REPORTS OF THE PANEL CHAIRMEN 657 



6. State or regional compacts pertaining to surface mining, water 

 pollution, terrain damage, and land rehabilitation should be 

 encouraged. 



Because 50 Calif ornians attending this conference are thrilled by 

 the leadership of the President of the United States, and by the mo- 

 mentum that this conference has developed, we have sent the fol- 

 lowing telegram to the Governor of California, Edmund G. Brown: 



"President's Conference on Natural Beauty successful. Recom- 

 mend you take leadership for similar State conference earliest op- 

 portunity. Will undertake funding on modest basis." 



This is signed by 50 Calif ornians, headed by State Senator Fred 

 Farr and Assemblyman Edwin L. z'Berg. We would like to recom- 

 mend that other delegates ask that a similar conference on natural 

 beauty be planned for their State. 



The Underground Installation of Utilities 



The Chairman, Mr. CISLER. We are deeply impressed with the 

 progress being made in underground installation of electric utilities, 

 especially low-voltage distribution and service facilities. High- 

 voltage transmission lines are far more difficult to install under- 

 ground. However, substantial research and development work is 

 being undertaken on an industrywide basis. There is an increasing 

 awareness of the influencing factors involved in improving aesthetic 

 values. 



There is need for a clear understanding of the important distinc- 

 tion to be made between low-voltage distribution and service facili- 

 ties and high-voltage transmission facilities. Each must be considered 

 separately and distinctly as to technology, cost, construction, opera- 

 tion, and general relationship to the entire complex of an electric 

 power system of generation, transmission, and distribution from 

 source to consumption. Each must serve a separate and coordinated 

 function in order to provide economic and continuous supply. 



Our recommendations are, briefly, as follows : 



1. It is evident that much progress is being made in developing 

 and installing underground facilities to serve new residential projects, 

 in particular, those most favorable to effecting cost reduction. Pres- 

 ently the cost ratio in installation expense has been reduced to 1.5 

 for underground to 1 for overhead construction as compared to 10
