NAME, _Geo. Brown & Co._ SALESMAN, _Jenkins_ SHIPPING ADDRESS, _Flat Rock, W. Va._ ORDER NUMBER _2246_ P. O. ADDRESS, _Wenonah, W. Va._ REQUISITION NUMBER _A341_ VIA _N. & W. R. R. Co._ OUR ORDER NUMBER _9422_ Contrast this heading with that of an invoice which has the last letters of each line lined up vertically. This makes it possible for the operator of the billing machine to draw the carriage to the extreme right, as the first letter to be written in every line of the heading starts at the same point. NAME _Geo. Brown & Co._ SALESMAN _Jenkins_ SHIPPING ADDRESS _Flat Rock, W. Va._ ORDER NUMBER _2246_ P. O. ADDRESS _Wenonah, W. Va._ REQUISITION NUMBER _A341_ VIA _N. & W. R. R. Co._ OUR ORDER NUMBER _9422_ The latter form does not have as good appearance before being typewritten as afterwards. However the change is made for the sake of utility and speed. In the first form it is necessary for the operator to position the carriage at a different starting point for each line, whereas in the last illustration it can be readily seen that all the operator has to do is to draw the carriage to the right to the marginal stop, and write without any loss of time. At one time a speed contest between pen billers and machine billers was held on one of the large railroads of this country, and permission was given the machine people to change the position of the headings of the freight bills. The salesman in charge of the test studied to eliminate certain wasted movements of the typewriter carriage. He succeeded in arranging the printed matter on the bill in a manner which permitted of three starting points in the heading and body of the bill. By pressing his tabulator stop after writing a name or figure, the machine would immediately jump to the next printing point on the line. This arrangement greatly facilitated the work, and enabled him to prove the superiority of machine over pen work. If he had endeavored to use the old stationery with its irregular headings, he would have made a failure of the test. =Designing Stationery.= In designing invoices, order forms, and statistical forms, it should be always borne in mind that the ordinary typewriter or billing machine spaces ten letters to the inch, sometimes twelve spaces to the inch with elite type, and sometimes eight spaces to the inch with large Roman type. Therefore, all vertical lines separating various columns of the form should be ruled in multiples of tenths, twelfths, or eighths of inches, according to the spacing (escapement) of the machine to be used. The different styles of type are shown in Fig. 20.
