Excerpt from The Oil Shale Industry To describe an industry which is still in its primary stage is not an easy task. Without definite commercial results to record, without well established processes to describe, and with information on all phases of the subject widely scattered and known only to the particular persons interested, the preparation of the present volume has been difficult. However, the recent striking demand in industrial life for oil in its many forms, the failure of domestic wells to meet this demand in full, the rapid advance in the price of petroleum, the warning of geologists and government experts that the underground supply of oil cannot much longer be depended upon to supply the ever increasing demand, all unite in pointing unerringly to the one permanent supply of the raw material which we have – the deposits of oil shale. Whether we wish it to be so or not, we shall soon be forced to resort to the oil shales for our supply of oil.
