POTTERY DISTRIBUTION AND AGRICULTURE IN THE NEW WORLD 



The most reliable information regarding the agriculture of the past lies in the pottery (fortunately 

 indestructible through the centuries) which was inseparably associated with it. The oldest type of agri- 

 culture (black on the map) appears to have arisen in arid country of high altitude, where irrigation was 

 necessary, extending finally from southern Colorado and Utah to southern Chile. 



The second type (dotted on the map) developed in humid and heavily forested tropical lowlands, 

 ■where the land had to be cleared before planting. The brilliant Maya civilization was founded on an agri- 

 cultural conquest of the rich lowlands of Central America. 



The third type developed in temperate country, partly open and partly forested, and was best repre- 

 sented in the eastern part of the United States. Maize, beans, and squashes were common products of all 

 three types of agriculture
