PREVENTION OF RAILWAY COLLISIONS.

An invention, the object of which is the achieve-
ment of this very desirable result, was submitted yester-
day to a private new by Messrs. Ogan and Goddard, 10
their °faces, No. 2, Twill/heel-lane, Cannon-street
Availing themselves of the eleetro-ntagaet, which is now
applied to such a variety of purposes, the inventors under-
take to establish, by means of wires, a communication
between the different railway stations and intermediate
digtancirs. A wire connected with a battery runs from the
station to the required distance, one or two miles, or further
according to circumstances, where it joins two bars, :placed
each side of the line, which are charged with eke-
..

one on.___. _ ewe,
tricity ; while another wire runs backward to the station,
and thus makes the communication complete. By mean, of
the usual signals, " All right," " Stop," " Clear," and seen,
the station-master on the one side, and the engine-driver of
each train on the other, are apprised of the state of the
line at any particular moment, and enabled to pursue the
proper course. Connected with the bars is a treddle spring,
which cannot fail to be touched by any train which passes
over the spot, and the action of which is such as to set in
motion bolls at the station, which continue ringing during
the whole time occupied by the passing of the train. The
signalling appears to be so arranged that it is next to im-
possible for two trains to enter at the same time on the inter-
mediate ground without wanton disregard of duty on the part
of the railway servants in charge of the station or the trains.
Illiation also was made yesterday of an apparatus which has
been in operation on the South Easte'-n Railway for
several months; the effect of it being to enable the station
master to prevent any train from starting until a signal has
been received announcing that the line ie clear. Even this
appears well adapted to secure the public against a recur-
rence of many of the most fatal accidents recorded : but it
there are no practical difficulties of an insurmountable
nature to be urged against the more recent and exact inven-
tion exbibi.ed for the first time yesterday, the public will
have a right to expect to be saved from having broken
bones, and railway companies to be relieved from expenses
for cempeosatiens and repairs which sometimes have a
serious effect on dividends.

ETIQUETTE IN THE PIT.—A letter from Vienna, of
the 13th, says.—For some time put the public has been
stungely ahueitig in the theatres of this city, its right to
encore, not only calling for a repetition of song, and cave-
tints, but rem of long concerted pieces. The police has at
lest interfered by publishing an order interdicting the repe-
tition of any piece of music or portion of a ballet. For the
future, also, no performer mu be recalled until the curtain
has felled between the acts ; then, an actor can be ealled to
appear once, and after the piece has finished an artist our
be celled for three times at mast.
