It will be noted that the thin stone clubs found here have no mid-rib. Clubs made of stone, whale's bone or wood with such mid-ribs are unknown from the coast but are found with median decoration in place of a mid-rib,[236] those of whale's bone being common and a thin club made of copper with a median decoration was found at Spuzzum in the interior of Southern British Columbia.[237] [236] Smith (b), Figs. 173a, b; 169a; 165a, c-g; 166a, b, d-g; 167a-d; 168a, c, d; 169f and 170a. [237] _Ibid._, Fig. 172d. _'Slave-killers.'_ A 'slave-killer' or club, made of friable stone shown in Fig. 67, was found on the surface of Union Gap, below Old Yakima. It is in the collection of Mr. Janeck. The object has a blade which sets out from the handle and resembles in shape the typical 'slave-killer' in that it is lozenge-shaped in cross section with bulging sides and rounded angles. The handle is oval or nearly circular in cross section, and slightly larger at the top where there is no knob or perforation as in the typical club of this type.[238] The object is 377 mm. long, 63 mm. wide, and 41 mm. thick.[239] The club or 'slave-killer' made of stone, shown in Fig. 68, was found at Lake Chelan, and is 280 mm. long. It is owned by Mr. C. G. Ridout of Chelan, Chelan County. The handle terminates in a knob, which resembles the form of an animal head. This knob is somewhat heart-shaped, the two lobes possibly representing ears, and the lower tip projects beyond the handle of the object. One side, the larger surface, stands at about 45 degrees to the axis of the club and is bisected by a deep incision, on each side of which are two circles, which probably represent eyes. On either edge of this knob are thirteen incisions. The handle which is nearly circular in cross section, bears four vertical rows of horizontally arranged incisions and expands suddenly edgewise to form the blade which, however, on its upper and lower surfaces is practically continuous with the handle. The blade is nearly circular in cross section and tapers gradually to a rather blunt point. The object is probably a ceremonial implement. [238] _Ibid._, Figs. 175, 176 and 177e.
