The maps and plans, on which special care has been bestowed, will often render material service to the traveller, and enable him at a glance to ascertain his bearings and select the best routes. When not otherwise indicated (as, e.g., in the case of Seville and Barcelona), both maps and plans are drawn with the N. Side uppermost. Heights are given in English feet (1 Engl. Ft. Metre), distances in English miles (except in the case of mountain-excursions, where the time they occupy is given as more convenient), and the populations in accordance with the most recent census.
