From the Preface:

The 1921 bulletin is not offered as the result of a comprehensive and systematic study of the problems of oil shale, but rather as a selection from a large body of facts and results which have accumulated from somewhat disconnected, and at times incomplete investigations in field and laboratory work extending over a period of fourteen years. Several portions of the material here brought together had been used in addresses and in articles in various magazines and other publications.

The writer began his study of the shales in 1906, when he followed the southern outcrops of the shale beds from near Tucker, Utah, to Rifle, Colorado, collected samples of the shales and made a series of tests of the shales as possible future sources of oil, and as material for road building. After these first studies, except for a few tests of material sent to the Colorado Geological Survey laboratory, very little was done until 1915, when, at the request of certain officers of the United States Navy, the study was resumed in a more systematic and purposeful manner. A laboratory was fitted up with the essential apparatus for retorting, and the distillation tests were made in the University laboratories. But the pressure of other Survey work, especially during the war, tended to force the shale problems into the background.

This bulletin is organized into the following sections: Oil shales of Colorado; Shale oil problems; and Laboratory study of Colorado shales.
