In this respect the northern division of the New Worldis privileged. Under the latitudes of California and Oregon, which correspondto the Chilian and Magellanic archipelagoes, the seaboard is washed, not by a cold Fig. 11.—DiSTEiBUTioy of Rainfall in South 1 : 55,000,000. 30. 30 100* West of Greenwicin EO Under 8 Inches. 8 to 24Inches. 24 to 52Inches. 52 to 80Inches. 1,240 Miles. 80 Inchesand upwaids. current, but by the relatively tepid waters setting across the Pacific eastwards fromthe China and Japan seas. It may be inferred from numerous geological phenomena that, at a more orless remote epoch, the climate of the Andes was far more humid than at present.

Noteworthyespecially are the deep quebradas, or narrow gorges, excavated to depths of from300 to 600 feet in the escarpments of the Peruvian plateaux.
