AX EXPLORATION OF TKEGAEK ROUNDS. 77 



invisible from it. The covered way from Tregaer Eoiinds to 

 the valley below points in the direction of Pengenna, but 

 whether there is an actual connection between the two places the 

 authors have been unable to ascertain. Whether these two 

 camps were contemporary we are not yet in a position to say. 



An adit has been driven from the ditch under the rampart 

 nearty opposite to, and in the direction of, 4 on plan. It has a 

 length of fifty-one feet, is about five feet wide and six feet high. 

 The soil, &c., from this excavation have been placed on a heap at 

 X (see plan). Although modern, none of the inhabitants could 

 explain why sixch an excavation was made. 8ome thought that 

 it was a mining adit made many years since, when the neigh- 

 bourhood was worked for antimony, and others thought it was a 

 potato kieve or a hiding place for smiiggled goods. 



It is undoixbtedly modern and had nothing to do with the 

 construction of the camp. It is curious that the excavators took 

 the trouble to carry the material and deposit it at x when they 

 might easily have thrown it out in the ditch on each side of the 

 entrance to the adit. This entrance is closely masked with 

 bushes and is not easily found by a casual visitor. The explor- 

 ation commenced on May 21st, 1902, and was continued on the 

 22nd, 23rd, 24th, 26th, 27th, 28th and .-iOth. Six men were 

 employed. Trenches were dug measuring 827 feet in length and 

 were carried down in some cases to 6 feet. The breadth of 

 these varied from 4 to 10 feet. 



In every case but one the excavations were continued down 

 to the undisturbed sub-soil or "raze" as it is locally called. 

 The inside of the outer ring or rampart was hist examined and 

 eighteen trenches were diig close to the foot of, and following 

 the trend of, the embankment, at intervals, around the whole 

 circumference. 



Short trenches were also driven into the rampart and others 

 again were extended into the enclosed area. Experience has 

 demonsti ated that the hut sites and camping places in these early 

 strongholds are usimlly to be found close up under the lee of the 

 ramparts, and the efforts of the exj^lorers were concentrated in 

 this direction. The cultivated land enclosed within the boun- 

 daries of the camp was disturbed as little as possible.
