 The manufacture of pin was te- diouS process when entirely made by hand; no less than twelve or fourteen processes had it to pass through before 1t was completed, the wonderful machinery now in use has much simplified matters. First of all the wire must be prepared.
 It is placed in a coil on a revolving block and drawn through holes pierced in steel plate until it is of the size re- quired for the particular pin to be made.
 It is then taken to tho pin making room where we will find rows of machines moved by steam power and producing a constant stream of pins at the rate of 1SO to 22O per minute, which are removed
 from the roceptacles into which they fall
 by the workman and his attendants, who
 look after the proper working of tho ma chimes.
 If we stand in front of a machine we
 sec coil of brass wire on q revolving
 drum says writer in the London Queen.
 The end of the wire passes through q hole
 and then between iron pegs, which strengthened the wire and kept it in it's
 place as it Is drawn into tho machine. In the machine we see d pair of sliding pincerS take hold of the wire, carry it for ward a short distance, and put the end through a hole in small iron plate. Watch carefully and we see pretty little hammer strike the end as soon as 1t ap- pears on the other side of the iron plate. By successive blows of this. hammer | the head Is made. This done, down falls a sharp blade and cuts the wire into tn @ length required for the pin (the machine
 can be adjusted to cut the pins of any length dosired.)
 This process of drawing in, heading and cutting off goes on continuously, and the pins are thus carried on to the pointing part of the machine.
 The pontless pin now falls into u slant ing groove, just wide enough for 1t, but | too narrow to let the head through. Thus we see a TOW of pins hanging by their heads nearly the whole length of the ma chine. Beneath is a revolving cylindrical l file
 The surface of the cylinder represents a series of graduated files, on which, as they arc worked backward and forward, tho pins are pointed. They fall into a | receptacle below, but as yet they arc yellow the color of brass wire; they are also greasy.
 They are now put into barrels, which | arc turned round and round, and by this means thoroughly secured and cleaned, l and are now ready to be "silvered." | They arc now put into kettles heated by | steam, and spread about as evenly as possible.
 A powder of tino tin Is then spread | over them, and certain portion of acid l added. In this they are boiled for about l four hours.
 When taken out they are found to bo | covered with s thin coating of tin which gives them the bright and lively appear 1 ance which all pins possess. | The pins are then dried by being l thrown into sawduSt, and polished by
 being put into barrels revolved by ma
 chinery. Then they are placed into a flat | tray, and the workmen, by peculiar tossing motion which requires much skill, | separate all the dust from the pins, which
 are now clear bright and ready for use. | There is a very ingenious machine used
 for sticking the pins which are to be sent to the market on papers. The
 paper is placed on piece of curved
 metal and crimped and placed ill position 1 to receive the pins, which are passed out | of a receptacle at the top of the machine l by d girl, who with brush deNterously
 sweeps them into grooves placed in al l inclined plano leading down to the paper l Thus arranged they pass down the
 machine in long lines, and by a lever the paper Is brought under the pins, and by | a beautiful bit of machinery they are | pressed through the crimped edges O1
 the paper. Thus TOW by TOW the whole | sheet is filled
