SINKERS. 179 



fornia Academy of Sciences, at San Francisco. Tlie object, to judge from its 

 imitation, is well worked. The upper end shows a deep groove, running verti- 

 cally from one aperture of the bi-conical hole to the other. I cannot state of 

 what material the specimen is made, and from what special locality in Cali- 

 fornia it is derived. My inquiries led to no definite result. A cast of another 

 Californian sinker of the same shape was sent by JNIr. R. E. C. Stearns to the 

 National Museum (No. 30110). The original, consisting of dark slate, was 

 found in Solano County. 



Fig. 320. — This specimen is made of a flattish pebble of fine-grained sand- 

 stone, to some extent modified by grinding. A well-ground horizontal groove 

 passes through the apertures of the cylindrical perforation. The object has the 

 appearance of a sinker ; but, nevertheless, may have been designed for another 

 use. From Cleveland, Ohio. Presented bv General J. T. Wilder.

Fig. 321, — A well-made Eskimo sinker of greenish porphyr^^ having at 

 both ends perforations whicli still hold cords of thong and sinew-remnants of 

 the line and of a strij) to which the hook w^as attached. The perforations run in 

 opposite directions. Obtained on XJkivok or King Island, Alaska, by Mr. L. M. 

 Tui'ner. 



In concluding my account of North American stone sinkers, I present on 

 page 180 two illustrations of such articles, which should have been noticed in 

 their proper connection with others of similar character. The figures, however, 

 show the objects exceptionally in natural size, being printed from blocks not 

 specially prepared for this work, but already used in an official report.* The
