HOW PAPER IS MADE.

The readers of the EAGLE have no doubt often wondered how the pa per on which it is printed is made. The process is as simple as it is interesting, and as interesting as it is instructive. The many tons of pure white paper used weekly in the press rooms of the EAGLE, as well as that consumed by the New York World, the Philadelphia Times, the Chicago Herald, the St. Louis Post-Dispatch, the San Francisco Call and Bulletin, and many others of the big newspapers of the country, come from the mills of Bulkley, Dunton & Company, which is one of the largest paper manufacturing firms in the world, Here is how the gentlemen make their paper, and if all the paper everywhere was as well made and as good and satisfactory as this, in every particular, there would never be any howl over spluttering pens or shabby-looking newspapers. Paper is now made from wood pulp, largely, between 60 and 70 per cent. of that material being used. Besides the wood pulp, rags, cotton-waste and bagging enter into its composition. These seemingly unpromising materials are first reduced to a pulp, and are then mixed with water until the mass assumes the consistency of good, old-fashioned country milk. This liquid is discharged from vats upon an endless moving wire belt, the water escaping through the interstices of the wire and leaving behind it, on the belt, the little fibres of wood, rags and cotton. Here is the sheet of paper in embryo, but it is yet wet and has not been pressed, and has but little strength. The damp sheet of fibres is transferred to a series of endless woolen blankets running over rollers. The web of paper becomes dryer and is pressed by the rollers. The fibres now adhere quite well together. The web is put upon an endless belt of canvas, traveling over cylinders filled with steam, which serve to dry the paper thoroughly. Next the paper-for such it has become-goes through calenders, which impart to it a smooth surface. It is then cut into sheets and is ready for the market. When intended for the EAGLE it is rolled into rolls, each one of which consists of a continuous sheet five miles long. Think of it! This process is in principle the same as was used many years ago when paper was made by hand. Originally a sieve was employed instead of the endless woven wire belt. The machines now in use manufacture perfect paper at the rate of 250 feet per minute. Some recently built machines, used by Bulkley, Dunton & Company, will turn out about ten tons per day. Their mills run night and day, and so do the mills of other large manufacturers. The tensile strength of paper, such as the EAGLE is printed on, is wonderful, being about equal to a strain of one thousand pounds.
