Hundreds of ovate pellets of clay, generally of the size of a pigeon's egg, burnt and unburnt, have been found on the site of the lake-village of Glastonbury, and are regarded as sling-bolts, or perhaps fire-bolts. Similar clay pellets have been dug up on the site of Ardoch Camp associated with Roman pottery and other Roman remains.

Their geographical distribution seems to me to have an ethnographical significance. Thus of 111 specimens dealt with, no fewer than 56 were traced to Aberdeenshire, and the rest to the eastern districts of Scotland, chiefly north of the Firth of Forth—the exceptions being three from Lanarkshire, two from the counties of Dumfries, Argyll and Wigtown, one from Islay, and one from Ireland.
