An Autunite Deposit in the Rosamond Hills, Kern County, California
From introduction: An autunite deposit in the SW 1/4 sec. 25, T. 10 N., R. 13 W. San Bernardino meridian, was visited by F. M. Chace on May 6 and 15, 1950. The deposit is about 100 yards west of a north-south country road and is at an altitude of approximately 2,775 feet. The autunite-bearing tuffaceous sandstone strikes N. 35-40 W. and dips 20 -25 SW. It has been traced about 40 feet along the strike at the base of the outcrop and for about 20 feet up the dip. Insufficient work was done to give an accurate idea of the size of the deposit or to determine if other autunite-bearing beds are present.

Chromite and quicksilver deposits of the Del Puerto area, Stanislaus County, California
From Introduction: "The present report is based on 10 weeks of field work from mid-November 1940 until late January 1941, and 4 days in May 1941. An area of 5 1/2 square miles in and about Del Puerto Canyon was mapped on a scale of 600 feet to 1 inch, and two small areas in the vicinity of the Adobe Canyon and Black Bart chromite mines were mapped on a scale of 200 feet to 1 inch."

The Coso Quicksilver District, Inyo County, California
From abstract: The Coso quicksilver district, which is in the Coso Range, Inyo County, Calif., produced 231 flasks of quicksilver between 1935 and 1939. The quicksilver mineral, cinnabar, was not recognized in the district until 1929, although the hot springs near the deposits have been known since about 1875...The granitic rock on which much of the sinter rests is considerably altered. The cinnabar was deposited as films and grains in open spaces in the sinter, during one stage in a sequence of hot spring activities that still continues. The amount of sinter in the district is estimated to be about 1,800,000 tons. Although the greater part of this does not contain much cinnabar, the total quantity of such material is large enough to be of interest as a low-grade ore.

Geology of the Kettleman Hills Oil Field, California: Stratigraphy, Paleontology, and Structure
From Introduction: The field work that furnished the basis for this report was begun in 1930 and was continued at intervals until 1934. The anticlinal character of the Kettleman Hills is apparent to even the casual observer, but the many structural complications due to an intricate network of minor faults, at least in North Dome and Middle Dome, are much less obvious. Though it is improbable that these faults have any relation to the occurrence of oil, an attempt was made to map them, not only to represent the structure adequately but also because the stratigraphy could not be understood if they were neglected. Faunal zones were particularly useful in mapping. On the other hand, some lithologic units proved to be more persistent than had been expected. The two sets of features-fossils and lithology-served as checks on each other.

Manganese Deposits in the Paymaster Mining District, Imperial County, California
Abstract: The manganese deposits of the Paymaster district, in Imperial County, Calif., extend along steeply inclined normal fault fissures which cut Tertiary (?) volcanic breccia and fanglomerate. The ore deposits are in part open-space fillings composed largely of psilomelane, and in part fault breccia replaced by psilomelane, pyrolusite, and manganite. Calcite and rock fragments are the chief impurities. High-grade ore now exposed averages about 40 percent manganese, and contains much barium. About 3,000 tons of ore averaging 42 percent manganese was produced from the district by hand-sorting in 1917-18. It is estimated that nearly the same amount could be produced again, largely from present workings. In addition, a few tens of thousands of tons of milling ore, estimated to contain between 10 and 30 percent of manganese, are believed to exist in veins one to three feet wide within one or two hundred feet of the surface.

OK, USA: A Musical Guide Book to the States: Soldier Shows "Blueprint Special"
The last of the U.S. Army Soldier Shows "Blueprint Specials" to be published, "OK, USA" is a musical revue on the theme of U.S. soldiers returning to the United States and finding it finding it as foreign and exotic as any country overseas because they have been away and living under extreme circumstances for so long. Like the other "Blueprint Specials," this show includes a complete script (multiple copies this time); a conductor's score and complete set of instrumental parts; a sample program; set and costume designs; and detailed instructions for producing the show using whatever materials are at hand. Unlike the other "Blueprint Specials," it includes no information on the librettists, songwriters, and other staff who worked on the show.

Quicksilver Deposits of the Parkfield District, California
From abstract: The Parkfield district, one of the minor California quicksilver districts, lies on the southern end of the Diablo Range, in the southeastern part of Monterey County and the westernmost tip of Kings County. (...) Two geologically similar areas, separated by 10 miles of unmineralized rocks, have been mapped. These areas contain (1) sedimentary, volcanic, and metamorphic rocks belonging to the Franciscan formation, of probable Jurassic age, (2) sedimentary rocks of Cretaceous age, (3) a few outcrops of fossiliferous strata assigned to the Temblor formation, of middle Miocene age, (4) large masses of serpentine emplaced along fault zones in post-Miocene time, (5) lenses of silica-carbonate rock formed by the alteration of the serpentine, and (6) large areas of landslide.

Soil Defense in the Pacific Southwest
"The Pacific Southwest, as considered in this bulletin, embraces the two States -- California and Nevada. Evidences of soil and water losses are briefly touched upon, as are the factors contributing to these losses. The bulk of the bulletin deals with measures of defense that are now being employed on farms and range land within project areas of the Soil Conservation Service and in areas where members of Civilian Conservation Corps camps have been assigned to erosion-control activities." -- p. i. Some of the measures discussed include the use of cover crops, contour farming, crop rotation, subsoiling, strip cropping, and terracing.
