THE porphyritic felsite of MVIt. Kineo, Moosehead Lake, was one of the chief minerals used for the manufacture of chipped implements by the tribes of central and southern Maine. Chips and broken implements of this stone were found in nearly all of the camp sites and shell heaps which I have examined in that state. The oldest New England people of whom we have knowledge, and whose art remains were taken from the very ancient graves explored by me in Hancock County, Maine, in I892-94, used knives of this mineral. Although erratic bowlclers of this stone furnished a limited supX a ply of material, the chief source / was the great cliff of Kineo. a The southern side of this mounFIG.

Its opposite side slopes gradually to the wooded plain forming the northern portion of the peninsula. In connection with other archaeological work in Maine carried on under the auspices of the Peabody Museum of Harvard University, the writer made two visits to Mt. Kineo, for the purpose of locating Indian workshops and learning the manner in which the rock was quarried or otherwise obtained. The talus slope at the foot of the great cliff of Kineo (Fig. I, a) is from two hundred to three hundred feet in width and extends the entire length of the mountain. Patches of evergreens interspersed with deciduous trees are growing near its base, but its surface is practically free from soil. The slope of the talus is composed of comparatively small fragments 213
