(le Liiguna] ARCHEOLOGY, YAKUT AT BAY AREA, ALASKA 147 



Of less definite shape and thus resembling some of the small slate 

 blades (cf. fig. 14, d, e), are three specimens of split rib (pi. 15, l~n), 

 5.5 to over (6.7) cm. long, with rather dull edges and sharp points. 

 These are also probably arrowheads. One is from Old Town III, 

 and an additional fragment is from Old Town II. 



There are four additional blades of solid bone (pi. 15, r-t), about 

 7 by 1 cm., which may have been for arrows, or possibly for small 

 knives, since they are not very symmetrical. AU are from Old Town 

 II. 



Also from the same level is a longer and more slender blade (fig. 

 17, a), 12.7 cm. long, which is almost certainly an arrowhead, since 

 its thin, flattened, squared-ofF butt and sharp point resemble in style 

 those on some of the barbed bone arrowheads. Two fragments too 

 smaU to identify with certainty but which suggest similar points are 

 from Old Town II, and one from Old Town III, 



There are six flat blades or points of bird bone, with duU edges and 

 sharp points (pi. 15, o-q). AU are under 7 cm. in length, and, with 

 one exception which is from Old Town II, are from Old Town III. 

 They may have been arrowheads, although identification is uncertain. 



There are other points of bij-d bone (pi. 15, g-j), anunal rib, and 

 other animal bones, which may also have been arrowheads, barbs 

 for fishhooks, teeth for fish rakes, or parts of other implements. 

 Identification of function is in most cases impossible. (See below.) 



Unbarbed bone arrowheads are not uncommon on the Northwest 

 Coast and in southwestern Alaska, although the lack of pronounced 

 characteristics makes comparisons difficult. Chugach specimens 

 tended to have flattened points like blades and were perhaps most 

 similar to some of the Old Town examples. Cylindrical pinlike 

 arrowheads were common on Kachemak Bay and Kodiak (de Laguna, 

 1956, p. 179; Heizer, 1956, pi. 54, a-f). Our knowledge of Northwest 

 Coast archeology is insufficient to make detailed comparisons, but 

 we may note that many bone points from Cattle Point in the Gulf 

 of Georgia, some of which were probably arrowheads, approach these 

 northern forms (King, 1950, fig. 13, 15-23, p. 45). Large unbarbed 

 bone points are reported ethnologically from the Tlingit to the 

 northern Kwakiutl and Nootka (Drucker, 1950, Trait 499). Angoon 

 informants described such arrowheads, usuaUy about 10 cm. long, 

 or even 15 cm. long, for bear. Although unbarbed, they were detach- 

 able (de Laguna, 1960, p. 114). The Yakutat specimens, though 

 shorter, probably belong to the same tradition. 



BONE POINTS, SHAFTS, AND COPPER PINS 



In addition to the specimens described as unbarbed bone arrow- 

 heads, there are a number of miscellaneous bone points, some of which
