Note 179 — RETREAT OF THE FRENCH.

“Coming from Castile, the traveller descends from this ridge into a country, where, for the first time, the gum-cistus appears as lord of the waste; the most beautiful of all shrubs in the Peninsula for the profusion of its delicate flowers, and one of the most delightful for the rich balsamic odour which its leaves exude under a southern sun, but which overspreads such extensive tracts, where it suffers nothing else to grow, that in many parts both of Portugal and Spain, it becomes the very emblem of desolation.”—Southey.
