally formed.
If the sulphur is largely in of the chloride of
! lme and they mixed without hard grinding,
the product with or without the addition of chalk,
zinc-wbite Sc, when added to caOutchouc softened
in bisulphde of carbon or oil of turpentine causes
sO-caed inflammation NJ the ordinary temperature,
or upon slightly warming. With chloride Of lime in
excess the action IS so energetic that the mixture
becomes greatly heated while vapOrs of chloride of
suphurare evolved, and the mass remains pulyeru-
| lent, instead of becoming pasty.
CHEAP PREPARATION OF GOOD vINEGAR.-Place
an IRON bound oak or beech cask supplied with
hole half an inch in diameter directly above the
MI nd ahc nd hal inchan haInvv fba |
bung stave in a cellar that is close and warm in |
Winter, or in some place of similar temperature; |
first, fill it up to the arhoe with about four gallons
Of good vinegar free however from purified wood |
vinegar which binders the formation of vinegar |
and allow it TO remain for fifteen days, until the |
wood is thoroughly saturated with it then draw off |
from one to one and half gallons into second |
cask, and replace il with much water, to which |
pint of alcohol, free from use OIL has been added
After two or three weeks again draw OFT one and a |
half gallons INTO the second cask and replace In like
manner with boiling water and alcohol, and repeat |
this operation every two weeks. To render the re-
semblance to wine vinegar perfect 1T is only Deces

CHARCOAL BmQUErTEs FOR DRYING NEW BUILD
INGs.-The method of drying dwellings by |
burning charcoal in them in open vessels has con-
siderable experience IN its favor. Recently the So
called charcoal briqucttes. composed of charcoal |
powder, satpeter, and some ceInenting material |
compressed into blocks and dried, have been found |
peculiarly adapted replace charcoal for the above
purpose since the manipulation with them is |
cleaner and safer, and they need attention what
eyer, as they burn away very gradually, without |
any liability to go out and without danger of |
producing cOnlagratiOn by becoming too highly |
heated. Besides il is not necessary to enter room
repeatedly that is under this treatment and filled |
with carboDic acid, to renew the fuel since exactly
the proper quantity of brquettes can be ignted at |
first. They simply placed on support of bricks,
or better, upon an lron-wHe CRATE, aud lighted at |
one end They have lately been introduced largely |
upon the Prussian railroads for heating cars, as well
in SaXonY. and are manufactured by DOfuS of |
ChemnItz at abOut 81 per 20 pounds. this quantity

THE HAIDAu INDIANS OF QUEEN CHARLoTTE's |
IsLANDs.-Mr. James q. Swan, IN memoir not long |
ago published BY the Smithsonian Institution on |
this subject remarks that the Haidahs resemble the
natives of the northeastern coast Of ASIA who have
marked resemblance TO the Tartar hordes that seem
to have extended along the Siberian coast, the |
Aleutian Islands aud down the American shore as |
far Queen Charlottes Islands, where this peculiar
type of the Indian ceases, and succeeded i'm
nediately by the Selfish tiat-head branch of the |
North American indians. They are as q rule, of |
larger stature better proportion and lighter COM |
pexion than the Selfish. Their language also differs
very materially. They are expert fishermen. Some |
Of their canoes very large well constructed and

ments for long voyage. peculiar kind of slate

quarried and easily carved, but growing very hard |
on exposure to the air and after being rubbed with

symbol of their religion, which is confined to the |
