A klippe of unmetamorphosed Devonian carbonate rocks rests on the Harrison Pass intrusive body south of Toyn Creek in the central Ruby Mountains, Elko County, Nevada. This klippe and other klippen of Carboniferous strata - first mapped by R. P. Sharp (1942) - that rest on lower Paleozoic strata are believed to represent a once-continuous thrust sheet...

Surveyor V landed on the lunar surface at 00:46:44 GMT on Day 254 (September 11), 35 hr after local sunrise on the moon. Between the time of landing and lunar sunset, 13 days later, it transmitted more than 18,000 high-quality television pictures of the lunar surface and parts of the...

A night-lighting unit, designed as a light weight back-pack, proved successful for capturing waterfowl pairs, pheasants (Phasianus colchicus), and cottontail rabbits (Sylvilagus floridanus) during the spring and summer when most breeding populations are widely dispersed. Eighty ducks of seven species were captured in 48 hours (1.7 ducks per hour) of...

In recent years beds of rock salt, as much as 820 feet thick, have been found in the subsurface of northeastern Thailand in a thick sequence of 'red beds' of the Maha Sarakam formation at the top of the Korat group of Mesozoic age. These salt-bearing rocks are widespread in...

An extensive deposit of white, granular, massive gypsum has been discovered in central Thailand. The gypsum, a part of the Mesozoic Korat group, was deposited along with salt by evaporation of sea water in shallow basins extensively developed in Thailand and adjacent parts of Laos. It now occurs in a...

One of the deepest water‐exploration wells in the southeastern United States was completed in 1966 at Jacksonville, Florida. It was drilled to a depth of nearly 2,500 feet to supply geologic and hydrologic information on the deeper unexplored part of the Floridan aquifer. This aquifer consists of a series of water producing zones separated by nonproducing zones. An important new fresh‐water producing zone was found, and the contact between...

The scope of area1 investigations of water resources in New York has changed within the last 4 years. Prior 1962, most investigations covered only counties or smaller areas and were mainly restricted to ground‐water resources Since 1762, investigarions have covered largebasin (2,000‐4,000 square miles) with the purpose of defining total water resources so that basin‐wldc comprehensive plans for water development can be prepared. Ground water has been intensively...

Twenty-six species of Tubificidae, 12 Naididae, and 1 Lumbriculidae were found in three regions of Lake Michigan- Green Bay, the southern end of the lake proper, and the harbor at Ludington, Michigan. One new naidid species is described. Methods of identification of some species are discussed and illustrated. The abundance...

Published data on the elemental composition of the Ectoprocta (Bryozoa) are supplemented by new chemical analyses of 28 ectoproct samples, distributed among 13 species, for organic matter, CO2 calcium, magnesium, strontium, barium, phosphorus and iron. The new data, in addition to the 25 fairly complete analyses previously published (distributed among 19...

The Sokoto basin in semiarid northwestern Nigeria contains Cretaceous and Tertiary semiconsolidated deposits that dip gently northwest off an oldland of pre-Cretaceous crystalline rocks. Until recent years the dug well has been the chief source of ground water for the Hausa cultivators and the pastoral Fulani inhabitants of the region....

Libya is situated on the Mediterranean foreland of the African shield. Marine strata of Paleozoic, Mesozoic, and Cenozoic ages abound in northern Libya, but continental rocks of Paleozoic and Mesozoic ages predominate in southern Libya. Marine incursions in Ordovician, Silurian, Devonian, Carboniferous, late Cretaceous, and early Tertiary times reached far...

The U.S. Soil Conservation Service is actively engaged in the installation of flood and soil erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found...

Counts were made of pollen in traps formed by enclosed bark in two remnants of bristlecone pine, Pinus aristata Engelm., from the White Mountains of east-central California. The traps, dated by tree-rings at A.D. 350 and 1300 B.C., contained a major complex of pine-sagebrush pollen and traces of other...

Investigation of 33 islands, scattered widely across the Caroline and Marshall Island groups in the Central Pacific revealed no emerged reefs in which corals had unquestionably formed in situ, or other direct evidence of postglacial high stands of sea level. Low unconsolidated rock terraces and ridges of reefflat...

Two small bodies of Precambrian basic intrusive rock in southeastern Missouri show uninterrupted differentiation of olivine diabase that produced ferrogabbro. Olivine diabase, foliated gabbro and coarse gabbro constitute the major textural rock types. Gravitational settling of plagio-clase, olivine and Fe-Ti oxides occurred in both intrusives and iron enrichment is a conspicuous feature. Plagioclase ranges from An58 to An35 and olivine varies from Fa36 to Fa57. Because these...

A sick mourning dove (Zenuidura macroura) collected in Maryland with 2 lead shot in the gizzard showed acid-fast intranuclear inclusion bodies in the kidney tubular cells. The liver and the tibia contained 72 ppm and 187 ppm lead (wet weight) respectively. Four gizzards from 62 doves killed by hunters contained...
