20:11, etc. Pit
25.10.48 Dig below 10.20 & find a mixed layer of very unusual clays for Bamboula, green, red-brown, deep grey, etc. Keep samples. Digging a bit lower, we realize that this is bed rock: a heavy clay with brightly coloured green & dark brown strata, with chrome yellow spots. Dig away 30 cm. to be sure. This is most unusual, and should be analysed for metallic content; it may have some bearing on the copper industry in this area. Dig down west of the trial pit, and find a reasonably well preserved oven at 9.87. Photos '48 B 6.7 partly cleared
