Page ii - As the subtitle indicates, the papers included are of two classes — (1) short papers giving comparatively detailed descriptions of occurrences that have economic interest but are not of sufficient importance to warrant a more extended description; (2) preliminary reports on economic investigations the results of which are to be published later in more detailed form.

The different strata of the series are not always continuous, a stratum of sandstone giving place to one of shales and vice versa. This is especially true of the upper two-thirds of the beds. The lack of continuity in the different strata has rendered it well nigh impossible to establish any definite horizons in the upper members of the series. All the deposits of...
