Five of them have lightly incised decorations, usually on the con- 

 cave side of the rib. On one, the incisions consist of random diamond- 

 shaped incisions along the midline ; on another, the design is a wavy 

 line with angular crests and troughs. Random crosshatching and X 

 marks occur on two of them. Twelve shallow notches are cut into 

 the edge of one of the latter pieces (fig. 22, <?). The fifth incised 

 wrench has two incised X marks on one edge. 



Knife handle (1 specimen) : 



A piece of large rib, 137 mm. long, is cut into rectangular form 

 and smoothly polished. There is a small slot at one end, 60 mm. long 

 and 13 mm. deep, made by removing the cancellous tissue. A V-shaped 

 notch is cut into the handle behind this slot, and 15 mm. from this 

 notch is a smaller one (fig. 20, &). A similar specimen, of wood (fig. 

 20, <?), is described under the heading, "Perishable Remains." 



Fishhooks (2 specimens) : 



These implements are made from segments of mammal long bones. 

 On one of them, 40 mm. long and 16 mm. wide, the sharp point forms 

 an angle of about 40 degrees from the shank. The end of the shank is 

 notched to assure a firm attachment to the line (fig. 23, d). A sec- 

 ond object, superficially resembling a fishhook, probably had another 

 function. This object, 60 mm. long and 20 mm. wide, has a rounded 

 "point," and the end of the shank shows no modification for attaching 

 aline (fig. 23, e). 



Tubes (5 specimens) : 



Both ends of two eagle wing bones are cut, but they are not smoothed 

 and the cancellous tissue is intact. They may represent a stage in the 

 manufacture of a whistle or a tube; they are 62 and 111 mm. long. 

 Both ends of another tube, made from the long bone of a deer or 

 antelope, are cut square. The cancellous tissue is removed and the 

 ends are scored (fig. 23, i) . 



Two other bones seem to be stages in the manufacture of bone 

 tubes. One of these is the proximal end of a deer or antelope meta- 

 podial. It is 36 mm. long, and the distal end was transversely cut to 

 a depth of 4 mm. and snapped off. Another specimen appears to be 

 the proximal end of an eagle humerus. At a point below the humeral 

 head, where the bone is oval, it was transversely cut and the end 

 snapped off. Neither of these latter two bones was otherwise modified. 



Owncellous tissue ohraders (3 specimens) : 



These oval pieces of cancellous bone have rounded surfaces which 

 suggest they were used as abraders. They do not seem to be "paint 

 brushes" since they retain no paint in the interstices. Each seems 

 to be made from a femoral head ; they are 35 to 40 mm. in diameter 

 (fig. 24, e).
