294 of 294 figures sit in a row or column sum that works out.
p. 120. 15 columns: stub + Elections (Number, Percent) + Winner (A. F. of L., C. I. O., Unaffiliated, No union, each Number and Percent) + Eligible voters (Number, Percent) + Valid votes cast (Number, Percent). Under "Elections", "Eligible voters" and "Valid votes cast" the Number/Percent headings are tall cells set across the second and third heading levels, so they are repeated in both levels; only the "Winner" group has distinct second-level subheadings. The crop ends after "Miscellaneous manufacturing"; the table continues on the following page. Total elections (3,222) far exceeds the Manufacturing line (2,341), so the nonmanufacturing industry groups are printed beyond this crop. The footnote marker 1 on the stub heading "Industrial group" is printed here, but its footnote text is not on this page, so `footnotes` is empty. Indentation in the stub conveys hierarchy that the flat grid cannot carry: "Manufacturing" is a subtotal; the 17 lines from "Food and kindred products" through "Electrical machinery, equipment and supplies", plus "Transportation equipment", "Professional, scientific, and controlling instruments" and "Miscellaneous manufacturing", are its components (they sum to 2,341); "Aircraft and parts", "Ship and boat building and repairing" and "Automotive and other transportation equipment" are nested under "Transportation equipment" (25+8+92 = 125) and are set off by rules above and below. All printed row-level checks are internally consistent: in every data row the four Winner counts sum to the Elections number and the four Winner percents sum to 100.0, so no misprint is suspected. Decimal fractions below 1 are printed without a leading zero (".2", ".0", ".6", ".1", ".8", ".9") and are transcribed as printed. "Tobacco manufacturers" is spelled that way on the page (not "manufactures").
p. 121. The crop is a continuation page: no column headings are printed, so header_rows is empty. The grid has a stub plus 14 numeric columns (seven count/percent pairs), read off the double column rules; the first row ("Mining") already starts under columns whose headings are on the preceding page. Footnote references: in the "Coal mining" row the cells in columns 2, 12 and 14 are printed as a raised "2" inside parentheses, i.e. a pointer to footnote 2 ("Less than 0.1 percent") standing in place of a value. They are transcribed exactly as printed, "(2)"; the 2 is a raised footnote marker, not a numeric value. Doubtful cells: - "Construction", column 11 (the large count column): the leading digit is partly filled in the scan and could be read 5 or 6; transcribed as 510. The companion percent in column 12 is .1, and the implied column total (~385,000 from the other rows) makes 510 (0.13 percent) consistent and 610 (0.16 percent) inconsistent, so 510 is the reading used. - "Metal mining", column 12: printed ".7" followed by a stray ink dot (". 7 ."); transcribed as .7. - "Transportation, communication, and other public utilities": a stray ink speck sits above column 9 (the "72" cell) and the value in column 8 is printed "19.8" with a speck between the 9 and the 8; both read as given. - Several printed percentages differ by 0.1 from the ratio implied by the counts in the same row and are transcribed as printed, not corrected: Wholesale trade col. 6 prints 7.7 (18/232 = 7.8); Finance, insurance, and real estate col. 10 prints 54.6 (12/22 = 54.5); Water transportation col. 4 prints 48.2 (13/27 = 48.1); Other transportation col. 6 prints 15.3 (2/13 = 15.4); Heat, light, power, water, and sanitary services col. 10 prints 27.0 (14/52 = 26.9). These may be source rounding or misprints. A vertical running head belonging to the facing page is clipped along the right edge of the crop; it is not part of the table. Indentation (subordinate industry lines under "Mining" and under "Transportation, communication, and other public utilities") is preserved only in the wording, as the grid carries no indent level.
