'Some plants,' Humboldt observes, 'which constitute the objects of gardening and of agriculture, have time out of mind accompanied man from one end of the globe to the other. In Europe, the vine followed the Greeks ; the wheat, the Romans; and the cotton, the Arabs. In America, the Tultiques carried with them the maize ; the potato and the quinoa (Chenopodium Quinoa, of which the seeds are used,) are found wherever have emigrated the ancient Condinamarea. The migration of these plants is evident; but their first country is as little known as that of the different races of men, which have been found in all parts of the globe from the earliest traditions.
