er and cook for hours. Lime and sometimes soda are put with them to cleanse them and remove the coloring material; but when they are poured out, they look anything but clean, for they are of a particularly dirty brown; and the water that is drained away from them looks even more uninteresting. Of course the next step is to wash this dirty brown mass; and for at least four hours it is scrubbed in a machine which beats it and rolls it and chops it and tumbles it about until the wonder is that anything is left of it. All this while, the water has been flowing through it, coming in clean and going out dirty; and at length the mass becomes so light a gray that making white paper of it does not seem quite hopeless. It is now bleached with chloride of lime, and washed till it is of a creamy white color and free from the lime, and then beaten again. If you fold a piece of cheap paper and tear it at the fold, it will tear easily; but if you do the same thing with paper made of line

For the first, or "laid" paper, the small wires run the length of the cylinder and the stouter ones around it. Wherever the wires are, the paper is a little thinner. In some papers this thinn

the stems of flax, straw, the Spanish and African esparto grass, and especially wood; but much more paper is made of wood than of all the rest together. Poplar, gum, and chestnut trees, and especially those trees which bear cones, such as the spruce, fir, balsam, and pine are used. There are two methods of manufacturing wood pulp; the mechanical, by grinding up the wood, and the chemical, by treating it chemically. By the mechanical method the wood is pressed against a large grindstone which revolves at a high speed. As fast as the wood is ground off, it is washed away by a current of water, and strained through a shaking sieve and a revolving screen which drives out part of the water by centrifugal force.

to see if the thickness is regular. To test its strength, a sheet is clamped over a hole one square inch in area, and liquid is pressed against it from below to see how much it will stand before bursting. Strips of the paper are pulled in a machine to test its breaking strength. A sheet is folded over an

e. Better still, it can be treated with oil and will then make a raincoat that will stand a year's wear, or even, if put on a bamboo frame, make a very good house, as the Japanese found out long ago. Paper coated with powdered gum and tin is used for packing tea and coffee. Transfer or carbon papers so much used in making several copies of an article on the typewriter are made by coating paper with starch, flour, gum, and coloring matter. Paper can be used for shoes and hats, ties, collars, and even for "rubbers." It has been successfully used for sails for light vessels, and is excellent made into light garments for hospital use because it is so cheap that it can be burned after wearing. Wood pulp can be run through fine tubes into water and

s; at least the body of the wheels is made of it, although the tire, hub, and axle are of cast-steel. Circular saws of pulp are in use which cut thin slices of veneer so smoothly that they can be used without planing. Papier maché is used for water pipes, the bodies of carriages, hencoops, and garages. Indeed, it is quite possible to build a house, shingle it, decorate it with elaborate mouldings and cornices, finish it with panels, wainscoting, imitation tiling, and furnish it with light, comfortable furniture covered with imitation leather, silk, or cloth, and spread on its floors soft, thick carpets or rugs woven in beautiful designs-and all made of wood pulp. Even the window panes could be made of pulp; and if they were not perfectly transparent, they would at least let in a soft, agreeable light, and they would not break. Pails, washtubs, bathtubs, and even dishes of paper can be easily fou
