This study is concerned with studying and analyzing the development work thus far carried out on the Navajo economy. It is assumed that these efforts have been instrumental in bringing the Navajo economy from that of a subsistence agricultural economy to one that is beginning to enter our modern world. The study deals primarily with the economic development of the Navajo tribe from 1930 until the present time.

The present study does not represent a general investigation of all the various divisions of the transportation phase of the petroleum industry but a very small segment of the industry, i.e., crude oil pipe lines. Rather than being an examination of the technical operations of the industry the study is directed towards a consideration of the instrumentalities of control of interstate pipe line facilities exercised at the hands of major or integrated companies.

The purpose of this study is fourfold: to show why and how Communism is emerging in China; to explain the special characteristics of the Chinese Communists and their tactics; to indicate the effect of Communism on the people of China; and to attempt an analysis of the attitude the Chinese Communists manifest toward the United States and Russia. Special emphasis will be laid upon the conflict between the Kuomintang (Nationalists) led by Chiang K'aishek and the Communists led by Mao Tze-Tung.
