sidian, is in fragments too small to be utilized
except as a grinding or polishing material for smoothing wrought
objects.

Manufactured stone specimens are confined principally to three general
classes: Adzes, for working in wood; pestles, for pounding the taro
root; and discoids, for games. The last are exactly similar to the
chunkey stones so abundant in the States, except that none of them
have concave or hollowed faces, and they are used in the same way.
There were three forms of the game: To hurl or roll a disk farther
than an opponent; to strike a pole or other mark set up; and to test
the inherent magical powers of the stones by rolling them in such a
way that they would collide, the object in this case being to see
which one might prove victorious by breaking the other or forcing it
out of its course. A suitable arena for the contest was prepared by
carefully leveling and smoothing a straight, narrow strip of ground to
any length desired, a slight wall being thrown up along each margin.

Pottery was unknown, there being no clay suitable for making it.
Calabashes or gourds and wooden trays served as receptacles, though
stone dishes or bowls are sometimes found. Along the coast occur
sinkers, either plummet-shaped or half-ovoid like an egg divided
lengthwise. This form has a groove around the longer diameter,
crossing the flat face, and was tied to a white shell as a sinker in
catching squids or cuttlefish, a hook being attached to the line.
Coral was much used as files or rasps. There are a few objects whose
purpose is problematical; and some highly polished black disks which,
laid flat and covered with a film of water, make excellent mirrors;
but aside from what is here mentioned, not much worked stone is found.
Wood, bone, and shell served as the raw material for nearly all other
needs.

Graves, or what are supposed to be graves, marked by cairns 3 or 4
feet high, or perhaps by only one or two layers of stones, are found,
though rare. Many so-called caves--which are merely "tunnels,"
"bubbles," or "blow-holes" in the lava--were utilized as burial
vaults. The natives vigorously protested against an attempt to
excavate any of these, claiming that their ancestors or members of
their families are buried in them and must not be disturbed. In the
dunes human skeletons are frequently exposed by the shifting of the
sands by the high wind. The natives seem to have little regard for
these. Perhaps they are of the "c
