A 42, 
Nos. 15 to 22 in this Case are from California, and were pre- 
sented to the Collection by Captain Oliver Eldridge, of San 
Francisco. No. 15 is a grooved stone axe, in process of manu- 
facture from a seaside pebble, which was somewhat of the shape 
of the implement intended to be made from it. This pebble was 
rendered more symmetrical by ** pecking," and a groove was 
worked around it by the. same process. When finished, the 
pecking" marks would have been more or less removed by 
grinding, as with Nos. 16 and 17. These axes were hafted by 
bending a withe around the groove. In some instances raw 
hide was probably placed over the withe, which, shrinking as 
it dried, would have held the axe-head firmly in its place. 
Implements and weapons hafted in this manner are still in use 
in North America and elsewhere. No. 20, in Case C 40, is a 
modern example ; it was obtained by Mr. Marcou, in August, 
1853, when he was crossing the prairies to the north of Texas. 
He procured it from the Kioways, a branch of the Commanches.
