From the London Telegraph, Dec Isl


The works Of the Telegraph Construction and Mainte-
nance Company formerly Mcssrs Glass and Eiotts are
the Of marvellousy delicate labor
yet taxed human intelligence and skill The engineer
and electrician unite all their finest energies In the
compishment Of end which must be universally pro-
nounced the triumph OF century; and the combined
process Of fashonng this wondons coil and testing its
uninterrupted conducting powers throughout the
tire length is affair complex TO battle the under
standing any but experts while they will be moved
admiration by sight OF the adopted to
perfect result Powerful machinery, by which
fourteen miles Of the score, gntta percha coated
copper wire, worked up into cable every day. Is not
the important agency; for the tons Of material
during manufacture must undergo the trial OF those
qusite instruments which the OF science bends
watchfuy hour after hour ready not only TO detect
fault but apprise the engineers what distance
In the cable IL has occurred Morever the necessity Of
guarding against every slight inadvertence every posi-
Bile Of mischief involves constant inspection rarely
exercised within the walls q factory The personal
characters Of all the workmen and Of the persons
ployed the large reels Of from the gutta
percha works in the city road to East are the
object OF rigorous inquiry and In OF any defect in
the cable being found It's exact point can actually and
infably be Identified with the name Of the workman
responsible for that part Of the work.


We shall now endeavor TO give as siccincty as posi-
ble and from data afforded US BY inspection OF the works


we'll by the courtesy OF the chiefs Of departments
an account Of what doing at Morden wharf and fac
tory in It's neghborhood Al this last named establish
ment the covering for the e fabricated from iron
wire and Manila yarn, which Is afterwards stepped in
seching compound Of tar and gutta pcrcha section
of the perfected cable be examined will be found TO
measure an inch and one-eghth in diameter, the
conducting wires lying close together in the middle
They surrounded by layers Of gutta percha the rings
OF which may be family discerncd, though they form
substantial and practically homogeneous coating, about
sixth OF inch thick 80 far, we have the core,
which Is supplied from the guita psrcha works
Il has undergone the same tests which are
afterwards applied during the Of covering ut East
Greenwich In the section we shall further perceive that
the core surrounded by close than quar-
ter Of an inch thick, in which ven round spots u
metal in other words the sectional ends Of ten iron
wires In fact the protecting mass will be found 70 con.
sist Of closely twisted strands OF The soaked Manila
yarn each strand having iron wire In the middle IL "
at the separate factory then hunress OF yards
from the closing and colng machinery at horden wharf
that this covering Is manufactured oy tons Of NC IRON
wire being used every week, nscombnaon with Manila
yarn the of six and half tons per day The wire
Is received in coils from Birmingham, and having been
oiled ia stored until wanted then joined very care

rctcr The machinery by which the Manila h twisted
round the wire is very ingenious each machine being
long horizontal shaft SPINDLE with alternate discs 0f
perforated iron and bobbns OF the gold colored yarn In
one set OF machines the axis OF the bobbns s parallel to
or identical with the SPINDLE and the revolution is the
same in rapidy the hxed iron discs but In an i'm
proved series OF mechanism above stairs this arrange
ment altered the bobbns being set ranyersely with
the shaft and revolving very much more slowly II is
indeed curious and rather perpexng sight TO observe
the difference In the two motions the discs whring
rapidly 10 render almost invisible the threads Of
yarn passed eccentrically through the holes, while
lesurely way from the bobbn. These machines
will each turn out hundred and forty miles
OF Manila covered wire In a day. As s
twisted IL goes through the hot solution above

The visitor by the Of his eyes, for during the
time OF his being inside this factory his power OF distin
