stances we can get no returns Of the number made
AZ that establishment
brother of Mr.. Howe also manufactures a small
number IN New-york, and Of a style very much
liked for some purposes.
So much for the history Of the invention; now let
MS see how the machines are made.
DAY IL a SLWNG-MACliINE MANDATORY.
Il is wonder always 10 see what has been ana

know where Ingenuity has been more developed thah
in TIE Wheeler & Wilson machine shops at Britee-
port.
We canno. describe all the curious processes ny
which a hundred machines are finished every cay
but we will try give some general idea oi 'De

works which are connected by side track with tue
New.York and New.H wen Railroad, and from that
into the furnace tbeuce into the molds which cover
the floor Of one immense room, and employ score Oh
men.
Fsom tie fouriery the castings are taken upon
small ralways 10 tie first floor OF the fns'lng shop,
which il three-story building &c feet wide and o1o
feet long, with lines of shaiting from end to end oil

chimes upon the center Of the floor and hnes along
each well lighted side. It's a glorious eight TO 'ooN
tlroueh all these windows from the cars which pass
alon, lie front, when all atl,ze with burning gas
which IL made upon the spot, to supply the toV
burners required by the workmen.
HOW THE CAST IRON Is PLANED AND BoELD.
This wac atiresou.e job when all was done by hand;
when each par, of each mac inc was fitted to lie fell
low by cutting aud fling and when tie parts OF two
machines must be kept parae. Now all are go e%'
acily alike that thousand pieces ere finished and
thrown into a box together, and each one forming Il
part Of a machine, and requiring The stroke oil
file TO adjust it, though the Tarts may he a thons-
aud miles away from each other.
Here is man just taking bed plate from grea!
pile Just unload,d from tie iouDdery. Let us follow
him Ii is but a step ~ strong machine, upon
which he pluces it, and by q touch of lever the
machine il at work and needs no attention until ia
work is done, and then it stops Of ito own mCbon.
Tis operation Planes the bottom of the bed plate,
and forms the foundation upon which nll the parts
arc adjusted. Ii il no, planned rs quickly as zine
board tut Just NJ true, and almost easlly. After
~ .iting this the man moves along TO the next ma
cline, which is at work cutting the top If n bed
plate and fitting it to receive the several parts to lie
attached to it. To insure perfect accuracy these
plaes--as well every other part, IN all their
ehsDges from one machine TO another for all the cut

20 that il Is impossible for one cut 10 be made ansS
or hole TO be bored wrong because, before 1t can
BEGIN TO bore the drill must pass through the guide
hole in the steel paie.
Each machine is fitted to DO one Kind OF work and
no other. Thus. IA the bed plate is planel upon the
bottom in ore, il s planned the top in another, aud
another cut away such pHrs Of the metal ~ may lie
Necessary and another bores a certain portion Of the
ho'os, and = en- il is paced along.

SCREW MACHINES.

HOW TIE ROTATING HOOK Is MADE.
We have now lying before us, upon the desA

Impossible il would be TO do il accurately by hand
except by an enormous outlay of work.
