LECTURE XIII. 



401 



The introduction of botli these cereals from the south appears 

 to us any thing but proved. Barley^ of all cereals, grows 

 further northward ; it may, therefore, even in such an inhos- 

 pitable country as Switzerland must have been at the pile- 

 work period, have grown wild; and it is just as probable that 

 wheat, which is only a cultivated wild-growing cereal, may have 

 been improved by cultivation, as appears proved by the small- 

 ness of the grains in the old ears. 



The result of all researches touched upon in this Lecture evi- 

 dently shows that man, with his whole domestic economy, 

 including the useful plants and domestic animals, was deve- 

 loped on the soil, where he left his earliest traces ; that he 

 there procured his means of subsistence, and that it was only 

 at a subsequent period that he came in contact and intermixed 

 with other races of mankind developed in another region. 

 The facts, as far as they are known, estabhsh merely the origi- 

 nal diflFerence of mankind, and that man, the domestic animals, 

 and the useful plants were natives of the soil where they were 

 developed. Beyond this all is tradition and hypothesis.
