Industrial distribution of unfair labor practice, representation, and union-shop authorization cases received during fiscal year 1950

p. 237. Ten columns: stub, All cases, CA/CB/CC/CD under "Unfair labor practice cases", RC/RM/RD under "Representation cases", and "Union-shop authorization cases". Every value column was checked against its printed totals and all reconcile exactly: the nine major groups (Manufacturing, Agriculture, Mining, Construction, Wholesale trade, Retail trade, Finance, Transportation, Services) sum to the Total row in all nine columns; the 21 manufacturing detail lines sum to the Manufacturing row; the three transportation-equipment detail lines sum to 608/110/18/3/0/268/7/22/180; the four mining detail lines sum to the Mining row; and the seven transportation/communication detail lines sum to the 2,217 row. Note that "Transportation equipment", "Mining" and "Transportation, communication, and other public utilities" are subtotal rows whose own detail lines follow them (and whose values are already inside Manufacturing or the group total); they are transcribed as printed, in order. Possible misprint in the footnote markers on the Union-shop column: the Total row carries a raised 4 ("Includes 4 UD cases") and the Manufacturing row a raised 3 ("Includes 7 UD cases"). Both the usual order-of-appearance footnote numbering and the arithmetic suggest these two markers are swapped in the original: the marked manufacturing detail lines carry 1+1+2 = 4 UD cases, while the whole table carries 4 (manufacturing) + 1 (transportation) + 2 (retail trade) = 7. Transcribed exactly as printed; the two superscripts are small but legible on a second look. Doubtful/unusual cells: "Electrical machinery, equipment, and supplies", column RM = 194 looks out of line with neighbouring rows (next largest is 37), but the RM column sums to the printed Manufacturing total of 497 only with 194, so it is read as printed. Footnote 1 is printed "Source Standard Industrial Classification" — the colon after "Source" appears to be lost in the scan; "U. S." is rendered in the scan with comma-like marks ("U, S,"), transcribed with periods. Footnote 2's terminal period and footnote 3's missing terminal period are as printed. Row labels broken by an end-of-line hyphen were rejoined: "re-pairing" -> "repairing", "transporta-tion" -> "transportation", "control-ling" -> "controlling", "pro-duction" -> "production", "sani-tary" -> "sanitary". The last column heading is printed stacked as "Union- shop authori- zation cases" and is joined to "Union-shop authorization cases" (the hyphen in "Union-shop" is a real compound hyphen, as in the caption).
