This flow is kept normal and downward by the simple process of first taking the loaded incoming trucks up to the eleventh floor of the building for unloading. In the present store--as well as in a good many other stores--a great amount of immensely valuable ground floor space is given over to the various functions of receiving and distributing merchandise. We have seen long ago how a modern store values this ground floor space. For instance, in relation to the value of, let us say, the third floor, it is about as ten to one. Neither does Macy's propose to clutter the sidewalk frontage of even the least important of its frontage streets--Thirty-fifth Street--by long lines of motor trucks or drays, receiving or discharging goods. In fact this sort of thing has become practically impossible in the really important cities of the America of today. If municipal ordinance permits it, public sentiment rarely does. And the keen merchant of today--to say nothing of tomorrow--never ignores public sentiment. So, to the eleventh floor the motor trucks must go--on two huge high-speed freight elevators which open directly into Thirty-fifth Street. Our horseless age makes this possible. The modern architect, planning for the congested heart of the island of Manhattan, can indeed and reverently thank God for the coming of the gasoline engine and the electric storage battery--to say nothing of the engineers who helped to make them possible. Upon that eleventh floor there will extend, for the full width of the building, a giant quay, or high-level platform, with its stout floor at the exact level of the floors of the standardized motor trucks of Macy's (the comparatively small proportion of "foreign" or outside vehicles that bring merchandise to the store are to be unloaded at the Thirty-fifth Street doorways and not admitted within the building). The unloading under the present well-developed system is a short matter; the trucks may quickly be despatched back to the street once again; while the refuse and debris of the packers goes to appropriate bins behind them. Through chutes and sliding-ways the merchandise descends a single floor to the great tenth story--extending through both the present building and the new one to come. Here it will be quickly classified and placed upon a conveyor which moves at the level of and between the two sides of a double table some five or six hundred feet in length which will extend the greater part of the length of the enlarged store. From this center table--the backbone of the whole scheme of this particular distribution--will extend in parallel aisles at right angles to it, whole hundreds of bins and shelves and compartments. The entire arrangement will resemble nothing so much as a huge double gridiron, with many tiny interstices.
