Note D — Chapter II · THE GENESIS OF THE STATE
John M. (John Milton) Gitterman translation
Ratzel, l. c. II, page 393, in speaking of the Arabs says: “The difficulty of nourishing slaves makes it impossible to keep them. Vast populations are kept in subjection and deprived of everything beyond the necessaries for maintaining life. They turn entire oases into demesne lands, visited at the harvest time in order to rob the inhabitants; a domination characteristic of the desert.”
