Fig. 15.—Interior of the passage grave at Uby. The spaces between the large stones filled with pebbles. The roof is formed by two large stones which have been cut from a large block.

The length of the stone coffin was generally from 8 to 13½ feet, width from 3 to 5 feet, height from 2½ to 5 feet. A few, especially in Vestergötland, are from 19½ to 31 feet in length, one of the longest graves of this kind in Sweden being one on Stora Lundskulla, in Vestergötland, with a length of 34 feet, and width of 8 feet. Nearly all other stone coffins found are, like the gallery graves, without a stone at the southern end. This cannot be accidental.

Besides the stone coffin above described, several have been found covered with a mound. The chambers are generally formed of upright flat stones, and roofed also with stones. They are generally smaller than the stone coffins, being from 6 to 10 feet long, and closed on all four sides; sometimes, however, there is found in the southern end an opening as previously mentioned.

POTTERY.

Fig. 16.—Clay urn—Stone age—⅓ real size. In passage grave, Stege, island of Möen, Baltic, found with remains of some skeletons. Two stone axes, a flint saw, 2 arrow-points, 3 spear-heads, fragments of clay vessels with covers, pieces of a wooden tub, 2 awls of bone, a chisel of bone, 3 flint wedges, 2 flat scrapers of flint, and 17 amber beads for necklace were also found in the grave. The same mound was afterwards used for burials belonging to the bronze age, with cinerary urns with burned bones, on the top of which was a double-edged bronze knife, &c.

The same mound was afterwards used for burial belonging to the bronze age; near the top, and entirely separate from the burial-chambers, there was discovered a very small stone coffin containing an urn with burnt bones, and on these lay a fine double-edged knife, a knife, and a pair of pincers, all of bronze.
