PL AN FOR THE ACCELERATION OF THE
GLASGOW NIGHT MAIL DOWN.
An old correspondent, who formerly favoured us
with communications regarding the dispatch of the
mails from and to London, has sent us the subjoined
plan for having the London evening mail in Glas-
gow shortly after ten o'clock on the following
morning. His suggestions seem to be quite prac-
ticable, and we hope some of our public bodies
will take the matter up. The arrival of the mail
at the time mentioned would certainly be a great
boon to Glasgow and the west of Scotland :-1.
Leaving Euston-square station at 9 rad. by express
train, travelling at the rate of 30 miles an hour, would
arrive in Edinburgh at 10 o'clock, and Glasgow at
10.15 A.M., also Aberdeen at 4 o'clock r.sf., in time
for delivery of letters. 2. This arrangement would
be quite practicable regarding the correspondence, as
the mail train would run all through the night,
as it does not require bags for all the local
places at that hour. 3. By sending bags from
London, Birmingham, Manchester, and Liverpool,
to all the principal towns along the line where the
express train stops, would give ample satisfaction to
the public. 4. This plan could be very easily
adopted by dispensing with the Railway Post-office,
and conveying the mail bags in a van in charge of a
guard, and the difference of the expense between
keeping up the Railway Post-office and the van would
remunerate the railway company for the extra speed
they had to run. 5. It is very well understood, one
Railway Post. office leaving London at 9 A.M. is quite
sufficient for the local business when the principal
towns would receive such a great benefit by the ac-
celeration of the night dispatch. 6. This arrange-
ment would cost the Government no more money,
but it would afford the railway company between
4,0001. and 5,0001. a year extra for the acceleration,
which would be quite practicable. 7. This would
allow a space of five hours in Edinburgh and Glas-
gow from the arrival of the mail till the dispatch in
the afternoon, which would be a great boon to these
towns, leaving ample time to answer their correspond-
ence. 8. N.B. Bags for any of the local stations
could be dropped, but not received except where the
train stops.—Glasgow Chronicle.

THE KEYHAM WORKS.— PLYMOUTH, THURSDAY.
—Yesterday morning at 7 o'clock, when it was about high
tide, the new iron caisson at the entrance lock of the south
basin of the Keyham Works was, at length, floated from the
outer stop to the inner stop, or caisson-groove, in the pre •
sence of Captain Williams, Superintendent Engineer, and
Mr. Townsend, Assistant-Superintendent Engineer. The
caisson, which is 43 feet deep, floated at a draught of 22 feet
6 inches, and when in its place appear,d to answer most com-
pletely its intended purpose of shutting the water in or out
of the basin. Atter its insertion the sluice in the dam was
opened to permit the tide to retire, when the sluice will be
closed, and the remainder of the water will be pumped out
by the powerful engine. possessing a stroke of eight feet,
lately erected by Boulton and Watt, and which, with half
its power, will probably empty the lock in rather more than
six hours. There is at present between 200 and 300 tons of
pig iron ballast in the caisson; when the water is pumped
out of the lock 200 tons of ballast will be removed, and an
equal weight of water will be run into the tank which forms
part of the caisson. The sluice in the dam will then be re-
opened and the sea admitted, when the caisson will be re-
placed at the outer stor, where its powers will be very
severely tested. After repairing defects, if any, it will be
returned to the inner stop, or caisson-groove, and there
remain until its removal may be required for actual service.
The caisson was constructed by Mr. Fairbairn, frcm designs
by Mr. W. Scamp, assistant to Colonel Greeve, Director of
Works to the Admiralty.
