236 having somewhat acorn-shaped ends, was found by the late Hon. W. O. Stanley, at Old Geir, Anglesea. Others from Anglesea, one of them ornamented, have been figured. They were originally regarded as hammer-stones, but such as I have examined are made of a softer stone than those usually employed for hammers, and they are not battered or worn at the ends. It is, therefore, probable that they were used as sinkers for nets or lines, for which purpose they are well adapted, the groove being deep enough to protect small cord around it from wear by friction. They seem also usually to occur in the neighbourhood either of lakes, rivers, or the sea. A water-worn nodule of sandstone, 5 inches long, with a deep groove round it, and described as probably a sinker for a net or line, was found in Aberdeenshire, and is in the National Museum at Edinburgh; and I have one of soft grit, and about the same length, given me by Mr. E. D. Darbishire, F.G.S., and found by him near Nantlle, Carnarvonshire.

The Fishing Indians of Vancouver's Island go out trolling for salmon in a fast canoe, towing behind them a long line made of tough seaweed, to which is attached, by slips of deer hide, an oval piece of granite perfectly smooth, and the size and shape of a goose's egg. It acts as a sinker, and is said to spin the bait. A net-sinker, formed of a pebble slightly notched or grooved, is among the antiquities from
