Cores
c7.s17.t1.1
12 No. 11, KDL. A large amorphous core showing two techniques. On one side two or three flakes have been removed by direct percussion on either side with a stone hammer, leaving deep flake scars and a jagged edge. Almost on the opposite face, there are two shallow parallel flake scars, obviously by pressure flaking; while on the adjoining face there are series of small shallow scars, mostly due to step-flaking. Where these two flaked surfaces meet, a borer point has resulted, perhaps accidently. The material is basalt and is stained dark black and brown. Found *in situ* in the lowest cemented gravel in Nala 1 on 9-10-1960.
c7.s17.t1.2
13 No. 7, KDL. A small plano-convex core. One large flake and a small one have been removed from either side. Light yellow. Found *in situ* in the lower gravel on 8-12-1960.
c7.s17.t1.3
16 N. 6, KDL. Roughly rectangular core from which 7 to 8 flakes have been removed by direct percussion method. The flaking is from the edge. Since the material is fine glassy, [Figure: LEGEND TIDAL SWAMPS ALLUVIUM RHYOLITE TRACHYTE AND STRATIFIED ASHES INTERTRAPPEANS BRECCIA, AGGLOMERATE OCEANITE, ANKARAMITE, MONCHIQUITE BASALT

obsidian-like basalt, the scars are deep. *In situ* lower gravel, Nala 1. Found on 9-12-1960.
c7.s17.t1.29
