The scope of this study is limited to Federal military occupation during the five years from 1865 to 1870. Only the interior counties, where a dense Negro population required the exercise of political and social responsibilities, will be considered in detail. A line from Wise through Bosque, Travis, Wilson, Karnes, and Goliad Counties to the coastal town of Corpus Christi would roughly separate interior from frontier posts.

Accurate identification is fundamental in any study of grasses by farmers, ranchers, range specialists, ecologists, or students interested in the changes taking place in the grass habitat. Frequently it is convenient, and sometimes it is necessary, to identify the grasses by their vegetative characters. Some are readily recognized at a glance by their habitat and certain characters well known to the experienced observer. In other cases, identification is more difficult; and, perhaps with a few, it is impossible to be certain of the species from vegetative characters. However, this may also be true when the characters of the floral parts alone are considered. The inflorescence, used in most keys and descriptions, is often available only for a short period of time. Identification by the characters of the vegetation can be used throughout the growing season, even if grazing or mowing has removed or prevented the development of the floral parts. There have been other studies of grass identification related to vegetative characters, but they have been local and have not covered North Central Texas. This paper provides a means of identifying grasses by their vegetative characters. It can be used by the scientist, the technician, and the layman interested in …

The development and refinement of FA has been adequately investigated with major emphasis on pathogenic microorganisms. The development of this technique has reduced both the time and number of biochemical tests necessary to identify a diversity of organisms. The organisms included are the protozoans, as described by Goldman (1953 and 1957) and by Ingram (1961), viruses, as reported by Liu (1955a) and Burgdorfer and Lackman (1960a), pathogenic bacteria which have been investigated by Moody, Goldman, and Thomason (1956), Moody and Winter (1959), Deason, Falcone, and Harris (1957) and Thomason, Cherry, and Moody (1957). Various fungi have been studied with FA by Kaufman and Brandt (1964), Kaufman and Kaplan (1961 and 1963) and Gordon (1958). Therefore, due to the success of the fluorescent antibody technique in many areas of microbiology in previous investigations, the logical assumption was that immunofluorescence might be incorporated into an efficient system in which a specific organism associated with fecal pollution, such as S. faecalis, could be rapidly identified. Based on this assumption, the feasibility of fluorescent antibody techniques, using S. faecalis was investigated as a means of rapid determination of bacterial pollution in water. Although much progress has been achieved in the study of cytochemical reactions …

The chansonnier held by the Biblioteca Casanatense in Rome, designated Codex 2856 (0. V. 208), is a handsome volume containing 123 polyphonic compositions in the style of the Franco-Flemish School, circa 1450 to 1400. Although no text beyond the incipit is found in the manuscript, the value of the source is enhanced by the names of the composers of 106 of the compositions. Volume one focuses on the manuscript, giving a physical description of the manuscript, recounting the history of the manuscript, and includes discussion of selected composers and a concordance. Volume two contains the music of the chansonnier Biblioteca casanatense 2856.

In making this study it is important to search for ways to enhance and, if possible, make detection of MMO signals simpler in order that this technique for obtaining FS measurements may be extended to other materials. This attempt to improve measurement techniques has resulted in a significant discovery: the eddy-current techniques described in detail in a later section which should allow MMO to be observed and sensitively measured in many additional solids. The second major thrust of the study has been to use the newly discovered eddy-current technique in obtaining the first indisputable observation of MMO in zinc.

The problem of the study was a comparison of the relative effectiveness of two approaches to the teaching of engineering drafting.

The purpose of this study was to compare the effects of four micro-teaching environments on fourth-grade pupils' coping behavior and verbal response and to determine if one micro-teaching environment is more appropriate than another.

The primary purpose of this study was to analyze the capability and inclination of the aerospace and electronics industry contractors to abide by the general provisions of the Cost/Schedule Control Systems Criteria (C/SCSC).

The purpose of this investigation was (1) to isolate and purify glyoxalase I from the livers of normal DBA/lJ mice and the livers from mice bearing a lymphosarcoma tumor; and (2) to determine, at least with respect to glyoxalase I, if the tumor has an effect on the chemical properties or structure of macromolecules in an organ removed from tumor locale and not histologically affected by its presence.

The thesis of this study is that modern optimization theory is a natural extension of classical optimization theory. As such, modern optimization theory will be applied to administrative problems only after interpretive studies are made that provide (1) an explanation of the general theoretical development of the techniques of modern optimization theory, (2) computational algorithms for implementing the techniques of modern optimization theory, (3) detailed demonstrations of the computational aspects of each technique and its corresponding algorithm, and (4) an identification of the types of problems to which these techniques are applicable.

The purpose set for this study was to define tentative standards of achievement through the analysis of compositions written by fifth, eighth, and eleventh-grade students in terms of quantity and quality.

The specific purposes investigated were to ascertain the effect of training in interaction analysis upon the levels of 1. accurate empathy in teachers, 2. nonpossissive warmth in teachers, 3. genuineness in teachers, and 4. an analysis of the relationship between interaction analysis and the interpersonal behavior of the classroom teacher in view of its implications in teacher education.

The purpose of this investigation was to extend the study of possible differences between Negro and white boys on measures of physical fitness and to determine the relationship between certain variables and physical fitness for Negro and white boys.

It was proposed to study the cycloaddition of ketenes and carbodiimides in some detail. The first objective was to investigate the general applicability of the reaction as a tool for the synthetic organic chemist in the preparation of a new class of substituted β-lactams; i.e., imino-β-lactams. It was proposed for this part of the research problem to look for the intermediate, either directly or indirectly, by trapping experiments. It was further proposed to study substituent effects in the ketene and carbodiimide and also Investigate the effect of solvent polarity on the reaction rate. From these data, it was hoped that the mechanism of the cycloaddition reaction could be elucidated.

The purpose of this research has been to investigate the ability of subjects of three mental ability levels—normal, educable retardates, and trainable retardates—to recognize and identify familiar visual images projected in a manner assuring standard degrees of ambiguity of the projected images under the conditions of social satiation and non-satiation.

The purpose of this research was to compare the scores on the variables of ability, achievement, and adjustment in an effort to locate areas wherein the children who perceive and project verbally a high amount of violence are significantly different from children who perceive and project a low amount of violence.

The primary purpose of the study is twofold: first, to develop a set of criteria that can be used effectively to evaluate projects that will develop in students those skills and concepts emphasized in the goals and objectives of industrial arts; and second, to evaluate these projects by using evaluative criteria developed for that purpose. After the completion of the study, a convenient source book of projects for teachers will be compiled.

It was the purpose of this investigation to attempt to demonstrate if differences in eutrophic levels existed among selected areas of Garza-Little Elm, and to demonstrate the role that sediments play in affecting eutrophication.
