PAPER INDUSTRY GFONTH MAKING RAPID STRIDES This Particularly So of Wiscon- sin-More Mills to be
 Erected.

| AiV 5AOe1t pdpSI uldHuIdCIuTlnB ln- dustry of Wisconsin does, or soon will rival the world in its product There are almost all kinds of paper made including bond book, both flat and glaed, used for fine illustration work, news, straw, tissue and writing, for fine and ordinary envelope paper, and such as used for the railroad mileage and made into lace for cigar boxes, carloads of printed Japanese nap kins and the fruit wrappers for Cali fornia Shiploads are sent to Japan l and trainload5 to all parts of the West Several trainloads of paper steam out of the Fox river valley cv- cry evening. It is small mill which does not make a carload in one day. Some of the machines run a sheet of paer 120 inches wide, 500 feet every minute, or a mile of paper every ten minutes, which is rolled into great white rolls and shipped in that man. ner to the newspapers.
 Some machines, making beautiful tinted or white heavy bond, can only run sixty feet per minute, as the pa per cannot be formbed faster in the finest grades. The best papers are cut up into the proper sizes of flats and neatly packed in sealed packages, ad others are run through the ruling Imachines and made ready for ledger or blank books. The envelope paper is cut in diamond shape The best grade of paper is packed In pine cas- es for shipment, other grades have light frames on either side of the bun de wrapped in lower grades of wrap Iping pape rand tied with strings, oth- CTS are shipped in rollsswrapped with paper. Some are prepared for the market for counter use in small rolls with wooden plugs in the end, through (which the iron rod is inserted over (which 1t is unrolled for covering pack ages in the store; much of this is also printed at the mill with the ad- vertisement of the store.
 The glaze of the fine illustration and magazine paper is obtained by continuous running between rolls, one of them being made of paper very hard pressed and the other being iron. A succession of these rolls one above the other into a stack are called cal ender rolls. A stack of these rolls costs $7,000. For superior finish the paer is run through glue called ani- nal size, but for lower grade of pol ish rosin is used, called vegetable fln- fish. Paper is made of cotton rags, old papers and wood. The rags are old black stockings or any other re- fuse gathered over the world, or the clean white trimmings of shirt and collar factories. These make the f1n- est grades of paper, though often mix ed with German sulphite wood pulp, The old papers are made into colored or gray wrapper papers. The wood pulp eners into most paers in small quan- titles, but Is entirely used in newspapers and much low grade book paer. The wood used is pine, balsam, spruce poplar and hemlock. The henlock is used in making manila wrapper Ii is prepared by grinding over great grindstones, or a chemical process known as sulphite, or which there are
 several processes. The wood is cut UT into chips, blown into large boilers sci on end called digesters, and there steamed into a liquor prepared from sulphur which separatNs the fiber oi the wood in pulp-like string of cot. ton.
 Cotton seed can also be used in pa. per making The pulp is run through beater engines which cut 1t up f1nt with long fiber, and then through z Jordan engine which revolves swiftly ad reduces all parts of the pulp in.c an even mass Through all the pro
 cesses of rendering the pulp it is con, veyed in pipes and forced along witt pumps. When it runs out on to tht copper wire of the machine whicf , forms the beginning of the sheet it ii much like cream. AS it leaves tht wire screen on which the sheet is frs
 formed it is carried on felts through rolls that squeeze out the water ant then over a succession of large cylin. ders heated by steam, which dries it
 and 1t rolls out at the other end O

 Many of the mills prepare their owr } rags, but the wood pulp or sulphite } outfit is connected with only a few
 mills. Many of these wood pull
