the heap of stones, to such an extent that the floor of the chamber is some 

 2 feet below the present average level of the base of the mound. The 

 entrance faces north-west by north (compass bearings 328'). It is a small 

 hole, confined between a lintel and a threshold very close together ; but it 

 gives access to a chamber of considerable size, which is by far the best piece 

 of construction in the whole series. A plan and sections of the earn are given in 

 Plate XXII, and of the chamber on Plate XX. "WeU-selected standing stones 

 of a maximum height of 6 feet support a system of lintels and cross-beams of 

 stone, which, rising by oversading courses, form a chamber very similar to 

 Brugh na Boione both in plan and construction. The roofing-slabs, as in 

 Cam F, slope downwards to the outside. The main chamber is more or less 

 circular, and three smaU cells, of lesser heights and separated by high siUs 

 from the main chamber, give a cruciform shape to the plan of the structure. 

 These ceUs are the receptacles for the interments. Each is floored with a 

 large flagstone, and a simdar flagstone occupies the floor of the central 

 chamber. These flagstones were raised, but nothing was found underneath 

 them. Plate XIV, fig. 2, illustrates the construction of the inside of the 

 chamber ; but it is impossible to secure a pihotograph that does justice to the 

 building, which, though it may seem an exaggeration to say so, is beyond all 

 praise as a veritable work of art. The builders aimed not merely at a 

 building which should remain standing : they evidently took a pride in 

 erecting a neat and symmetrical chamber. In one or two cases we suspected 

 that a single block had been split in two, in order to secure as nearly as 

 possible identical stones for corresponding positions on opposite sides of the 

 chamber. The fourth standing stone on the right hand side of the entrance 

 did not reach the roof, and inserting the hand behind it we found that there 

 was here a sort of shelf or pocket in the wall, which contaiued the bones of 

 chUdren. Its outline is indicated by dotted lines in the plan. The space 

 was just under the roofing-slab, and measured 2 feet 6 inches parallel to the 

 chamber by 2 feet at right angles to it. The floor of this " shelf " is on a 

 level 4 feet 4 inches above the floor of the main chamber, and the height of 

 the clear space is about 1 foot 9 inches. A similar pocket was also found 

 behind two of the stones in the left-hand recess. In each of the rimer comers 

 of the right-hand recess there is a block of stone about 8 inches square and 

 1 foot 3 inches high, set on end. On the western side of this cam, half buried 

 in the turf, a slab is lying which may possibly have been intended for the 

 construction but left over. It is 1 foot 3 inches thick, 7 feet 3 inches long, 

 3 feet broad at one end, 5 feet broad at the other. 



BL — The entrance of this structure was foimd open, unlike all the other 

 perfect cams of the series, and had evidently been open for a very consider-
