Article discusses the life of the Chitwood family on the Oklahoma frontier in Greer County. Adelia Clifton's adapted version of Maggie Chitwood Kilpatrick's manuscript includes stories cattle herding, conditions in the dugout house they lived in, and early education.

Article provides an introduction to and includes the memories of Sarah Ann Harlan, a pioneer woman who was able to live in the Choctaw Nation with her husband on account of her heritage. Harlan's account includes stories of her family and upbringing on a plantation near the Alabama-Mississippi state line.

Article describes early territorial legislation requiring segregation in public schools in Oklahoma. Frank A. Balyeat discusses his own recollections of the time period, how some schools remained mixed, and the history of education on the frontier.

Article provides a biographical tribute to judge, lawyer, and newspaper editor Judge Baxter Taylor. Edward M. Box explores the highlights of Taylor's life and career.

Techniques are described for obtaining x ray diffraction information on active metals at high temperatures. One method is used to 1000 deg C with rare earths; the other method is used to 2200 deg C with tungsten, and to 1400 deg C with some f the higher melting rare earths. The latter approach permits simultaneous measurement of resistance of the specimens vs temperature and the diffraction pattern, which facilitates the characterizing of the high temperature forms of the metals.

A back-reflection Laue camera with three rotation axes and three orthogonal translation axes is described. This camera allows the alignment of large single crystals with a precision of plus or minus 0.25 deg . The degree of single crystallinity of a specimen may be examined. In addition it is possible to accurately mark a crystal for subsequent utilization. (auth)

Recently a T = 1 resonance in the {Lambda}{pi} system called Y*{sub 1} has been observed with a mass of 1385 Mev. Two types of resonances have been predicted that might relate this observation to other elementary-particle interactions: (1) P 3/2 resonances in the {Lambda}{pi} and {Sigma}{pi} systems predicted by global symmetry corresponding to the (3/2, 3/2) resonance of the {pi}N system; (2) a spin-1/2 Y-{pi} resonance resulting from a bound state in the KN system. The position and width of the observed Y*{sub 1} resonance agree with both theories, but since the spin and parity have not yet been determined, it is impossible at present to distinguish between the two theoretical interpretations.

Two types of electron polarization operators are surveyed. A three- vector operator is described that is appropriate for calculations involving plane- wave states. A four-vector operator is described that can be used for taking account of external electromagnetic fields. (T.F.H.)

The beta spectra of In/sup 114/, P/sup 32/, and Y/sup 90/ were stud ied closely in an intermediate-image beta-ray spectrometer and compared to theoretical predictions in terms of a linear shape factor of the form (1 + aW). The values obtained for a were s for P/sup 32/, and (-0.0047 plus or minus 0.0008)/mc/sup 2/ for Y/sup 90/, all for electron kinetic energies from about 200 kev up to near the maximum beta energies. Tests were made to give indications for spectrometer fidelity. Because of the linearity of the shape-factor plots and the similarity in energy range, the comparative results from In/sup 114/, P/ sup 32/, and Y/sup 90/ are tak en as a definite indication that for at least two of these activities the shape factors have nonzero slopes, irrespective of questions of instrumental fidelity.

Article discusses the activities of Comanche raiders on their plunder roads that swept from Kansas to Mexico. Ralph A. Smith focuses on their exploits below the Rio Grande from 1843-1844.

Article introduces and includes the description of Lieutenant William W. Averell's journey from the Washington D.C. to Fort Smith at the outbreak of the Civil War carrying an order from the War Department. Muriel H. Wright explains the contents of the order, which was the withdrawal of troops from Indian Territory, and what it meant for the people of the area.

Article provides a continuation of the letters of William E. Burnett, an officer in the U.S. and later Confederate Army. In this third part of Raymond Estep's article, the removal of American Indians from Texas and the founding of Fort Cobb are highlighted.

Notes and Documents column including a document about the life and career of American Indian artist Acee Blue Eagle and the quarterly staff report of the Oklahoma Historical Society.

This section includes the minutes of quarterly meeting of the Board of Directors of the Oklahoma Historical Society that was held on January 26, 1961.

Article provides a summary of the survey of historical materials related to the De Soto Expedition taken by the United States government, and the findings with regard to whether or not Hernando de Soto entered Oklahoma during his travels.

Article explores the life and work of the author's great-great-grandfather, William L. McClellan, agent of the Choctaw Nation in the early nineteenth century. Ben Collins Pickett's uses correspondence from the time to construct a picture of McClellan's operations as he procured his appointment and constructed the Choctaw Agency building.

The electrical resistivities of polycrystalline samples of La, Pr, Nd, and Sm are reported in the temperature range 1.3 to 300 deg K. La exhibits a superconducting transition at 5.8 deg K. The curve for Pr has slope changes at 61 and 95 deg K. The Nd curve shows small jumps at 5 and 20 deg K. Sm shows slope changes at 14 and 106 deg K. (auth)

Safety precautions utilized for control and cominement of fissionable and radioactive materials in the various aqueous reprocessing operations performed at the Idaho Chemical Processing Plant are presented. Three primary nuclear safety controls, geometrical, mass limitation, and concentration control, are used. Operations are penformed according to standard operating procedures which are set up to prevent circumvention of the primary nuclear safety controls. The various processing operations with their particular safety features are discussed. The operations include receipt, handling, and storage of irradiated fuel elements, dissolution of the fuel elements in various reagents, separation of the unburned fissionable material from fission products and fuel element structural materials by solvent extraction, salvage or recycle operations of off- specifications product or waste solutions that exceed the dispossble fuel concentrationalimits, product packaging, storage and shipment, fission product recovery, and waste collection, handling and disposal. The originai plant design and later additions and modifications included built-in geometrical control wherever practical with allowances for possible neutron interaction between vessels. The standard operating procedures specificaily state mass limits and concentration controls required for certain operations which involve appreciable quantities of uranium. Administrative control insures compliance with the standard operating procedures. (auth)

The interaction Hamiltonian for the Coulomb exchange effect between conduction electrons and magnetic-shell electrons in rare-earth metals was derived from first principles. The approximations under which the interaction can be represented by the product of electron and ion spin vectors are exhibited. (auth)
