26 CLUB TYPES OF NUCLEAR POLYNESIA. 
club, and even the finger-thick rootlets shown in the picture are quite 
as effective as the larger roots, for the density of the wood of the 
Casuarina is extreme. In the same plate, figure 3 exhibits somewhat 
more of the perception of the possibility of utilizing the natural form 
of the rootstock in the shaping of ahead. In the specimens we see the 
recognition of the tap-root as distinctly a part of the design, as also 
in figures 5 and 6. In figure 2, however, the tap-root motive has dis- 
appeared entirely; despite this loss it is most clear that. the domed 
head with its regularly cut bosses is a conventionalizing of the treat- 
ment of the head which meets the eye in figure 3. The club illustrated 
in figure 1 is grouped here for convenience, and a recension of a greater 
number of pieces in other museum possession may suggest a new

source. In figure 2 there is a dome somewhat more than hemispher- 
ical, studded with bosses regularly spaced, the dome rather sharply 
marked off from the swelling of the shaft by a plane space with a little 
suggestion of guttering. In figure 1 is found a plain dome considerably 
less than a hemisphere; the single row of extremely formal bosses is not 
upon the dome at all, but rather on the swelling of the shaft; the inter- 
spaces between the bosses show no suggestion of sharp demarcation 
between shaft swelling and head dome. Noting these diversities, this 
piece is admitted to the classification only temporarily. 
The record of the measurements of these pieces, beginning with the 
length over all, is found in table 6. 
In comparison of the similar measurements of the billet type of club 
a slight adjustment is needed. Among the billets are 6 pieces less than 
37 inches long. ‘The rootstocks exhibit none of the short clubs; there- 
fore we compare with the longer billets, 17 in number, and this is suffi- 
ciently close to the 16 pieces of this group to serve as a comparison base. 
Between the lengths of 38.5 and 42.25 inches are 7 rootstocks and 9 © 
billets; between the lengths of 43 and 46 inches the record is exactly 
reversed—g rootstocks and 7 billets. This difference may not be sig- 
nificant, yet is worthy of record. 
The circumference of the shaft, the first measurements being taken 
at the end of the haft, is recorded in table 7.
