23/7/98 Photographed oven F87 and drew section. WM decided would sample part of oven where ash deposit [2859] on floor, rather than sample on section through mid-line of oven. Removed remainder of [2848] and [2851] on S. side of oven. Can see line of collapse/edge of in-situ material clearly on S. side now.Entered By: Richard Turnbull
