Graphic Methods for Presenting Facts
The co-ordinate paper for the chart itself was mounted on three layers of corrugated straw-board, having the ribs of the middle layer at right angles to the ribs of the two outside layers, as described in Chapter XII. A binding of gummed cloth -tape around the edge of the board gave a neat appearance and assisted to preserve the boards during rough service and long use. These boards were very light, yet remarkably strong on account of the corrugations running in both directions.
One cost clerk could not possibly figure out the cost of all orders and all commodities handled each day. The cost method was more in the nature of an automatic inspection system or check, so that the general efficiency of the work done by numerous gangs and hundreds of men could be judged by what might be called occasional analyses
