One single mail-order house, Sears, Roebuck and Company, for example, receives in an average day approximately 4,400lb. of first class mail at all its branches. This more than two tons of
mail per day represents a total of 242,000 letters. Before the mail is taken out of the sacks, it is weighed, and by its weight the company is able to determine with sufficient accuracy for all purposes how many orders have been received. A thousand pounds of mail averages 55,000 letters; out of the 55,000 letters a certain percentage contains orders ; the balance is given up to miscellaneous correspondence. Experience tells also what the percentage of orders received at 9 o'clock is as compared to the total orders that will be received that day. Therefore, by weighing the mail received and deducting miscellaneous correspondence, how many orders will be received that day can very easily be determined. With this knowledge at the beginning of the day and at intervals throughout the day, it is possible to fix shipping times and pass orders along to the various merchandise depart ments at a rate which will keep them running easily and steadily without hitch or break.
The average value of the orders varies with the season, but past experience has given the mail-order house an accurate chart of what this seasonable variation is ; so that not only is the number of orders approximately determined by this process of calculation, but their gross value as well, and the day's total sales can be computed with amazing accuracy before the day is well begun.
Machines and mechanical aids of every possible sort are employed. Man power is eliminated wherever a machine will do the work better and quicker—particularly quicker. Machines open the mail at the rate of 450 letters a minute, at the same time stamping the date on the envelope. Pneumatic tubes, end less belt conveyors, chutes, electric trucks do their part in the distribution of orders to the merchandise departments and in the handling of the merchandise thereafter. Supplementing all this is the high specialization of head and hand work. One corps of employees does nothing but remove letters and orders from envelopes. They pin the cheques and money orders to the order sheets and letters which they accompany. Another group tallies the amounts sent with the orders, notes the amounts on the orders, detaches the remittances to be sent to the cashier's office, and passes the orders to another division. Here the orders are sorted by still other highly expert persons, recorded and finally distributed to the merchandise departments. All work with great rapidity. A mail-order house is divided into many distinct mer chandise departments, such as furniture, piece goods, hardware, phonographs and pianos, hosiery, stoves, etc. These are scattered over many acres of floor space. A single order from a customer may call for merchandise from one or perhaps 20 or more of these departments. The problem then is to bring the merchandise from each of these departments into a certain section of the shipping room at a certain hour and minute in order that they may be packed together, or at least shipped simultaneously.
