KIDDER-GUERNSEY] ARCHEOLOGICAL EXPLORATIONS IN ARIZONA 181 
fully worked piece of limestone;' and by another in the Free 
Museum of Science and Art, Philadelphia (a replica is on exhibi- 
tion in the Brooklyn Institute of Arts and Sciences), which, accord- 
ing to Cushing’s label,’ has: “ wild-cat tooth fastening of finger 
loops with ‘ Feather Cleaver’ Lightning stone (knife or arrow of 
chalcedony), war fetish stone, and ‘Blood Clot’ of limonite, and 
wrappings of dyed cotton yarn originally decorated with bright- 
feather work.” 
Even after making due allowance for Cushing’s bias toward the 
mystic, it seems clear that the attached objects in this particular 
case must have been ceremonial in nature, but as to the others we 
are still in doubt. 
It has occurred to the authors that the stones might perhaps be, 
so to speak, ceremonialized relics of former useful parts of the atlatl, 
but their researches in this direction brought out very little evidence. 
Traces of attached objects, apparently inlaid, are to be seen on an 
ancient atlatl from Yucatan in the Peabody Museum, and on an 
example from Bering Sea there is a small ivory figure fastened to 
the back. To throwing sticks from New Guinea are tied carved fig- 
ures, but these are placed on the edge of the shaft where they 
served to keep the dart from slipping sideways.* Peruvian throw- 
ing sticks bear attached pieces of stone or bone that were used to form 
a handgrip.* Neither of these cases is, however, really comparable 
to ours; the nearest approach is seen in a throwing stick from the 
upper Rio Negro, Brazil (Peabody Museum), which has carved 
in high relief on its back a curious double-ended contrivance; there 
are also notches at the sides as if for wrappings (see fig. 88, a). 
DARTS 
As to the length of the projectiles thrown with the atlatl we 
have no data; their general make-up, however, is well illustrated 
by a number of broken darts found in the general digging in Cave 
I. The main shafts are of some light but strong wood with a small 
pith “ heart.” The butt of each is provided with a shallow cup to en- 
gage the spur of the throwing stick (fig. 89, 6, c), and the ends are 
wrapped with a fine sinew seizing to keep the spur from shoving too 
far into the cup and thus splitting the shaft. 
The feathering method is indicated, but not wholly made clear, by 
the two specimens reproduced in figure 89; 6 seems to show a double 
attachment similar to that of Lower Yukon darts (fig. 89, a, intro- 
duced for comparison).
