AbstractFrom beginning of text: The past year is one in which no spectacular results have been obtained, but a year in which substantial and far reaching fundamental progress has been made. Effective legal progress has been made in securing valid title from the Government; extensive experimental work has been done on retorting; chemical investigation on the nature, properties, and behavior of oil shale has been carried on; the problems of refining shale oil have been taken up by oil refiners and chemists, and, finally, large financial interests, especially the oil and mining, have recognized that the oil shale industry is worthy of their closest attention.
