Trenches taken across the hut circles did not yield much. In one a rubbing-stone of the split-pebble type was found, but I do not think that any other stones showed conclusive evidence of human use, or belonged to any recognised type. A trench taken across the space between the inner and outer defensive wall yielded a number of sling stones, especially under the outer wall. Some were found also in what may be called the guard hut, to the left of the main gate as one passes out Of these a few occurred iu dark mould at a depth of 1 ft. below the surface, but most were found above this level and amongst angular fragments. The presence of Caer Scion t. — these water-worn pebbles amongst the large quantities of angular, splintered rock is, I take it, fairly conclusive evidence of human importation. One hut just within the western end of the camp proved to have its floor largely covered with flat stones. These were of irregular shapes and sizes, but were on one level, while at the northern side of the hut several large ones were rather carefully fitted together. These slabs did not show any signs of use as a hearth. The stones were all carefully replaced, and of the large ones measurements were taken and a drawing made.
