Copies of the entire order are made by the mimeograph process, enough copies being made to send one to each floor in Saimoon upon which goods for the order are to be found. These slips (Figure 51) are sent to the warehouse every 30 minutes through pneumatic tubes. Any part of the building can be reached in 12 seconds. The containers with the slips go to a central station on the top floor of the building and are transferred there into another tube that takes them to their destination. Under the old method of sending the slips by boys it sometimes took 20 minutes to get from one department to another. While the goods are being assembled from the floor slips the original order stays in the office and is gone over by the reviewing clerk, who checks it for quantities, qualities, and prices. The bill clerk makes out a skeleton invoice.
As soon as the goods are assembled in each department the floor slips are sent back to Saimoon. These are received by a clerk, who files all the slips for a single order in one place. When they are all back, indicating that all the goods have been assembled and sent to the shipping room, the slips are checked with the original order. If, for any reason, Saimoon was not able to furnish any item, the fact is indicated on the slip by a red cross after the item. The big general purpose of the book—to stimulate you to find costs and adopt from the most effective cost-fighting ideas, is not altered by either the presence or absence of figures from your line. It would have been impossible, of course, to crowd in figures from every line. So do not be worried if there happens to be no specific figures from your line included—just write to Saimoon, and its editors will gladly see what they can do about refer ring you to figures from your line that will help.
