The general character of the group of relics obtained from these structures is that of the Iron Age, with indications of a period subsequent to the Roman conquest. The same character and the same indications are presented by the group of relics obtained from the Crannogs of Ayrshire, which have been so carefully investigated by Dr. Munro.[96] The Lochlee Crannog, near Tarbolton, yielded a very large collection of objects in the various materials of stone, bone, wood, bronze or brass, iron, glass, and jet or cannel coal. But with the single exception of a polished stone celt, the types of the Stone and Bronze Ages are entirely absent from the group. The same thing is true of the collections obtained from the Crannog at Lochspouts near Maybole, and the Buston Crannog near Kilmaurs. But in these Crannog collections there are certain groups of objects which are closely akin to those found in Brochs. These are the hammer-stones, oblong water-worn pebbles wasted at the ends by use, spindle-whorls and querns, the round polished discs of stone, the peculiarly-shaped bone pins, needles, and borers, the double-edged bone combs, the deer-horn implements, the bronze brooches, rings, and pins, and the spiral finger-rings. There are also certain objects in these collections which present features of form and ornamentation clearly of the early Celtic types, such as a bridle-bit from Lochlee (of the same form as that shown in Fig. 101), a block of ash-wood from the same Crannog with Celtic patterns cut in both sides, and a bronze mounting from Lochspouts, which is characteristically Celtic in style. On the other hand, there are certain objects which, like the harp-shaped fibulæ and the lustrous red ware (commonly called Samian), are indicative of post-Roman times. The bulk of the relics from the Crannogs being thus of Iron Age types with indications of post-Roman time, and with a striking general affinity to the group of relics obtained from the Brochs, the place of these lake-Dwellings in the general series may be considered as sufficiently established.[97] ----- Footnote 96: Since these Lectures were delivered an exhaustive treatise on _The Lake-Dwellings of Scotland_, by Dr. Robert Munro, of Kilmarnock, has been issued. In this copiously illustrated work Dr. Munro has described the Crannogs in Ayrshire recently excavated under his personal superintendence, and systematised the whole subject in a manner that leaves nothing to be desired.
