The bird-stones with projection on either side, which by some are called ears, and by others eyes, are quite frequently found in the eastern United States, and Canada. An unusual one is illustrated in Fig. 402, this having one button-shaped knob on the top of the head. Figs. 406 and 409 from the collection of Mr. Hills illustrate bird-stones about one third size, from various portions of Indiana, Ohio, and Canada; an unfinished one in Fig. 409 (number on its side 561) is interesting in that the bill or nose is unusually long, the head high, and the body quite short. One beautiful specimen owned by Mr. George Little of Xenia, Ohio, is illustrated in Fig. 410, and the specimen is turned in Fig. 411 so that the perforations are visible. The neck of this is unusually long. It will be observed that all of these bird-stones have flat bases; none of the bases are round. In Figs. 404 to 411 are presented bird-stones, Class I, divisions A and B. Naturally, there are more of plain bird-stones (A) than those with large projecting ears, or elaborate heads. It will be observed that the width of the tail varies, being long and narrow in some, short and slightly flaring in others, and in still others broad, or fan-shaped. Sometimes the eye is very small, as in the lower left-hand specimen, Fig. 405. Or it may be sunken, several of which are shown in Fig. 409. But usually it is worked in high relief. There are presented, all told, in this chapter, sixty bird-stones. It would be possible for me to present ten times this number. There are included in the series numbers of effigy-like objects that might not be classed by other observers as bird-stones. For instance, the central specimen, top row, of Fig. 405.
