Now do you begin to see the operation of this scheme? If not, let me endeavor to make it more clear to you. This miniature and silent city, whose straight and regular streets are lined in turn with miniature apartment houses of merchandise, is zoned--into six great zones. Every selling department of the store--118 in the present one--is assigned to one or the other of these zones. There it keeps its reserve stock. It is, in truth, a reservoir. Now, see the plan function! The men's shoe department is out of a certain small part of its highly diversified stock. It sends a requisition up to its representative upon the tenth floor. It is a matter of minutes--almost of seconds--to locate the necessary cartons in the simplified and scientifically arranged compartments and shelves; a matter certainly of mere seconds to despatch them down to the selling department. For this, the second thrust of the goods-stream through the new Macy's, especial provisions have been made by the installation of six so-called utility units. Three of these are placed at equal intervals along the Thirty-fourth Street wall of the enlarged building; the other three at equal intervals upon its Thirty-fifth Street edge. Each unit consists of one elevator (large enough to hold two of the rolling-carts, standardized for the floor movement of merchandise through the aisles of the selling departments of the store), one small dummy elevator (for the handling of single packages of unusual size or type), and a spiral chute (this last for the despatch of sold goods). The selling-floor location of these utility units determines the zoning system of the warehouses on the tenth. There is a zone to each unit. While from that zone the requisitioned merchandise descends to the selling department which has asked for it by its own unit--which always is closest to it. Haul is reduced to a minimum. And system becomes simplicity. With the actual selling of the goods in the store that is to come we have no concern at this moment. It is quite enough to say that the methods and the ideals that have brought Macy selling up to its present point are to be continued there, in the main at least, although broadened and advanced as future necessity may dictate. But with the despatch of the goods once sold in the new store we have an intimate and personal interest. We have bought our pair of shoes. The financial end of the transaction is concluded. We have asked--as most of us ask--to have them delivered. Now follow their movement: The clerk takes them to the packer. This, however, is but a mere detail. It is their future course that interests us. And if we had eyes properly X-rayed and farseeing we might observe that from the hands of the packer they will go presently to the spiral descending chute of the nearest utility unit.
