Fig. 403. (S. 1–1 and 1–2.) These three problematical forms are from the Provincial Museum collection, Ontario, Canada. The upper one is from central Ontario. The base view of the lower specimen is also shown.

Fig. 404. (S. 1–2.) Andover collection.

Fig. 405. (S. 1–4.) W. A. Holmes’s collection, Chicago.

Figs. 399, 400, 401, and the central object in Fig. 269 are all unfinished bird-stones. It was difficult for me to procure these, but after some years of correspondence they were obtained.

The specimens clearly show the work of the hand-hammer. Fig. 401 and the upper right-hand specimen in Fig. 399 have been pecked into shape and the grinding-polishing process was well under way when the specimen was set aside, or lost.

Fig. 406. (S. about 1–3.) Collection of Leslie W. Hills, Fort Wayne, Indiana.
