heavy overhead charges are taken into account the economy is 

 not so evident. The use of water power as a solution of the power 

 problem in the stone belt is out of the question. The only 

 available water power is the White river at Williams and this 

 power site is already in use. The amount of power that can be 

 developed at this point is given in the thirty-fifth annual Report 

 of the Indiana Department of Geology and Natural Resources

(p. 52), as 332 horse-power. This is not enough power to assist 

 materially in the quarry power plants, and at the present time 

 most of the water is used as cooling water in the condensers of 

 the steam plant erected at this place. 



From a purely thermal standpoint and as a means of conserv- 

 ing our natural resources, the producer-gas electric plant is much 

 better than the ordinary steam-electric plant for power purposes. 

 If fuel consumption were the only consideration there would be 

 no question as to its superiority over the steam plant, bu^ this 

 item is only one of many to be considered. Up to the present 

 time it has been the commercial efficiency of the steam plant that
