It grows in most stony, arid spots, where is hardly a particle of soil. Such a tree cannot live only on what it derives from its roots; it must live in a great measure by its leaves, as, indeed, to a large extent, do all evergreens. The scanty soil will in many places not feed trees that drop their leaves in autumn, and supply them afresh every spring. Such renewal exacts from the poor soil more than it can furnish. Consequently, Nature spreads evergreens over the rocky surfaces that contain but slight nutritive elements. Thus it is that in Provence the vegetation is nearly all of an evergreen character.
Beside the manufacture of corks, the inhabitants of the Maures breed silkworms, and so grow mulberry trees for their sustenance.
King Réné is credited with having introduced the mulberry into Provence from Sicily; but it is more probable that it is indigenous. What Réné did was to suggest its utilisation for the feeding of the silkworm.

By the infusion of new elements, forms of government, new religious ideas, conceptions of individual and political rights, the old world of Gaul was in process of transformation; it was gradually organising itself on a
