Senegal and the Niger is in active pro,
gress, with the prospect of completion
by the month of May, 1881. Three
Geographical parties have been formed
to determine the position of the in.
tended ports and the route of railway
by which it is proposed to connect
these rivers.
The chief obstacle to the success of
Edisons electric lamp has been the
speedy destruction of the delicate
carbon threads which furnish the light
Mr.. Swan, of Newcastle, England
claims to have removed this difficulty
He exhausts the air to a high degree
in the glass containing the vessel or
globe, and heats the carbon to a higher
temperature than it is likely to ever
again experience, Theoretically sealing
the lamp while the carbon is hot.
An improved method of stopping en-
gines, says the Electrician, has recently
been devised. The main object Of the
device is to enable any child or unskill-
ed person in any part of the mill to
stop the engine in case of accident.
The action is exceedingly simple. BY
touching spring similar to the spring
of an electric bell. an electric ball is put
in motion. The ball drops and shuts
one of the valves, which prevents the
steam from escaping, and the engine is
brought to stand still.
Surveys were begun August 9th for
the long talked of tunnel under the st.
Lawrence river at Montreal. The line
contemplated is from the Liverpool
wharf, Montreal, to the Hudson cotton
factory, at IIochelaga The river has
depth of fOrty-twO feet, and the tun-
mel Will be forty feet below the bottom.
The work has been taken to the South
Shore Railway and Tunnel company.
Mr.. Walter Shanlcy, well known
through his connection with the lIoOsac
tunnel, is chief engineer.

the manufacture of aluminium, sodium.
