Slavery was established in Texas with the first Anglo-American settlement in 1822. The constitution of the Republic of Texas protected slavery as did laws passed by the legislature from 1836 to 1846, and the institution of slavery grew throughout the period. Slaves were given adequate food, clothing, and shelter for survival, and they also managed to develop a separate culture. Masters believed that slaves received humane treatment but nevertheless worried constantly about runaways and slave revolts. The Republic's foreign relations and the annexation question were significantly affected by the institution of slavery. The most important primary sources are compilations of the laws of Texas, tax rolls, and traveler's accounts. The most informative secondary source is Abigail Curlee's unpublished doctoral dissertation, "A Study of Texas Slave Plantations, 1822 to 1865" written at the University of Texas in 1932.

The isotopic and elemental composition of speleothem calcite precipitated from dripwaters in caves have been used to elucidate changes in karst groundwater flow paths and changes in climate such as shifts in vegetation and rainfall patterns. Given that recent studies have shown seasonal isotopic and elemental changes in cave dripwater chemistry, then these changes are most likely reflected in the precipitated calcite. This affirms the need to study the environmental controls on the dripwater isotopic and elemental chemistry on seasonal time scales, since ultimately these are environmental controls on the precipitated speleothem calcite. In this study, physical, chemical, and meteorological variations at 13 drip-water and pool sites in two cave systems in the Edwards aquifer of central Texas are used to delineate the controls on the evolution of cave waters. The chemical evolution of these cave waters can be accounted for by variations in calcite precipitation, soil geochemistry, flow paths, and degassing of CO₂ driven by seasonal overturn of the cave atmosphere.Calcite precipitated on glass substrates placed under three of the thirteen dripwaters in this study was analyzed for its C and O isotopic composition in order to assess 1) seasonal variations in the isotopic composition and 2) the extent to which precipitation occurs in isotopic equilibrium with its host dripwater. Each winter season, calcite growth rates increase, which corresponds to changes in the C and O isotopic composition of the calcite: higher ơ13C and ơ18O values during winter and lower ơ13C and ơ18O values during summer. Some calcite samples were found to precipitate out of C and O isotopic equilibrium, with maximum departures of 1.3% with respect to carbon and 1.4% with respect to oxygen. The results show that ơ13C and ơ18O in the modern speleothem calcite:1) can vary sub-annually without change in vegetation or climate, and 2) reflect in the majority of cases precipitation out of isotopic equilibrium with the host dripwater that precipitates the calcites. / text

This study revelaed that the rank of Texas with other state in the United States in the expenditure for schools per pupil is thrty-fifth. It further discussed that there are possible sources of taxation in the properties. However, there is a wide variation that needs to be studied. It further justify that present administrative and legislative trends in searching for new source of taxation makes the problem an important one.

This study aim to determine the bookkeeping systems in use in the retail and wholesale businesses in Denton, Texas, and to determine what improvements could be made in the bookkeeping systems of these businesses.

This thesis covers the history of education in Reconstruction Period Texas.

The electricity pricing structure in Texas has changed after deregulation (January 2002). The Energy Systems Laboratory has served as a technical consultant on electricity purchases to several universities in the Texas A&M University System since 2001. In the fiscal year of 2006 Stephen F. Austin State University joined with the TAMU campuses and agencies, and there are now 183 accounts in the Electric Reliability Council of Texas (ERCOT) North, Northeast, South, West, and Houston areas of Texas. From the 183 accounts, 9 Interval Data Recorder (IDR) accounts consume 92% of the total load. The objective of this research is to find the most economic price structure to purchase electricity for the Texas A&M System and Stephen F. Austin University by analyzing various pricing scenarios: the spot market, forward contracts, take or pay contracts and on/off season (tiered) contracts. The analysis was based on the 9 IDR accounts. The prices for the spot market were given by ERCOT and the other prices by Sempra. The energy charges were calculated every 15 minute using the real historical consumption of each facility and the aggregated load of all facilities. The result for the analysis was given for each institution separately, as well as for the aggregated load of all facilities. The results of the analysis showed that the tiered price was the most economical structure to purchase electricity for each individual university and for the total aggregated load of all 9 IDR accounts. From March 1, 2005 to February 28, 2006, purchasing electricity on the tiered price would have cost $13,810,560. The forward contract, that is, purchasing electricity on a fixed rate, was the next cheapest with an energy cost of $14,266,870 from March 1, 2005 to February 28, 2006, 3% higher than purchasing electricity at the tiered price. The most expensive method to purchase electricity would have been the spot market. Its energy costs would have been approximately $18,171,610, 36% and 31% higher, respectively, than purchasing electricity at the tiered price and the fixed rate.
