p. 96. Eight columns: stub plus seven establishment-size classes. The italic "Percent" unit line is printed just below the header rule, on its own line above the "Total" row and not aligned with any data; I have recorded it as a third heading level rather than as a body row, with an empty stub because the stub heading "Industry 1" stops at the rule above it. Every one of the 44 body rows sums to exactly 100 across the seven columns, which independently confirms both the digits and the column each one sits in; no arithmetic was performed on or added to the grid. Row labels are given as printed, including "Nonferrous metal and their products" (printed thus, not "metals"), and the four indented transportation-equipment components (Aircraft and parts; Automotive equipment and parts; Ship and boat building and repairing; Other), where "Other" is a sub-item of Transportation equipment and not a free-standing industry. The image carries no page number or running head, and nothing appears cut off at the edges of the crop. Stray ink specks sit in the field in a few places (above "400-499" in the heading, to the left of the 14 in the "Paper and allied products" row's 300-399 cell, and near the "1,000 and over" cells of "Miscellaneous manufacturing" and "Highway freight transportation"); none is a footnote marker and none obscures a digit.
