This investigation has determined the presence of biological nitrogen fixation in two reservoirs in the southwestern United States: Lake Arlington and Lake Ray Hubbard. Subsequent tests have gathered baseline data on the effects of various biological, chemical, and physical parameters on in situ nitrogen fixation in these reservoirs. Of specific importance is the relationship between nitrogen fixation arid occasional blooms of blue-green algae which produce such problems as testes and odors in these water-supply impoundments.

The problem with which this investigation is concerned is that of determining the procedures and methods elementary school principals in Texas utilized to implement the state-supported kindergarten program. A questionnaire was developed and content validity established by five authorities in the field of early childhood education.

The first is to describe the most frequently used procedures to implement the state-supported kindergarten program. The second is to identify those procedures used that are not educationally beneficial to young children to assist in statewide planning.
