In fig. 1 two implements are sketched within the outlines of flakes that might readily have served as blanks for such specializations. The outlines have been traced from common forms of outer flakes selected as far as practicable to correspond in proportions with the included imple- ments. In each case the section through the long axis shows the nearly unaltered flake section still present in the implement. Elabo- rated outlines are thus clearly seen to be specializations of the flake. Tlie length of the flake and the length of the implement correspond in the specimen «, while in b the width of the flake has become the long axis of the imj)lement. This is shown by the location of the per- cussion notch [x) and in the character of the curves of the section. An oblique diameter often became the long axis of the implement when the blank oflered some irregularity of thickness or outline. Alignment of the edge by grinding is shown in both specimens. Bejectage.—Tiejectage which has necessarily occurred during special- izing operations is not particularly abundant. The number of rejects.
