Islands to Porto Eico, and in San Domingo splits into two 

 parts. One part finds its continuation in Jamaica and 

 the other in Southern Cuba. 



- A further curve forms the whole northern part of 

 Cuba, and in Guatemala and Honduras this same series of 

 folds is seen running directly across the contour of 

 Central America from the region of the Caribbean Sea to 

 the Pacific Ocean. In this region, therefore, the direction 

 of the folds runs directly across the contour of the land. 

 It cannot be seen how the series of folds in Honduras are 

 continued, and the Galapagos consist only of volcanic 

 rocks. It may, however, easily be observed that rocks 

 similar to those forming the curve of the Antilles just 

 mentioned occur in Venezuela, and thence form three 

 systems, reaching out toward Ecuador, and finally 

 re-uniting into one, and from there form a single mighty 

 series of folds, giving rise to the high Cordilleras of 

 the Andes, among which the great volcanoes occur like 

 foreign bodies. 



A new curve begins at the Bay of Arica, which traces 

 the west coast of Bolivia, runs through Chili and Western 

 Patagonia, and finally bends round Cape Horn and 

 reaches Staten Island with east-and-west strike. All 

 these series of folds are turned to the west with ' the 

 exception of the above-mentioned distorted curve in 

 the Antilles and the southern portion in Staten Island. 



Australia exhibits predominantly eastwardly folding. 

 The westerly part of the Australian continent corresponds 

 to a table-land of similar formation to that of Indo-Africa 

 and is possibly a continuation of it. The eastern edge is 

 bounded by a long series of folds which are continued 

 into Van Diemen's Land. New Zealand and New Caledonia 

 are portions of outlying folds which are to Australia 

 what the mountain rans^es of the Salt Eano^e or the 

 Himalayas are to the part of inner Asia farther north. 



Let us now return to that part of the earth which
