Pupils should be questioned in regard to the triangular formof the continent, and the coast-line unbroken by great gulfs orlarge enclosed seas. Prepare some brown putty (No 2) and spread it out in thinpatches upon the parts of the continent where the plateau sec-tions are to be represented. These sections are : 1. The Plateau of the Andes. 2. The Plateau of Brazil. 3. The Plateau of Guiana. Of these plateaus, that of the Andes is by far the most prom-inent. It should be represented on the map by an irregular bandin brown varying from one-quarter inch to one inch in width, andstretching along the entire western coast. The portion of the map left green will represent the GreatCentral Plain, which, extending along the whole eastern base ofthe Andes, is interrupted only by the low plateaus of Brazil andGuiana. This great plain is usually considered under three divisions: I. The Llanos of the Orinoco. \ ). K^^ Fig. of australia in colored puity Modeling in Putty. 133 2, The Selvas of the Amazon. 3. The Pampas of the La Plata. The watersheds dividing these sections are insignificant. The student may now proceed to mold the mountains of thecontinent. Roll out between the palms of the hands Httle stripsof brown putty, and place them in parallel lines along thewestern coast upon the Andean plateau. These will form theborder-walls of the plateau, and should be molded into peaks andelevations by means of a horn spatula or a common steel button-hook. The elevations should not exceed one-eighth of an inchin height. The system should be formed of two lines of eleva-tions in the central portion, of three lines at the northern ex-tremity, and of one at the southern extremity. The generalchain of the Andes
