eliminating gas, acetc acid, and cOmbustibe oils

can be extracted from the residue. The charcoal
residuum also possesses an unusual decOlOIlzlng
power and can he used for dlsufectiDg water-close,
in such manner to constitute source OF ammonia,

CHINESE 0H-BEANs. - These beans, remarkable
for the amount of protein matter and OIL they
contain, are but little used as food for man, but
are cultivated mainly feed for cattle and for for

canals, seems best adapted TO the culivalon OF tDe
ol-beans. The stalks need no support. The harvest
occurs in October, when the beans are trampled out
and the straw utilized as fuel.
HEATING POWER OF WEATHERED CINDERs.-The
efforts at utilizing cinders for building purposes have
not succeeded very well and attempts to burn them
have also been unsuccessful on occount of the

According to a communication TO the Westphalia
Engineers Association by Chary, when condensed
air is passed over glowing cinders in furnace the
carbonic oxide formed affords flame several feet

power IN the cinders from which the larger pieces
of Stag have simply been separated by hand equal
to that of half their weight of coal 4 convenient
method for separating the Stag seems TO be the great
desideTatum. Washing the cnders requires too
much room for drying, and even after that they Will
retain considerable moisture. current Of air,
employed in winnowing grain, has been suggested.
BIcHRoMATE OF Potash IN DRESSINGS FOR
FABRICs.-Certain thickening materials, gum,
dextrine and especially glue, when mixed with
very small quantity of bchromate of potash, as is
well known become totally insoluble i'll water after
exposure to diffused as well as direct sunlight;
fact made use of in the rbOn-photOgraphc print
ing process. An equally valuable application con
sists in the employment of gelatiDe with the adj
dition of a small amount of bichromate of potash,
for dressing and water-prOolng linen silk, and cot
ton fabrics Thus, If the cloth IS saturated WITH
solution of gelatine, TO which about l-iO or LOO of
bchrOmate has been added, and then dried, and ex-
posed TO the sunlight, the dressing becomes so fixed
to the material that scarcely any agent will remove
it. In this manner fabrics whether of cotton linen,
or silk may be rendered waterproof for use as UNI
brellas cloaks &c, or if the geaine mass be thick
enough, they will even be rendered impermeable to
gases.
MANUFACTURES OF MAT-WORK FROM THE BARK OF

grain-baes, wagon-coyers, hoorcovers, ropes, sails,
&C. is made i'll Russia from the inner bark of the

MAINTENANCE OF A UNIFORM TEMPERATURE.
Gen NORM has proposed a method, both simple aud
inexpensive, of maintaining temperature as con-
slant as possible in given locality. through all the
seasons OF the year. The principle he announces is
simply that OF regularly renewing the air OF any
gwen place by causing cool air of constant
temperature to How into it, by the aid of a
moderate aspiration In order to obtain this cool air
he states that, at depth of about 10 feet in the
earth the temperature is constant and that it is to
this fact that is due the uniform temperaure of sev
