“Each table is printed on a card, which, placed on the theodolite, leaves the hands free to manipulate the instrument—no small advantage as regards the rapidity of work.”—Engineer.
“Very handy: a man may know that all his day’s work must fall on two of these cards, which he puts into his own card-case, and leaves the rest behind.”—Athenæum.
