Preparation of a desk-side reference manual of Cretaceous foraminifera was undertaken as a project of the Bureau of Economic Geology, where I was a staff member during the summers of 1945 to 1947 and during July of 1951. Although the Handbook is intended primarily for the advanced college-level student and routine commercial laboratory micropaleontologist, it should be useful as well to the specialist. The accuracy of a compilation of this kind is never greater than that of the sources from which it is taken, and errors of transcription and interpretation are unavoidable.

A deposit of phosphorite, estimated to be 11 feet thick, was found March 26, 1952, while the writer was mapping ancient sink fillings and collapse structures within the outcrop area of the Honeycut formation south of Marble Falls, Texas. The phosphorite is exposed in a road material pit on the eastern side of a Carboniferous outlier. It rests on shale typical of that in the Barnett formation of Mississippian age and is beneath spiculitic limestone at the base of the Pennsylvanian Marble Falls limestone.

Wendel quadrangle is entirely within the Edwards Plateau province and is situated southwest of the Llano region.

The geology of the Wendel quadrangle is shown on a planimetric map, and the only topographic map available is the reconnaissance 30-minute Kerrville quadrangle. Elevations ranging between 2,041 and 2,284 feet were determined during traversing for control, but neither the highest nor the lowest elevation was reached. However, it is estimated that the relief within the quadrangle is about 270 feet, ranging between 2,020 and 2,290 feet.
