held directly or with a short handle, and have served for 
cutting or hewing rather than for purposes of projection. A 
fine specimen of this kind, composed of red jaspery slate, has 
a length of nine inches, tapering at one end to a rounded 
point and narrowed to a sort of handle at the other, while 
either side is bevelled from the median line to a rather sharp 
edge. Others are like arrow-heads in size and shape, but are 
left thick and blunt on one side, with a cutting edge on the 
other. They are always flaked. 
Ornamented Stones. (Plate II. Figs. 6, 7, 8). Among 
the articles found at Maquapit Thoroughfare, near Indian 
Point, Grand Lake, are several which are interesting as 
exhibiting attempts at surface ornamentation. In each case 
these objects are of a narrow lanceolate form, tapering at 
one end to a point and hence bearing some resemblance to 
spear or lance-heads; but in each case the flattened sides are 
markedly divided into three well-defined parallel zones, which 
run the whole length of the article and are inclined to each 
other at a considerable angle, while (on one side only) the 
central, or all three of these zones, is conspicuously marked 
and ornamented with incised lines. Where central, these 
lines run obliquely down from right to left at an angle of 45°, 
and are remarkable for their regularity, and in one instance, 
for their number and fineness; but when found on all three 
faces, those on the sides are uniformly oblique (downward 
from right to left), while those of the middle form a more 
complex pattern, inclining right and left alternately in zig- 
zag fashion. In two instances the material composing these 
ornaments is a fine black slate, in another a light colored and 
apparently magnesian slate. The fineness of the incisions 
points to the use of sharply pointed instruments and a 
considerable degree of skill in their manufacture. They are 
represented in Plate II., Figs. 6, 7, 8, but owing to the 
delicacy of the markings, these can scarcely be recognized in 
the photograph. 
Hammers and Hammerstones. (Not figured). The articles 
included under this head are, from their nature, somewhat 
indefinite and variable, any stone, of whatever shape, having
