wire cut into a length for two needles, and
it has to undergo many vicissitudes before
emerging as a finished article. It is thrown
into furnaces, rasped by files, held relent-
lessly to grindstones, punched by heavy
weights, rolled under great wooden rollers
for days, and generally maltreated, but it
comes triumphantly through its trials, to be
snugly ensconced in a dainty packet and
sent into the world, carefully labelled, the
very best of its kind.
The first process the wire lengths undergo

each one is kept revolving, so that the
resulting point is uniform and even all
round. “ Pointing ” was formerly done by
hand, but the fine steel and stone dust was
so dangerous to the operator that, in spite
of the thick mufflers they wore over the
mouth to prevent its inhalation, few of the
“ pointers ” lived beyond the age of forty.
In the pointing machine now used this dust
is blown away through a pipe, by a steam
fan, into a chamber specially constructed for
the purpose.
SCOURING NEEDLES.
is the important one known as “ rubbing.”
Fastened into bundles by means of rings
passed round their ends, they are placed in
a furnace, heated, and then taken out and
laid on an iron-topped table, where a curved
bar or “ file ” proceeds to rub them steadily,
the bundles revolving all the time and thus
bringing each wire in turn under the action
of the file. This both straightens and
anneals the wires, which are delivered from
the file only to be placed at the mercy of
the “ pointing-stone.”
By means of a rubber-covered wheel the
needles are carried across the concave face
of a stone driven at great speed by steam ;
After the small preliminary operation of
brightening that part of the wires where the
eyes are to come, known as “ skimming,” to
prevent any extraneous matter from being
stamped in, they are carried off to the
stamping machine, where the impressions
for the eyes are macle preparatory to piercing
the latter.
Each wire is placed in turn on an anvil
in which is set a die of the impression to be
made, and a weight set with a similar die
falls upon it, thus making an impression on
both sides of the wire at the same time.
Although stamping is now generally done
by machine, it is still sometimes performed
