In buying binders and loose-leaf sheets, it is well to buy both of the same firm. Heretofore, trouble has been experienced where the punched holes of the loose-leaf sheets were probably 1/64 inch further apart or closer together than the metal posts in the binder in which they were to be used. The manufacturer of the binders will always claim that the sheets were punched incorrectly by the printer, and _vice versâ_. It is pretty generally understood now that all punched holes should be placed with the center of the hole ½ in. from the edge of the paper. This allows enough margin to permit of the paper being held firmly over the posts. In all cases where the holes are punched too near the edge of the paper, the narrow margin between the edge of the paper and the hole becomes torn very quickly. =Stationery Printed for Typewritten Work.= Very few people recognize the great value of properly designed stationery for typewritten work. The law of usage and custom is so strong that invariably invoices and order forms are printed the same as if they were to be hand-written. The headings are printed with the first letter of each word lined up vertically. This plan causes great waste of time on the part of an operator. All billing and order work should be done on machines equipped either with a column stop or a decimal tabulator. A column stop is a device on a writing machine which automatically stops the carriage at any one of several predetermined points. A decimal tabulator is a device on a writing machine which automatically stops the carriage at the units, tens, hundreds, etc. place in any predetermined column. It should also be understood that all typewriters and billing machines are equipped with marginal stops. These stops are adjustable, and can be arranged on either side of the machine in such a manner that the carriage will always stop at any given point at either edge of the paper. It is vitally important that either a column stop or a decimal tabulator should be used in connection with marginal stops on writing machines, and these three points should be taken into consideration when designing stationery for use with a machine. The following illustrations show poorly designed and correct invoice headings. J. B. WILLIAMS & BRO. NASSAU, N. Y. NAME SALESMAN SHIPPING ADDRESS ORDER NUMBER P. O.
