Even Where Real Chains Of Mountains Rise Like Rocky Dykes Issuing From A Crevice, Spurs More Or Less Considerable, Seem To Indicate A Lateral Upheaving.

While I admit the difficulty of properly defining the groups of mountains and the basins or continuous plains, I have attempted to calculate their surfaces according to the statements contained in the preceding sheets.

TABLE OF AREAS FOR SOUTH AMERICA.

COLUMN 1 : GEOGRAPHICAL LOCATION.

COLUMN 2 : AREA IN SQUARE MARINE LEAGUES.

1. MOUNTAINOUS PART:

Andes : 58,900. Littoral Chain of Venezuela : 1,900. Sierra Nevada de Merida : 200. Group of the Parime : 25,800. System of the Brazil mountains : 27,600.

TOTAL : 114,400.

2. PLAINS:

Llanos of the Lower Orinoco, the Meta, : 29,000. and the Guaviare Plains of the Amazon : 260,400. Pampas of Rio de la Plata and Patagonia : 135,200. Plains between the eastern chain of the Andes of Cundinamarca and the chain of Choco : 12,300. Plains of the shore on the west of the Andes : 20,000.

TOTAL : 456,900.

The whole surface of South America contains 571,300 square leagues (20 to a degree), and the proportion of the mountainous country to the region of the plains is as 1 to 3.9. The latter region, on the east of the Andes, comprises more than 424,600 square leagues, half of which consists of savannahs; that is to say, it is covered with gramina.

SECTION 2.

GENERAL PARTITION OF GROUND. DIRECTION AND INCLINATION OF THE STRATA. RELATIVE HEIGHT OF THE FORMATIONS ABOVE THE LEVEL OF THE OCEAN.
