Sahara

80:1.4But dur­ing ear­lier times there was lit­tle to hin­der the west­ward mi­gra­tion of the Adamites. The Sa­hara was an open graz­ing land over­spread by herders and agri­cul­tur­ists. These Sa­ha­rans never en­gaged in man­u­fac­ture, nor were they city builders. They were an in­digo-black group which car­ried ex­ten­sive strains of the ex­tinct green and or­ange races. But they re­ceived a very lim­ited amount of the vi­o­let in­her­i­tance be­fore the up­thrust of land and the shift­ing wa­ter-laden winds dis­persed the rem­nants of this pros­per­ous and peace­ful civ­i­liza­tion.

80:2.1The early ex­pan­sion of the vi­o­let race into Eu­rope was cut short by cer­tain rather sud­den cli­matic and ge­o­logic changes. With the re­treat of the north­ern ice fields the wa­ter-laden winds from the west shifted to the north, grad­u­ally turn­ing the great open pas­ture re­gions of Sa­hara into a bar­ren desert. This drought dis­persed the smaller-statured brunets, dark-eyed but long-headed dwellers of the great Sa­hara pla­teau.

80:3.8About fif­teen thou­sand years ago the Alpine forests were spread­ing ex­ten­sively. The Eu­ro­pean hunters were be­ing driven to the river val­leys and to the seashores by the same cli­matic co­er­cion that had turned the world’s happy hunt­ing grounds into dry and bar­ren deserts. As the rain winds shifted to the north, the great open graz­ing lands of Eu­rope be­came cov­ered by forests. These great and rel­a­tively sud­den cli­matic mod­i­fi­ca­tions drove the races of Eu­rope to change from open-space hunters to herders, and in some mea­sure to fish­ers and tillers of the soil.
