lage on the point of land southwest from the cemetery at Mans- 
field, Penn., now owned by the writer, and over which the 
cemetery is being extended. The place commands a fine view 
of the river valley up and down for many miles, and is by nature 
one of the most delightful locations in northern Pennsylvania. 
It is a neck of land, thirty or more feet in height, projecting 
from the terrace of drift which borders the river plain, and was 
covered with a heavy pine forest when first seen by the white 
man. It contains some five or six acres, and is rich in relics ; 
the soil, which is a gravelly loam, having been originally filled 
with them. They were manufactured here from material ob- 
tained somewhere to the north, and one can readily detect the 
location of the wigwams or dwellings by the number of flint 
chips, etc., found in certain places. Implements, both finished 
and ina partially finished state, have been ploughed up during 
mapy years, and although the writer has collected many hundreds 
of them, the place is not yet exhausted, but continues to furnish 
specimens whenever the ground is newly ploughed. ‘These were 
made in a number (but more particularly in two) places, at 
which were doubtless workshops or habitations. I have picked 
up over two hundred arrow points, a number of pestles, a num- 
ber of polished implements used, evidently, in the dressing of 
hides, some stone axes, a large number of stones used as sinkers 
on fish-nets, as well as various other things, including several 
(probably ten), bushels of flattened sandstone cobbles. These 
cobbles average three or four inches through the broad diameter, 
and have round, pointed holes cut or pecked in one or both (gen- 
erally both) sides, one-eighth to one-half inch in depth, and of 
which the accompanying specimens are good examples. The 
arrow points are mostly of dark-colored flint, and are as a rule 
very small, though not always so, and were, I have surmised, 
used and lost by boys in practising upon a mark. But one 
white one has been found, a beautiful specimen of fair size 
(which may have a history of its own), and a few of a yellowish, 
and some of a reddish color. There are three or four different 
styles represented ; one made to fasten to the arrow in the ordi- 
nary manner, one made to give the arrow a revolving motion 
while passing through the air, and another—the poisoned point 
—made to insert into the end of the arrow without fastening, 
in such a manner that it could not be withdrawn without leav- 
ing the point imbedded in the flesh. The flattened cobbles re- 
ferred to, with a hole picked in each side, are a riddle which I 
have not as yet been able to solve. Part at least if not all were 
evidently obtained from the river bed, where they have been wash- 
ed down from the coal measure sandstones at Blossburg, ten miles 
above; but I cannot imagine what they were used for, or how the
