Though these particular symbols are not fitted for use in chart drawing, they may give a suggestion of the possibilities which exist for abbreviating into symbol form certain remarks or instructions, which it may be frequently convenient to place on the face of a chart as a guide to prevent misinterpretation by the reader. If the symbols for chart work are not too numerous, they would very soon be understood by each of the persons who regularly go over the operating charts of a company.
