One type, in which the upper stone is funnel-shaped, with radiating grooves from the centre perforation, is believed to be the portable hand mill of the Roman soldier. It is engraved as such in Stuart's Caledonia Romana, _Plate_ XIII.; and the only one of the same kind in the Scottish Museum seems to corroborate this, in so far as it was found to the south-west of Camelon, on the line of the great wall of Antoninus Pius. It exhibits, as might be expected, more regularity and method in its construction, and is surrounded with an iron band, now greatly corroded, with a loop or ear, to which the handle was attached for turning it. We shall not, probably, greatly err in assuming as one of the earliest types of the Scottish hand-mill, the rudely fashioned oaken querne already referred to, which was dug up from a depth of nearly five feet in the Blair-Drummond Moss. It is simply the section of an oak tree, measuring nineteen inches in height by fourteen inches in diameter. The centre has been hollowed out to a depth of about a foot, so as to form a rude oaken mortar; and in this, with the help of a stone or wooden pestle, its primitive possessor was doubtless wont to bruise and pound the grain preparatory to its conversion into food. The circumstances under which the Blair-Drummond querne was found, when compared with the other discoveries in the same locality, scarcely permit us to escape the inference that in it we possess a domestic utensil contemporary with the ancient canoes of the Forth and Clyde, if not with the stranded whales, and the rude harpoons of the carse land from which it was disinterred.
