other objects found on the surface of the sand ridges along the 
eastern side of Saginaw River in the city of Saginaw, indicate a 
number of village sites which were separated by bayous, From 
one of the latter series 
there has been obtained 
one of the so-called 
** bird-shaped *’ stones 
which is evidently in 
process of manufac- 
ture. The greater por- 
tion of the surface 
shows the pits caused 
by “* pecking,”’ as it is 
technically called, that 
is, the bruising of the 
surface of the stone 
and the brushing away 
of the crushed particles 
until it has assumed 
the shape desired. At 
either side of what was 
to have been the head, 
the next process in the 
manufacture had been 
taken up, as is shown 
by the rubbed surfaces. 
It is probable that this 
rubbing was done with 
a rather coarse stone, 
and that the implement 
would have been fin- 
ished by polishing.
