The Box Elder Bug, Leptocoria trivittatue (say), is a hanipterous insect belonging to the family corisidae. Although it rarely is a pest of agricultural crops, its habit of invading homes and other buildings for hibernation and to warm itself has made it an annoying household pest. It has proven to be a difficult insect to control. Only a few of the contact insecticides, useful in control of related insect pests, have given satisfactory control of the Boxelder Bug. Because it has not been considered a critical problem, it has not received detailed attention from the scientific investigators. Its close association with boxelder trees has long been recognized. Elimination of boxelder trees has often been advocated for control of this insect. However, boxelder is not its only host and, furthermore, elimination of boxelder trees is not always practical or desirable.

One of the fundamental needs of elementary school children is to develop their motor systems by means of physical activities adequately suited to their representative age groups. In so doing, opportunities are provided for sociological and psychological requirements essential in developing a healthy, confident individual capable and willing to accept social and family obligations and responsibilities. This infers that an essential function of the school is to provide appropriate areas, facilities, and equipment for such activities. It also suggests that the playground be an integral element of a modern school.

Several volcanic flows lie between Death Creek and Dairy Valley Creek, near Etna, Utah. The major, central portion of the volcanic flows is composed of dacite and dacite vitrophyre. An elongate ridge in the southeastern corner of the study area and several small outcrops in Death Creek Valley are composed of rhyolite and rhyolite vitrophyre. Additional rock types include conglomerate, volcanic ash, and tuffaceous sedimentary rock of the Tertiary Salt Lake Formation, Paleozoic limestone, and Tertiary basalt. Dacite and dacite vitrophyre samples are porphyritic, containing phenocrysts of plagioclase, quartz, biotite, amphibole, orthopyroxene, and iron-titanium oxides. Rhyolite and rhyolite vitrophyre samples are porphyritic, containing phenocrysts of plagioclase, alkali feldspar, quartz, and iron-titanium oxides, with minor amounts of biotite and amphibole. Plagioclase phenocrysts are complexly twinned, zoned, and corroded in dacitic samples; whereas, they are simply twinned, unzoned, and uncorroded in rhyolitic samples . Quartz and alkali feldspar phenocrysts contain glass-filled inclusions and are subrounded in rhyolitic samples. Average chemical analyses of five dacitic sample yield weight percent: SiO2, 69.11; TiO2, 0.31; Al2O3, 14.18; Fe2O3, 1.26; FeO, 1.23; MnO, 0.04; MgO, 0.54; CaO, 2.27; Na2O, 3.30; K2O, 4.07; P2O5, 1.23; H2O+, 1.89; H2O-, 0.46; total, 99.27. Average chemical analyses of three rhyolitic samples yield weight percent: SiO2, 76.66; TiO2, 0.12; Al2O3, 11.80; Fe2O3, 0.58; FeO, 0.43; MnO, 0.01; MgO, 0.09; CaO, 0.78; Na2O, 2.69; K2O, 5.26; P2O5, 0.02; H2O+, 1.17; H2O-, 0.22; total, 99.85. The volcanic flows of the study area are believed to be derived from fusion of sialic material within the crust which differentiated to form dacite and rhyolite. The dacite is believed to be the first magma extruded in the study area; whereas, the rhyolite represents the later extruded magma. Evidence supporting this relative emplacement is the restriction of rhyolite to the southeastern corner of the study area and the intrusion of rhyolite into dacite in the narrows of Death Creek Valley. The volcanic flows of the study area are believed to have been derived during the second stage of Basin and Range volcanism beginning approximately 14 million years ago. The study area rhyolite has chemical compositions similar to those rhyolites of bimodal basalt-rhyolite fields formed during the second stage of Basin and Range volcanism which includes high silica contents, higher alkali to calcium ratios, and greater sodium contents compared with rhyolite of calc-alkalic fields.

