In view of the foregoing factors, it is concluded that Mounds B, C, and D at the Harroun Site were purposely erected over the ruins of the burned houses. It appears certain that the four houses at the Harroun Site were typical Caddoan houses. Perhaps they were of the traditional “beehive” shape, or possibly they had wattle-and-daub walls and thatched roofs like those photographed by Soule about 1870 and pictured in Webb (1940: Pl. 8, 1). Historical descriptions and sketches of Caddoan houses indicate that they did not usually have extended, covered entranceways as do a majority of the prehistoric houses that have been excavated in the Caddoan Area. This suggests that the extended entranceway was used at a relatively early period but was abandoned prior to the 17th century. However, Caddoan houses of the early historic period will have to be excavated before a definite statement can be made in this regard. Ceramics at the Harroun Site consisted mainly of brushed, incised, engraved, and appliquéd styles, including types Ripley Engraved, Taylor Engraved, Bullard Brushed, Pease Brushed-Incised, and Maydelle Incised. One sherd of Crockett Curvilinear Incised was also found, and two other sherds are similar to the types Coles Creek Incised (or Chase Incised) and Beldeau Incised. Ripley, Taylor, Bullard, and Maydelle are all indigenous types of the Titus Focus (Suhm _et al._, 1954: 192), Ripley in particular being considered diagnostic of the focus. Beldeau Incised and Coles Creek Incised are Lower Mississippi types and they are surely intrusive in the site. Both were buried between 2.5 and 4.0 feet deep in the floodplain (but at different locations) and they may pre-date the mounds. The sherd of Crockett Curvilinear Incised came from a disturbed area at Mound B, but four sherds from a Gibson Aspect engraved bottle are anomalies that are apparently associated with the mound period at Harroun. The most common type in the small sample of arrow points is Perdiz, generally considered to equate in time (in East Texas) with the Fulton Aspect, but usually thought of as a trait of the Frankston Focus—not the Titus Focus. Dart point types Cary, Ellis, and Wells—all found at the Harroun Site—are widely distributed in East Texas, and any or all of these types could be affiliates of the Titus Focus or related complexes, although such associations have not been previously demonstrated. The few miscellaneous stone artifacts are relatively non-distinctive in form.
