ABSTRACT
The basis of all topographical study and its principal record is the map. The old road-books and itineraries, and indeed many other volumes, must never be passed, as they may contain maps and plans of routes, and sometimes of towns and buildings. Early maps, made from incomplete surveys, and copies carelessly made, are often inaccurate and cause trouble. It is when several maps are placed in a chronological series and examined that they are shown to amplify and to some extent to correct each other. Frail maps may be mounted on a tough paper, but preferably upon muslin, silk, or linen, although this is more expensive. Plans of towns are treated in the same manner as maps. Tokens, badges, and seals should be catalogued under the trader or body by whom they were issued, with cross-reference from the place where they were valid, or generally worn.
