This study is another phase of the overall research program designed to furnish basic information for the management of East Texas lakes and has as its specific purpose the determination of the age and growth characteristics of two valuable species on these waters. The species to be considered are the black crappie, Pomoxis nigro-maculatus (Le Sueur) and the white crappie, Pomoxis annularis Rafinesque. Both species are highly regarded as food fish and have for many years offered recreational outlets for Texas fishermen.

The present investigation deals with the study of non-glandular epidermal hairs from the leaves of two hundred representative dicotyledons of forty-eight families in the Central North Texas area. Special attention has been given to the Compositae and Leguminosae in an effort to find a possible correlation between epidermal hair morphology and the taxonomic position of the plants concerned.

This investigation has for its aim the confirmation of the correlation between soil moisture and the microflora of soils, and a lesser relation between the soil temperature and the microflora. The soils used in this study are typical clay soils of Denton County, Texas. The samples were taken from virgin pasture lands and analyses made monthly or semimonthly. The wide seasonal variation of temperature and rainfall afford a good opportunity for this study.

This study is based upon information taken from stomach analysis of 302 black crappie and 561 white crappie; the following data will be presented: 1. Food of adults and fingerlings; 2. Diet variation in relation to food availability; 3. Seasonal variation of feeding habits; 4. Diet variation in relation to size of crappie. Collections were made from ten lakes located in North, East, Central, and South Texas.

This paper consists of a study of the soils and vegetation found in Rockwall County, Texas. This county is located in the northeastern part of the state. Rockwall County lies in the northeastern part of the Black Waxy Belt of the Coastal Plains province.

This paper deals with certain phases of phototropic properties of two exceptional plants, the pertinent behavior of each being decidedly individualistic and in remarkable contrast to that of herbaceous plants in general. The prickly lettuce, Lactuca ludoviciana (Nutt.) DC. and the rosinweed, Silphium laciniatum L., two common Denton County, Texas, plants, have been selected for this study.

This study had for its aim the collection, identification, and listing of the spermatophytes growing upon the Austin Chalk formation of Collin County, Texas.

This investigation has attempted to show that soil and water conservation practices do increase the amount of soil moisture in five of Denton County, Texas soils: Denton clay, Durant clay, San Saba clay, Kirvin fine sandy loam, and Tabor fine sandy loam.

The purpose of this study is to determine the status of elementary science curricula in the different state universities and the leading teachers colleges in the United States.

The purpose of this investigation is to compare the dissolved and suspended organic material in Lake Dallas to that coming into the lake through Pecan Creek.

A bacterial analysis of the water from thirty-six sources of consumption by the white population of Trinidad, Henderson County, Texas, was made to determine the potability of each of these in regard to infection from typhoid or related organisms.

This study is one phase of a research program designed to provide basic information which can be used in the management of East Texas Lakes.

This investigation was conducted in order to show that insanitary conditions may exist in the swimming pool at North Texas State Teachers College provided the proper precautions are not taken; and, in contrast that this pool can be sanitary and entirely safe when operated and used according to the necessary sanitary specifications.

The problem consisted of thoroughly exploring Tarrant County, Texas, in an attempt to collect and study critically as many species of Spermatophytes as possible. In addition a thorough examination was made of herbarium specimens assembled from the region by other botanists.

This paper deals with the distributional outgrowths of Prosopis chilensis (Molina) Stuntz, the common mesquite, in Denton County, Texas.

This investigation has for its aim the determination, in a measure, of the degree of personal sanitation existent among students at North Texas State Teachers College, Denton, Texas.
