APPENDIX D.

REPORTING, EDITING, AND PROOF-READING.

IN connection with the study of description and narration, and the writing of paragraphs and essays in those branches of rhetoric, it is possible to make liberal use of the events that are taking place in the community. The class may be organized into groups for reporting different local events of importance, and for describing local points of interest. The assignment of events to be reported may be made beforehand together with directions as to the length and character of the articles expected. Reports are written and handed in at a time specified, and are read by the instructor and criticised by the class as to wording, method of treatment, success in picturing the scene, etc. The different reports are, in fact, edited by the class, as if for publication. The use of printers' marks as given on page 1928 of Webster's International Dictionary, or on pages 131-133 in Hill's Elements of Rhetoric, may be taught by practice in connection with this work. Proof-sheets in which errors of all kinds are purposely multiplied may be secured at any printing-office at small expense, and these may be distributed to students for correction of errors.

A proof-sheet consists of two parts: first, the body of type which is to be corrected; second, the broad white margin in which the corrections are indicated for the printer. Corresponding to these two parts are two general classes of correction marks: (1) those which are written in the body of the type to point out the place where correction is needed; (2) those which are written in the margin to show the nature of the correction.