Two basalt flows and an andesite fissure eruption occur in the Rozel Hills - Black Mountain area in Box Elder County, Utah. Both basalt flows are aphanitic, and contain olivine, plagioclase, augite, and opaque oxides. They may be distinguished both chemically and on the basis of their textures. Unit 2 basalt is finer grained, and appears to be associated with a fault in the Black Mountain area. Chemically, it is similar to high-iron lavas in the Craters of the Moon, Idaho area. It has higher alkali, total iron, and titanium contents that Unit 1 basalt. Unit 1 basalt is similar to other tholeiitic basalts in the Basin and Range province. It is coarser-grained and has higher silicon, magnesium, aluminum, and calcium contents than Unit 2 basalt. While the basalts have characteristics of alkali-olivine basalts, such as absence of calcium-poor pyroxene, and a high alkali to silica ratio, both units are hypersthene- and olivine-nonnative and classified as olivine tholeiites. Subsurface basalt in the area appears to represent both lava types, but extensive alteration makes comparison difficult. Andesite from the area is aphanitic, and contains plagioclase, orthopyroxene, and opaque oxides. Temperatures of equilibration calculated from co-existing magnetite and ilmenite range f rom 1148°C to 745°C for basalt. Temperatures calculated from co-existing olivine and clinopyroxene range from 1009°C to 994°C. While the two basalt units cannot be related by fractional crystallization at surface conditions, some parent - daughter relations are likely within each unit, and the andesite is most likely a differentiation product of Unit 1 basalt. Partial melting of pyrolite and spinel lherzolite mantle compositions to produce Unit 1 and Unit 2 basalts was investigated. Since no unique temperature and pressure of equilbration for these melts and residu~l material from each mantle type was found, it is concluded that partial melting of a mantle of pyrolite or spinel lherzolite composition did not produce these lavas. Unit 2 basalt may be derived from Unit 1 basalt by fractionation of high pressure (8 kb) phases. This mechanism, similar to that proposed for the Craters of the Moon - Snake River Plain system, may account for an evolved basalt (Unit 2) with a lower silica content than a less differentiated basalt (Unit 1).

The purpose of this study was to continue the assessment of low-temperature geothermal resources in Utah started . by the Utah Geological and Mineral Survey. The area of interest with in this report is north-central Box Elder County, Utah. Exploration techniques used included chemical analyses of water from wells and springs, temperature surveys, and temperature-depth measurements in unused wells within the study area. The highest water temperatures (31, 30, and 290c) recorded in this research were located in three separate geographic regions, suggesting that no single warm water occurrence dominates the study area. Total dissolved solid (T:DS) concentrations ranged from 294 to 11,590 mg/1. Areas of warm water occurrences generally had TDS values of greater than 1,100 mg/1. Three water types were distinguished using trilinear plots of common ion analyses of collected water samples. The warmest wells were of Type III water character, which has high (>75%) sodium and chloride concentrations. Reservoir temperatures were estimated using the water chemistry. Both the silica and the Na-K-Ca geothermometers were used to calculate reservoir temperatures, averaging between 500c and 1 ooo c. If mixing effects are taken into account, reservoir temperatures might be as high as 198°C. Temperature-depth measurements were logged in 16 unused wells. Thermal gradients calculated from the profiles ranged from isothermal to 267oC/km. The background gradient for the study area appears to be slightly above the average Basin and Range gradient of 35oC/km. The highest gradients were calculated for the area approximately 8 kilometers west of Snowville, Utah, which is also an area of warm water. Several areas of possible low-temperature geothermal interest have been identified in the study area by considering water temperatures, calculated reservoir temperatures, and temperature-depth data. However, additional work is needed to more accurately define the possible geothermal resource in these areas.

Attitudes of caseworkers and supervisors in public welfare agencies were studied with regard to the following subjects: (1) the public assistance program in Utah, (2) the welfare recipient, (3) family planning as a means of dealing with poverty, (4) government participation in the public assistance program, (5) methods of rehabilitation, (6) community support of welfare agency, and (7) positive and negative aspects of casework. Data were analyzed statistically with regard to age , education , political preference, and sex. An analysis of variance was made, and the F test applied to determine significance levels . Caseworkers and supervisors responded positively toward the public assistance system in Utah with mean scores high enough to indicate approval though not complete approval of this system. Caseworkers and supervisors expressed a slightly positive attitude toward welfare recipients; they were generally favorable toward family planning as a means of dealing with poverty; and they expressed a positive attitude concerning government participation in the public assistance program. Df the three means of rehabilitation proposed, caseworkers and supervisors unanimously selected the use of individual therapy as their first choice, environmental change and direct financial aid as their second and third choices, respectively, by the majority of respondents . Caseworkers and supervisors felt a need for community support but did not feel they received it. In their opinion the public is poorly informed, has many misconceptions, and is, consequently, negative toward the public assistance system. Male and female caseworkers and supervisors indicated that working with people and helping them with their problems were the most enjoyable aspects of their job; whereas, clerical work and administrative rules and procedures were the least enjoyable aspects. Women liked more aspects of their work than they disliked; whereas, men disliked more aspects than they liked.

The production of canning peas has an important place in the economy of Utah, partioularly in the counties along the wetstern slopes of the Wasatch Mountains. The enterprise is one which adds intensity to Utah's small farms. This intensification is accomplished with little additional equipment or labor other than that owned or supplied by the farm operator and his family. The crop is seeded in early spring and harvested in early summer leaving the ground available for summer fallowing or planting to a short season crop such as grain pasture. Peas are a satisfactory nurse crop for small-seeded legumes such as alfalfa.
