were a broken taro pestle and a very dense siliceous rock, of high
specific gravity, and filled with olivines. It weighs about 75 pounds.
The ends have been chipped off to give it an ellipsoidal form,
otherwise the wave-worn surface is unworked, except that one of its
larger faces is rubbed smooth, almost polished, by use as a grinding
stone, for which purpose it is excellently adapted by reason of its
unusual abrasive quality.

MAUI ISLAND

There are not many aboriginal structures on Maui, but among those
which can be found are some of extreme interest on account of their
size and complicated arrangement.

KAUPO, OR MOKULAU

A mile and a half from the coast at Kaupo, or Mokulau landing, at the
eastern end of the island, are two large heiaus. As it would have
required a week's time and a considerable outlay of money to reach
them, by reason of the distance and lack of roads, they were not
visited.

WAILUKU

At the mouth of the Iao Valley, a mile north of Wailuku, is a sand
dune having a nearly level area of about an acre at each end,
connected by a curved ridge whose sharp crest is lowered about 20 feet
by erosion. On each extremity is a stone inclosure, with several walls
on the slopes below them except on the eastern side, toward the ocean.
Here a stream has encroached upon the bottom of the dune to such an
extent that only a portion of the inclosure nearer town is still
remaining, one side and part of each end having fallen into the
ravine. The wall along the opposite, or western, side is buried in the
sand, only the highest stones still projecting. From the north wall a
facing of large stones extending down the surface of the dune for a
vertical distance of 15 feet has prevented erosion by the winds. No
protection was necessary below this point as the action of rain water
on the lime from disintegrated coral rock contained in the deposit has
caused the sand to "set" or harden.

The other heiau, at the north end of the dune, is apparently
unfinished. None of it has disappeared, but the plan is difficult to
make out. At its northern end is a protecting layer of stones reaching
25 to 30 feet down the slope, in three separate terraces. Similar
terraces are on the slope below the southern end of the east wall.
Here and there within the structure are well-like spaces filled with
stones. The purpose of these is unknown. Stones of varying sizes,
mostly small, within the
