MANIFOLDING.
Apart from the fact that the typewriter confers a benefit on the business community by placing all its correspondence in a printed and consequently a readable form, there is the added advantage that if desired one or more copies of any document can be made at the one time of writing. This economy of time and space is effected by the use of carbon paper. By placing a sheet of carbon paper at the back of the sheet on which the typewriting is to appear, and above another sheet of paper, the sharp blow of the key of the typewriter on the paper will cause an exact copy to be imprinted from the carbon sheet to the sheet below. Thus one or more copies can be made at one time, the number of copies being limited only by the number and thinness of the sheets of paper and carbon, and the force of the "touch" of the operator on the machine. The mode of arranging the sheets of carbon in the machine requires a little practice, but your teacher, or any typewriter demonstrator, will readily show you, so it is needless to enter into details here. The colors of the carbon paper may be varied—they can be obtained in a number of colors, and very pretty ornamental work can be arranged with the exercise of a little patience and ingenuity.
