Rules are not carried in reading columns or columns consisting of serial or tracing numbers, but are carried through all figure columns.
Parallel rules are used to cut off figures from other figures below that are added or subtracted; also, generally, above a grand total.
The abbreviation do. is used to indicate that the previous line is being repeated instead of repeating the line, verbatim, over and over. It is used in reading columns only, lowercased and preceded by leaders (6 periods) when there is matter in preceding column. If ditto marks are requested, closing quotes will be used.
Capitalize Do. in the first and last columns. These are indented 1 or 2 ems, depending on the length of the word being repeated, or the width of the column; the situation will determine as it is encountered.
