No. 411.] PREHISTORIC WORKSHOPS. 215 
At points at the lower edge of the talus slope and in several 
places on the low peninsula south of the mountain were indica- 
tions of former occupancy by the Indians. Chips and rejectage 
occurred in many places, but the principal workshops were 
located at the points indicated upon the sketch map (Fig. 2). 
Workshops 1 and 2, near the eastern and western ends of the 
cliff, were evidently the principal blocking-out shops. These, 
being near the water, had unfortunately been disturbed and 
partially destroyed by the waters raised by damming. A large 
amount of chips and general shop refuse was found at the 
eastern shop (1). Large discarded worked nodules lay in beds 
of chips. Ashes and charcoal occurred at intervals. A few 
hammer stones were found, all of felsite. The rejectage of 
this shop indicated principally the production of large imple- 
ments. Very few nearly completed implements were found. | 
Workshops 3 and 4 differed principally from those at the 
foot of the talus in the size of the rejectage. Both had been 
somewhat disturbed by the damming of the outlet of the lake 
and the consequent washing away of portions of the shore. 
Workshop 4 had been nearly obliterated, but the abundance 
of refuse along the beach showed the types of implements 
manufactured there. In both these workshops medium and 
small *turtlebacks " predominated. 
The ruder forms of rejects collected from the different 
workshops are illustrated upon Pl. II, æ to e. These occurred 
in great abundance, the larger examples being nearly all from 
the shops at the foot of the talus slope. Types of the second- 
ary forms are shown on Pl. III, e to 4. These were much less 
abundant than the ruder forms. The largest specimen, e, 
measuring eighteen inches in length, was found by Mr. L. L. 
Hubbard in workshop 3, and presented by him to the Peabody 
Museum. 
Comparatively few implements broken in the last stages of 
formation were found. The lengths of the perfect examples 
of which these were a part would range from about three inches 
to ten inches. Unbroken finished or nearly finished imple- 
ments were very rare. They were of the types shown upon 
Pl. III, a to d.
