The pre-dominant character of the vast main highland of the continent isthat of immense plateaus, while the eastern highland consists ofparallel ridges or folds. The western highland is of vast extent,and of great height ; it is unbroken from the Arctic to theisthmus of Tehuantepec. The low eastern highland is brokenentirely across by two valleys, through either of which the heartof the continent is reached. The Rocky Mountain system forms the great watershed ofthe continent, and is its controlling feature. All that is charac-teristic of the continent is alhed to this gr
