This paper presents a major portion of the existing data concerning the Weeden Island complex of the Florida Gulf Coast. The most important sources of these data are the writings of the late Clarence B. Moore which deal with the results of several years of investigation of northwest and west Florida and adjacent regions. In the course of these investigations, Moore surveyed and excavated well over one hundred sites along this coast. Sources of secondary importance are various smaller exploration reports of S. T. Walker, F. H. Cushing, J. W. Fewkes, M. W. Stirling, and the present writer. In addition, available but unpublished notes and collections on Florida and reports dealing with geographically and culturally related areas of the Southeast were consulted.

San Vicente Lake is being formed by a dam across San Vicente Creek four miles north of the village of Lakeside, California. The dam is being constructed by the Water Department of the City of San Diego as a unit of its broad plan to develop the water resources of the adjacent Coast Range. The waters of the lake, which are now rising rapidly, cover a very beautiful valley. The surrounding mountains, covered with massive granite boulders, create a picturesque setting.

Although a reliable relative chronology, based chiefly on the sequence of pottery types, is rapidly being built up for the Andean area, no method has so far been devised for turning the relative dates into absolute ones. As far as we know at present, no permanent method of dating, comparable to the Maya Long Count or even to the Mexican fifty-two-year cycle, was in use in any part of South America, and no one has yet investigated the possibility of building up a tree-ring sequence, even in the drier regions of Peru. Furthermore, the distances that separate the Andean area from the Maya area have so far prevented any correlation of the early pottery types of the two areas, so that we cannot even estimate the age of Peruvian remains in terms of the insecurely correlated Maya calendar.

A group of small stone enclosures, supposed by some to be of natural origin and by others to be the works of man, lies on a rocky travertine-encrtfsted talus slope at the base of the Santa Rosa Mountains on the west side of the Coachella Valley in Riverside County, California. These phenomena are known locally as the "Ancient Fish Traps." They occupy a series of rocky terraces some 90 feet below the maximum high-water shore line of Ancient Lake Cahuilla (called by some Blake Sea), whose basin is now partly occupied by the Salton Sea. The “traps” consist of 85 to 100 bowl-like depressions composed of a travertine-encrusted granite talus debris. They are arranged in three rows, each of which follows the exact contour of one of the old recessional terraces of the lake (Pl. XIX).

A recent discovery in west-central Illinois seems sufficiently interesting and important to warrant this initial descriptive report. Six small pottery figurines were found with a compound burial in Mound 8 of the Knight Mound Group. Five of these human effigies, apparently fashioned to represent the prehistoric people culturally responsible for these mounds, not only display the remarkably smooth, stylistic skill of the culture and artisan producing them, but are modeled and painted to show costumes and styles in personal ornamentation wjth sufficient detail to make an important contribution to our knowledge of the producers’ material culture. The sixth figurine is extremely simple and devoid of detail, and is not painted.

In the summer of 1935 it was realized that a large group of sites just to the east of Flagstaff, between the San Francisco Peaks and the Little Colorado River in northcentral Arizona, were in several respects unique. The presence in this northern area of ball court structures similar to those recognized in southern Arizona by Haury and others was the most outstanding single feature. Subsequently, more detailed research revealed additional southern, or Hohokam-like characters in these sites, and a program of several years of extensive excavation and research was undertaken.

For an observer within the “tropics,” the day-count for a sun calendar is easily determined to the nearest day on four occasions: on the two equinox days, which are the same for all cities, and on the two zenith passages of the sun, which depend upon the observer's latitude. Sunset observations alone, contrary to a tacitly accepted dictum, determine the precise day of equinox, and the average 365¼-day length of the “tropical year,” if the record is continued over several years.
