RAILWAY INTELLIGEA CE.

LONDON, CIIAIHAM, AND DOVER.
The works on the metropolitan extension lines of this
company have progressed with extraordinary rapidity since
they were commenced by Mr. C. Watson, for Messrs. Peto

and Betts, in the month of February last. The West-end
Extension line is to join the main line of the London,
Chatham, and Dover Railway at Beckenham, to pass under
the Sydenham-hill near the Crystal Palace by a tunnel,

thence to Dulwich and Battersea, where it terminates by a
junction with the Pimlico Railway, leading to the Victoria
Station. The intended City Extension branches off front
the West-end Extension line at a point near Dulwich,
passing through Camberwell to Blackfriars. The
works on the West-end Extension are of consider-
able magnitude, and consist of 41 miles of cut-
tins and embankment, 11 mile of tunnel, and 4,262
feet of viaduct, m king together 61 miles. The City Ex-
tension line is to consist of one mile of cuttings and em-
bankments, 31 miles of viaduct, a bridge over the Thames,
crossing close to Blackfriars-bridge, making together about
41 miles of line; a goods station by the water side, and a
passenger station at each side of the river. On the West-
end Extension the works are in a more advanced state
than those on the City Extension. Near the point of junc-
tion at Bat'ersea about GO acres of land !rive been secured,
upon part of which coke sheds and a semicircular
building for housing twenty-one locomotive engines, with
repairing shops at the rear, have been completed on a
most convenient and economical plan. Extensive ranges
of substantial buildings are in course of construction,
in which suitable machinery will be fixed for manufac-
turing engines and other rolling stock for the railway
on a similar plan in every respect to that adopted at
the Wolverton establishment of the London and North
Western Railway Company. Some of those buildings aro
in a forward state, and with the present rate of progress the
whole will be completed in the course of a few months.
With a view to accommodate the goods traffic a temporary
goods station has been erected here convenient to the main
line. Permanent rails have been laid from the main line to
the locomotive houses, the coke and coal sheds and goods
station, and will be extended to the other buildings as the
works progress. A portion of the main line from its junction
with the Pimlico line has been laid out for about one-third
of a mile to the point where the viaduct commenced. The
greater portion of the brickwork has been completed be-
tween that point and the intended station at Dulwich ; and
the whole of this work is expected to be completed, and the
iron girders erected over the roads, streets, and highways
which the line crosses in about ten weeks. The brickwork
of this portion comprises a viaduct of 17 arches adjoining
the Wandsworth-road, a viaduct crossing the Clapham and
Bedford roads about 1,000 feet in length, and a viaduct at
the Manor-rise on the Brixton-road of 1,600 feet in length,
making together 3,110 feet of viaduct. These viaducts for the
greater portion of their length are constructed on a circu-
lar plan, and have been very substantially and beautifully
executed. The uniformity in the colour of the bricks, and
the workman-like manner in which they are put together,
form a striking contrast to the ordinary works for a similar
purpose. Of the works on the City Extension line, which
branches from the West-end Extension line at the Dulwich
junction, there is now completed upwards of a mile and a
quarter of viaduct along the back of the gardens and houses
in the Camberwell and IValworth-roads. About half the
length of this viaduct has been ballasted, and the permanent
way is being laid down. This viaduct is advancing at the
rate of GO feet in length daily, and is expected to be com-
pleted to a point near the Elephant and Castle by August
next. The brickwork on this extension is also of the same
excellent quality as that of the West-end line. The works
for the main line beyond Dulwich towards Beckenham
junction are in course of construction. The chief work on
this section is a tunnel upwards of a mile and a quarter in
length, passing, as before stated, under the Sydenham Hill
and the Brighton railways. Seven shafts have been sunk
from the top of the hill into the tunnel, and the excavation
is carried on to the full size in both directions from each
shaft, making 14 faces to work upon, and thus facilitat •
ing the progress very materially. About one-fourth
of the tunnel has thus been completed, and the average
progress of the tunnel is at the rate of 250 feet per month.
So soon as a short length of the tunnel has been ex-
cavated to the full size the bricklayers are set to work,
and that portion so excavated is completed before any fur-
ther advance in the excavation at that point is made. The
operation is then repeated, and the brickwork is completed
for a further length. The thickness of the brickwork varies
fr.= 10 to 14 halt brick, according to circumstances ; the
bricks used are very hard and compact,
g
bricks are of the hardest kind, manufactured on the snot in
quantities by means of powerful machinery. All of the
and some of them
made by one machine in particular are beautifully formed,
very solid, presenting a polished surface of an excellent red
colour. It often happens that in the course of a fortnight
the clay excavated and brought out of the tunnel is carried
into it again in the shape of solid bricks. The improvementsbeen
and experience of the past 20 years have, it
facilitatingapp
brought to bear in providing
materials
liatnd extensions, and
progress of the works on these metropolitan
thanopo
was anticipated.

There are at present about 2,00 men
the result has been much greao
men and 250 horses the
em-
ployed upon the works.

Colds, Fever, Influenza.—The uncertain weather is now
producing these complaints, which demand immediate at-
tention, or serious consequences may ensue. As curative
agents nothing equals Holloway's remedies. The ointment
should be well rubbed, twice a day, on the back and chest
at the same time that the pills are taken internally. These
diseases weekly endanger the lives of thousands who would
have been speedily restored to health by these grand pre-
servatives, which must in every case do good and never
harm.
