Lactation and weaning weight relationships were studied in 37 cows grazing Southern Utah irrigated pastures during the summer of 1979. The herd included 23 Hereford cows ranging in age from 2 to 12 years and 14 Simmental-Hereford half-blood cows aged 3 to 9 years. The suckling calves were sired by Hereford bulls. The average daily milk yield of 6.16 kg was affected by the cow breed. Simmental-Hereford cows produced 7.11 kg of milk per day, while the Herefords produced 5.21 kg per day. Milk production declined with increased days in lactation. The decline was linear in the Simmental- Hereford cows and quadratic in the Herefords. Milk production was also affected by the sex of the suckling calf. Heifer calves received 6.44 kg per day compared t o 5.80 kg per day for bull calves. Calf birth weight and test day weight influenced milk yield as cows nursing heavier calves produced more milk. Cow breed affected milk composition. Simmental-Hereford cows had higher percent solids-not-fat, while Herefords were higher for percent protein. Calf weights were affected by sex of calf. Bull calves weighed 33 .89 kg at birth, while heifers weighed 32.14 kg. At weaning, bulls weighed 188.63 kg, while heifers weighed 177.14 kg. While no breed difference was evident for birth weight, calves from Simmental-Hereford dams weighed more over the duration of the study than calves from Hereford dams. The difference between the mean 205-day adjusted weights for the calves from the Simmental-Hereford and Hereford cows was 24.96 kg (230.50 kg and 205.54 kg, respectively). Milk yield was highly correlated to calf gain (r 0. 71). The breed of dam influence upon weaning weight was largely a result of differences .in quantity of milk produced.

The battle over federal Wilderness designation of Bureau of Land Management lands in southern Utah has entered its third decade. Throughout this lengthy debate numerous stakeholders have maintained involvement, including members of Utah's conservation community. Two of the most prominent wilderness advocacy groups in Utah are notable not only for their sustained involvement with the issue, but also for their divergent positions on how to resolve this public land dispute. This research examines those two organizations, the Utah Wilderness Association and the Southern Utah Wilderness Alliance, through an analysis of their respective structural, organizational, philosophical, and tactical perspectives. Ultimately, the background of each organization's leadership, their organizational structures, their ability to mobilize resources, and their distinctive wilderness philosophies offer an understanding of how each organization perceived its mission and its ability to provide a construct for resolution of the Utah Wilderness debate.

In the field of physical education there has been formulated by leading physical education authorities an ideal program for use· in high schools, but this program cannot always be used in our high schools because of certain problems that are always present. However, we can adopt the ideal program and modify it to fit any situation that may arise in the various schools. The physical education program is an unstatic program. It is always changing with the changing philosophy of physical education.

Substantial comparative analyses of Puritanism and Mormonism are lacking in historical scholarship, despite noted similarities between the two religions. This study helps to fill that void by comparing the Puritan and Mormon proselytization efforts among the Indians that occurred at the respective sites of Massachusetts Bay Colony and the Southern Indian Mission. In my examination of the missionization attempts that took place at these two locations, I analyze a common motive and method of the two denominations for attempting to Christianize the Indians. The Puritan and Mormon missionaries proselytizing in Massachusetts Bay Colony and the Southern Indian Mission shared an identical motive for seeking to convert the Indians to Christianity. The missionaries' conviction that the regional natives were descendants of the House of Israel prompted them to proselytize among the Indians, as they understood that the conversion of the House of Israel constituted one of the important events to precede the prophesied return of Christ to the earth. The Puritans and Mormons engaged in and overseeing the missionary endeavors of the two locales under study likewise shared several parallel conversion methods. One such method consisted of utilizing one of the largest resources available to the two religions: their constituents. The Puritans and Mormons each implemented the association and example of their missionaries and congregational members as a primary method of conversion. Moreover, they applied that technique in a corresponding manner.

Riedel shear zones are geometric fault patterns commonly associated with strike-slip fault systems. The progressive evolution of natural Riedel shear zones within the Navajo Sandstone of southern Utah is interpreted from the spatial evolution of small-scale, incipient Proto-Riedel Zones (PRZs) to better-developed Riedel shear zones using field mapping and three-dimensional digital modeling. PRZs nucleate as a tabular zone of localized shearing marked by en èchelon deformation bands, each of which is no more than a few mm wide and tens of cm long, and oriented at 55° - 85° to the trend of the zone. With increasing strain, deformation bands and sedimentary markers are sheared ductily through granular flow and assume a sigmoidal form. The temporal and spatial evolution of bands comprising a Riedel shear zone suggests that PRZs nucleate as transitional-compactional deformation bands under localized, supra-lithostatic fluid pressure. Subsequent bands develop under modified regional stresses as conjugate shear fractures within the strain- hardened axis of the PRZ. These antithetic driven systems are not compatible with traditional synthetic driven models of Riedel shear zones. Unlike most synthetic driven examples, these antithetic driven systems are not controlled by preexisting "basement" structures, thus their geometries reflect a primary propagation or secondary passive deformation mechanism.
