These two hundred and twenty-one outlines are of different objects in various museum collections, not quite one third being on exhibition in Andover and the others in the Peabody Museum, Harvard University; Ohio State Archæological and Historical Society, Columbus; the Field Museum, Chicago; Smithsonian at Washington; the Dominion Museum at Toronto; the Art Museum at Cincinnati, etc. I have omitted the locality of these, but reference to the illustrations presented in this chapter of specimens from all over the country, will give one an idea of the range. Each row is lettered. At the top, A, are the simple forms, pecked and ground and perhaps polished, but not perforated. A begins with the oval and ends in the tablet form with four concave sides. B also begins with the oval, is perforated, and ends in the pendant form. Under the 10th specimen, counting from the left end of row B, I have drawn a small arrow indicating that this form may be traced through another series. This is lettered row C. The sixth specimen, counting from the right towards the left in row B, is a spade-shaped gorget. This may have suggested the true spade form. I have drawn an arrow from this specimen and inserted a number of spud-shaped objects which are lettered D. Row E begins with the simple oval, again, but is doubly perforated. This row ends in the flat tablet, concave sides with two perforations on either side of the centre. The seventh specimen, counting from right to left in this row, has underneath it two arrows, which indicate two other series. The first, row F, ending in the ridged form; second, row H, exhibiting progression in the concavity in the sides until it terminates in the double crescent, or problematical form with curved arms. Opposite the short series F is another series under the same letter, beginning with the second specimen from right to left in row E. This form of tablet may be carried through the series to a highly specialized form with angular depressions on either side of the centre. [Illustration:
