A study of the humus content and the water content of San Saba clay and Denton clay. Studies show that the physical properties of soil are conducive to moisture retention and the availability of moisture to plants.

This thesis describes the growth and feeding habits of large mouth bass (Huro salmoides) as observed in North Texas.

This thesis presents the results of a three year study devoted to discovering the life and phenomena found in Lake Worth near Fort Worth, Texas.

This thesis presents the results of an investigation conducted to determine the maturation stages and chromosomal composition of the Homophron americanum (Sand Beetle) found in North Texas.

This study is an attempt to determine the relationship between humus and the water found in it and how both effect soil in Denton county, Texas.

A study of hypersensitivity of high school students to the oleoresins of fifty common North Texas plants.

This paper deals with a study of the chresard, percolation, and capillarity of twenty representative Denton County soils. The group of soils chosen vary greatly in texture thus affording excellent material for comparative studies of edaphic factors based upon this property.

In this research, study was made of representative soils of denton County (Texas) with the aim of correlating various soil-moisture factors through experimental analyses. Two accepted hypotheses of soil-moisture relations have been substantiated by experiment with Denton County soils.

The purpose of this study is to determine the influence of chemical, physical, and bilogical factors on th seasonal variation in population and on reproduction of Chlorohydra Viridissima (Schulze) in a small pernnial pond.

This thesis attempted to study the bottom productivity both qualitatively and quantitatively with reference to the distribution of bonthos. The study of the bottom fauna in large reservior lakes is a relatively new field. This work will give more information on an unknown field than previously existed, although its scope is not intend to be exhaustive.

The purpose of this study was to correlate the Vegetation of the Woodbine Sands with the edaphic factors. In the laboratory an analysis of the edephic factors was made of the twenty-two soil types collected from the three formations. The results of these and other analysis are shown in tables and graphs. The results indicate that the vegetational cover of an area that is uniform in its origin and in its resident soil factors is determined by the edaphic factors present.

The purpose of this study is to observe the frequency of occurrance of members of the colon group in various brands of milk, milk products, and soft drinks marketed in the city of Denton, and to determine the total number of bacterial organisms occuring in these products from week to week.

This study was a comparative study of Plankton of Lake Dallas and the three main source streams. Based on the analysis of data, which was presented relative to the organisms taken from the lake and from the source streams, the results obtained are discussed, the Plankton seem to be largely autogenetic in Lake Dallas, the source streams Elm Fork and Clear Creek form a dilution process.

The aim of this study has been to measure some of the ecological factors in a series of plant habitats and their relation to the existing vegetation in selected twenty soil types of Red River County, Texas.

This study attempted to examine representative soils of Denton County in an effort to determine seasonal and soil type variations in the fungous flora both quantitatively and qualitatively.

This study attempted to determine whether ova are formed from the epithelial covering of the ovary during sexual maturity, and if so to determine how they are formed and to see if there is any relation between the formation and the breeding season.

The aim of this study is to determine what factors are most important in controlling the number of bacterial colonies found in twent represntative Denton County (Texas) soils during the growing season.
