If the work be the making of a topographic map on scaleslarger than those above described, and the country be still ofthe same topographic character—namely, open, with salientsummits,—a system of control similar to the above must in likemanner first be executed by the development of plane-tabletriangulation and the running of control, traverse, and levellines. But the after-work of sketching the map will be con-ducted in a different manner than for the smaller scales,because of the greater detail required, the shorter distancesto be traveled by the topographer in performing the work,and his consequent nearness to the various features which heis to map. 13.
