Among the larger implements of this period the most remarkable and varied are the Stone Hammers and Axes. They are of common occurrence, and present a variety of forms, evidently designed to adapt them to a considerable diversity of purposes. They are therefore available as evidence in estimating the degree of inventive talent manifested in the primitive state of society in which they were produced, showing as they do the intelligent savage coping with the untractable materials with which he had to deal, and supplying many deficiencies by his own ingenuity and skill. With these, as with the elf-bolts of the same period, we find in the reminiscences of early superstition the evidence of their frequent occurrence long after all traces of their origin and uses had been obliterated by the universal substitution of metallic implements. As we find the little flint arrow-head associated with Scottish _folk-lore_ as the Elfin's bolt, so the stone hammer of the same period was adapted to the creed of the middle ages. The name by which it was popularly known in Scotland almost till the close of last century was that of the Purgatory Hammer. Found as it frequently was within the cist and beside the mouldering bones of its old Pagan possessor, the simple discoverer could devise no likelier use for it than that it was laid there for its owner to bear with him "up the trinal steps," and with it thunder at the gates of purgatory till the heavenly janitor appeared, that he might "ask, With humble heart, that he unbar the bolt."[170] The stone hammer is frequently found in the older cists. In 1832 a farm-servant while ploughing a field on the farm of Downby, in Orkney, struck his ploughshare on a stone which proved to be the cover of a cist of the usual contracted dimensions, in which lay a skeleton that seemed to have been interred in a sitting posture. At the right hand lay a highly polished mallet-head of gneiss, beautifully marked with dark and light streaks.[171] [Illustration: Stone Hammers and Axes.] The examples figured here furnish a few of the most characteristic varieties of Scottish hammers that have been preserved. They by no means equal in number those found in Denmark, Sweden, and Norway. But only a very partial and extremely superficial investigation of such relics has yet been made, and we possess no national collection in Scotland, similar to that of the Christiansborg Palace of Copenhagen, to which the whole available financial and legal machinery of the kingdom is employed in gathering the primitive national antiquities so soon as they are discovered. The Old and New Statistical Accounts abound with notices of opened tumuli and cairns, and of their valuable archæological contents; but unfortunately in nearly every case these are either conveniently ascribed to Romans and Danes, or mentioned so vaguely that no use can be made of them as illustrations of the period to which they belong.
