The interior was about in diameter, the floor had been leveled, then covered with yellow clay over which a pavement of rough slabs and river pebbles had been laid. On the pavement was an accumulation of deposits, in some places deep, in and on which the relics were found... coins, stone objects, a glass bead, 1st- or 2nd-century Samian bowl fragments, burnt bones and iron objects. A sandstone cauldron was found near the centre of the interior, close by was a fireplace of slabs set on edge; this, he states, was possibly used to heat the water in the cauldron. An irregular lump of sandstone was also found, bearing two chiseled cup marks one on each side, almost opposite each other. During his excavations he found four silver Roman coins, all denarii, two of Antoninus Pius and one each of Vespasian and Hadrian, all of which came from parts of an upper black layer of occupation. Smith's collection of this material was donated to the National Museum of Antiquities of Scotland in 1981.
