My last report presented a year ago concluded with an account of the third excavation of the ditch outside the circular earthwork. A fourth excavation in continuation of the third was begun immediately afterwards and carried 26 ft. to the west. It was made 2 ft. wider, as the ditch here appeared to have been wider and deeper, but except for this there was no appreciable difference from former sections. The upper soil had been much disturbed by rabbits or persons digging them out, the burrows being occasionally found to be 4 ft. deep. The upper layer of humus, and the rubble layer beneath it, contained chips of the building of Stonehenge to the number of 570, but none was found lower than the junction with the silt. With the chips were four small worn pieces of Bronze Age pottery, 10 of the Roman Period, a small quartzite maul, about 60 animal bone fragments, and the greater part of a human ulna bone.
