This study is a report of the results of a series of experiments, the purposes of which were to determine: (1) what natural pigments are available in Denton County, Texas, (2) the variety, quality, and quantity of the native pigments as compared with standard commercial pigments, and (3) the suitability of these native pigments for use in the preparation of artists' colors. Since the chief interest was in the specific hues, their quality and variety, the factor of commercial possibilities was not investigated.

The problem with which this investigation was concerned was the comparison of cedar elm populations in different stands along creeks in Denton County, Texas, and the relationship of certain population parameters to various substrates present at stand sites, Parameters investigated eluded average basal area, basal-area density, transect-segment density, intertree distance, lateral distance, frequency, diameter breast-high, diameter breast-high size-class distribution, and immature-tree density. Variations among populations of Ulmus crassifolia Nutt were noted and analyzed in terms of soil particle size and existing community conditions.

This study investigates the use of oral interpretation in social contexts. The context chosen was a community corrections program which provides education and employment assistance to adults on probation in Denton County, Texas. A solo interpretation script was incorporated into a public awareness presentation about the Denton County Probationer Education and Employment Program. The presentation was presented to a pilot audience to test the effectiveness of combining oral interpretation with public speaking to inform audiences about and elicit support for community corrections. It was determined that integrating an interpretative performance into an informational presentation is an effective method of employing oral interpretation outside the classroom and expanding its rhetorical dimensions.

The purposes of the study are to determine the status of educational opportunities in Denton County, based on latest available data, and to make definite recommendations for needed improvements which would aid materially in equalizing educational opportunities for Denton County's children. The study is an important one, since solution of it will be a basis for serious thinking to the end that more nearly equalized educational opportunities may result.

Sorghum plants excrete phenolic acids which reduce subsequent crop yields. These acids accumulate in field soil by combining with soil and clay particles to form stable complexes which remain until degraded by bacterial metabolism. The amount of phenolic acids in soil samples were obtained by gas chromatography measurements, while Azotobacter populations were obtained by plate counts in 40 sorghum field samples from Denton County, Texas. One can conclude that increasing the Azotobacter population in the soil increased the degradation rate of phenolic acids proportionally. It is proposed that seed inoculation will introduce selected strains of Azotobacter into the soil. The presence of Azotobacter should increase crop size in subsequent plantings.

"In the first fifty years of the twentieth century, Denton County's chief asset was the fertility of its land. Today the county's main asset is still its land but for a different reason. As industry decentralizes, as the city populace searches for new areas of settlement, as the county's educational institutions expand, as investors look for new tracts of land, as builders construct large interstate highways, and as digging machines create lakes and recreational areas, the principal asset of the county becomes the non-agrarian utility of its land. Accompanying this land value shift has been an occupational change."-- leaf 103.

"As a means of defining the purpose of the problem, the following objectives were considered: (1) to list the species of birds observed in Denton and neighboring counties; (2) to assign a descriptive status to each species; (3) to estimate the relative abundance of each species (4) to annotate the list with data from other sources, when additional data provide a more accurate and complete description of the status of the species in Denton County; (5) to designate the section of the county in which each species was most frequently observed; and (6) to briefly summarize the changes in bird populations during the period 1950-1956, and to suggest some hypotheses which help explain these changes." -- leaf 6.

"The area of study was restricted to those common flowering herbs of Denton County, Texas, which have conspicuous flowers or a conspicuous flower cluster. There were, however, many plants included in this flora which are common to several counties of north-central Texas. Since there has been no previous key devised for the herbs of Denton County, Texas, the purpose of this key was to provide a flora which could be used by elementary and high school instructors, as well as any other interested persons who lack an extensive knowledge of botanical nomenclature." -- leaf iv.

"There are many factors that influence the achievement of school children; however it is rather difficult to determine the effect of each because of the close relationship and probable overlapping of the various factors. The problem in this study is to determine what effect the size of the school, training and qualifications of the teachers, and sex have upon the achievement of elementary school children in Denton County. A few of the main factors involved in this study will be examined and statistically presented, so as to show their relation to the achievement of the rural children in Denton County, as revealed through the Harlow achievement tests."-- leaf 1.

"In order to determine the extent to which the Denton County Free Library is meeting the needs of the elementary school children for recreational reading, an analysis was made of the reading interests of the elementary-school children of twelve common school districts of Denton County, Texas. The ages of these children ranged from nine to fourteen years. A second analysis was made by checking various acceptable authors in the field of children's reading interests as read by the children in this group and age level. This information was secured by having each child in the schools check the items listed in a school survey sheet. This information was tabulated and the results are shown in tables presented in Chapter III. A third analysis was made of library material found in the reading lists that were supplied by the county; and lastly, a comparison was made of the results of the last analysis with the two preceding ones." -- leaf 3
