The entire number of Runic characters may be about 935, exclusive of scribbles and many doubtful marks. The monograms and bind-runes, or connected consonants, are considered as forming one letter. There are also some marks which may have been intended to represent a horse and an otter with a fish in its mouth; also, a winged dragon and a worm knot, which last has much the appearance of one of the great Saurians. The two hind legs are very plainly defined. BARROWS AT BOOKAN. This barrow is in the parish of Sandwick, but so near to Stennes that it may have been regarded as connected with the great circle. It is on the property of Mr. Watt of Skail, in the West Mainland. It was opened on the 6th of July, and proved to be a collection of kists or graves. At the north end of the central kist, a flint lance head, and several fragments of clay vessels or urns, were found, together with a lump of heavy metal, supposed to be Manganese, but no bones. In some of the other kists were human remains in a very decayed state, two jaw bones being the most perfect. These were much distorted. Mr. Petrie gives me the following measurements:--The Barrow is about 44 feet in diameter, and about 6 feet high. About 11 feet within the outer margin of the base of the barrow is a circular wall or facing about 1 foot high. From the south side of this wall a low passage, 6 feet 3 inches long, 21 inches in height, and the same in width, leads to a chamber or kist 7 feet long and 4-1/2 wide. At the north end of this there was another kist 4 feet 8 inches long, and 3 feet wide. On the east side there was one 4 feet 8 inches long, and 2 feet 9 inches wide; and on the west side two kists, both of which were of the same length as that on the east side, and both were 3 feet in width. They were all about 2 feet 8 inches deep. The foundation of the surrounding wall or facing was considerably above the level of the floors of the kists. LARGE BARROW CONTAINING GRAVES.
