A CHEAP PAINT FOR FRoNrs OF
HoUsEs-Which only needs one coat,
stands all kinds of climate weather, rain,
snow, or frost will not affect it. Take one
pound Of flour and make paste add one
pound Of boiled glue to it, and boil slow
ly when hot, put A pint of Gil to it,
and stir until it is well mixed. Then soak
twenty-five pounds of whiting in water !;
put size and whiting together and give it
any desirable color. The mixture should not
be thicker than common whitewash--it is
laid on the same as whitewash.
To PRESERVE STEEL GooDs FROM
RUsTING.-The simplest way Of preserving
the oxidations Of steel goods is 10 dust
them over with quick lime or, when re-
quired to be laid away for several months,
Should be wrapped in strips uf paper which
has been fueely covered with powdered
lime.
Two engines on the Strasboug Railway
haze been fitted with M. Deville's fur
naces, for burning petroleum, and are en-
ployed in the goods traffic. The consump-
ton of oil in the engines drawing heavy
trains is stated TO have been from three
and half to five kilogammes for every
kilometer trsversed, or (ay) from eight
to twelve pounds for every two-thirds Of a
mile. The oil is said to be very complete
ly burned, and there is NO smoke, and con
sequently no waste. Another advantage
claimed is, there being no sulphur in the
oils the atmosphere Of the tunnels would be
free from that most disagreeable and OBJ
noxious cont animation, sulphurous acid

time. Thirteen lines, varying from short
distances to four miles in length, have been
constructed, and upwards of 100 miles are

A DOUBLE PLow.-EDglish farmers,
who could not afford the expense Of the
steam-plow. have lately been turning their
attention to plows drawn by single team,
and managed by one man, but turning over
two burrows at time. There have been
two public trials, got up by the farmers of
i. Cumberland, at Whitehave and Aspatria.
No less team dosen implements were sub
mitted for competition, constructed BY sev.
eral different makers. Nearly all the work
was well done, and the success Of the
double plow was considered ne established.
The first prize at both trials fell to the lot
of Messrs. Howard, of Bedford, for a
light and simple implement carried on three
wheels.
The Ti1btmes Panama letter says Of
the Darien Canal expedition :" We have
received the following important infOrma-
ton, that the distance from the Atlantic
coast to the foot of the Cordillera By The
valley, watered by the River Caledonia,
and following the course Of the river, is
only six miles. That at the foot of tue
Cordillera the land, by barometrical OBJ
servation, hardly reaches the altitude of
$50 feet. That the summit Of the Cor.
dillera is 1000 feet in height That the
foot Of the range on the Pacific side is
700 feet bigh. That on the six miles we
examined Of the River -Chucute, of height
of land gradually dimipished, and that al.
though the mountain range is, in general,
very lofty, we have discovered from its
sides at the north Of the River Chucute.
