In 1964-5 K.D. Banerjee *et al.* (*IAR 1964-5*, p. 20) laid four trenches 1 km away from Attirambakkam along the right bank of the Budida-Manu-Vanka on the high cliffs of approximately 50 m contour, showing the following stratification: (1) Sriperumbudur shale with a clayey top and with embedded remarkably fresh handaxes and cleavers, it being uncertain whether the horizon of this industry was simply on the surface of the shale or was an overlying deposit now washed away; (2) detrital laterite, containing the post-Acheulian flake industry, the tool types including points, scrapers and longish blade flakes; (3) sterile brownish silt; and (4) top surface yielding microliths [4.5]. The work shows that the current view that the laterite gravel is the Acheulian horizon is incorrect and that the silt is not the horizon of the post-Acheulian flake industry.
