Original in the collection of Mr. Mires.)] Sinkers were not seen by us among archaeological finds in the Thompson River region but Mr. James Teit has informed the writer of their use there on both nets and lines, particularly on the former. Nets, excepting the bag net, were very little used in the Kamloops-Lytton region along the Thompson River and that may account for a scarcity of sinkers among archaeological finds. Nets were more extensively used on the Fraser River, but were very much used near large lakes and consequently one would expect to find sinkers in the vicinity of such places as Kamloops, Shushwap, Anderson, Seaton, Lillooet, Nicola, Kootenay and Arrow Lakes. Now, as the Shushwap generally made little bags of netting in which they put their sinkers to attach them to nets, this would greatly militate against the finding of grooved, notched or perforated sinkers in the Shushwap part of this region. They probably thought this method was more effective or took up less time than notching, grooving or perforating stones, and attaching lines to them. It is unknown which of these methods is the most primitive. Unworked pebbles, chosen for their special adaptation in shape, and others grooved or perforated were used in some parts of the interior of British Columbia for sinkers which were not enclosed in netting. Unworked pebbles attached to lines have been seen in use among the Thompson River Indians by Mr. Teit who sent a specimen of one to the Museum.[68] These were of various shapes, some of them being egg-shaped. A deeply notched oval pebble was found on the site of an old semi-subterranean winter house on the west side of Fraser River at the month of Churn Creek in the country of the Fraser River division of the Shushwap. The Thompson Indians said it had been intended for a war ax and accordingly one of them mounted it in a handle. It is now cat. No. 16-9073 in this Museum. Mr. Teit believes the stone to be too heavy for a war club of any kind and that possibly it may originally have been a sinker, although it is chipped more than necessary for the latter. In 1908, he saw a perforated sinker found near the outlet of Kootenay Lake, on the borders of the Lake division of the Colville tribe and the Flat-bow or Kootenay Lake branch of the Kootenay tribe. It was made of a smooth flat water-worn beach pebble 132 mm. long by 75 mm. wide and 25 mm. thick. The perforation was drilled from both sides near the slightly narrower end and a groove extended from it over the nearest end where it formed a notch somewhat deeper than the groove. Mr. Teit heard that several such
