Annual journal of the Texas Archeological Society documenting research and findings of members as well as activities of the organization.

From Abstract: "Primary interest was placed on the scale formation problem. Significant improvements were made in the process and described in this report. Maintenance requirements were unusually high during the year, primarily as a result of cumulative corrosion damage over the last three years. The most significant damage was in the circulating pumps, the heat exchangers and feed piping. These and other failures are described."
