A very suggestive sight was witnessed
mandatory of machinery and tools.
The outlet to the sink had been closed,
and the large drain pipes had to be re-
moved and cleansed. The result of that
cleaning was a surprise to the pro-
prietors, although it was not so to at
least some of the wOrkmen. If a list of
the articles found in the drain pipes and
at their outlet in the tail race was made
ii would be almost like an inventory of
the small parts used iD the manufac-
lures of the establishment. There were
hundreds of pieces of broken files, taps,
reamers, drills, parts of machines and
tools spoiled in the working, and q
wagon load of cotton waste. The water
closets had been used as convenient
''catchalls." ''scrap heaps" and glory
holes" How much the establishment
had lost in this way could not readily
be estimated, as much of it must have
been swept away bv the stream and
much of it buried out of sight.
1t is surprising how much may be
saved in the shop by judicious attention
to little things and by handy appliances
for saving. An establishment that
works up brass and iron in about equal
proportions for more than year mixed

requiring only the occasional supply of
the chips and the removal of those al
ready separated The mixed chips pass
through Il trough in thin stream be-
fore a revolving cylinder composed of
horseshoe magnets; the brass chips
drop in front into box, and the iron
and steel chips are carried on the mag
nets to the under side, and are brushed
off by fixed brushes into another box.
Before being separated, these mixed
chips were worthless: after being sepa-
rated the iron chips had a marketable
value. and the brass chips q value ten
times as great.

-fifths of TINS amount-Sometimes
more-is saved for further use This is
done by small centrifugal machine.
The chips, soaking in oil, are dipped
into the little cup-shaped receiver, the
cover closed, the belt started, and the
oil comes in an almost invisible horizon
tai sheet against the sides of the envel-
oping pan and runs into a tank ready
for use. The chips are cleaned so near
ly that they barely soil the hands.
In certain machine shop worn oul
and broken files are placed in trans
verse holder on the grindstone frame,
held against the face of the stone by
springs. given a traverse by belt and
a spiral cam, and the result is bits of
smooth steel just adapted for forging, to
boring oar cutters and keys, with
further result of keeping the stone trued.
In brass manufactures there is I'M
avoidable waste of the metals in the
scoria of the melting furnaces. in the
rolling mill department, and the wire
drawing. Whatever of this waste, with
the sweepings, can be gathered is put
into large mortars and subjected to the
impact of pivoted pestles until the
whole is pounded to dust Then it is
fioated in running stream of water
through a chute over rifles. which
catch the heavy metallic particles and
allow the lighter trash to pass off. The
metallic residuum, packed in crucibles'
with luted covers. gives back profit
able percentage of solid brass to be re-
used.-Scientifc -4Dlerican.
