duced Umi to
declare war against him.

He took the field at the head of his army, accompanied by his famous
warrior, Piimaiwaa; his friends, Koi and Omakamau; his favorite, Pakaa;
and Lono, his Kahuna. He turned the flanks of Mauna Kea, and advancing
between this mountain and Hualalai, in the direction of Mauna Loa, arrived
at the great central plateau of the island, intending to make a descent
upon Kailua. Keliiokaloa did not wait for him. Placing himself at the head
of his warriors, he marched to meet Umi. The two armies met on the high
plain bounded by the colossi of Hawaii, at the place which is called _Ahua
a Umi_.

Two men of the slave race, called Laepuni, famous warriors of Keliiokaloa,
fought with a superhuman courage, and Umi was about to fall under their
blows, when Piimaiwaa, coming to his rescue, caused the victory to incline
to his side. Although history is silent, it is probable that the king of
Kailua perished in the battle.

This victory completely rid Umi of his last rival; he reigned henceforth
as sole ruler of Hawaii; and to transmit to posterity the remembrance of
this remarkable battle, he caused to be erected on the battle-field, by
the people of the six provinces, Hilo, Hamakua, Kohala, Kona, Ka'u, and
Puna, a singular monument, composed of six polyhedral piles of ancient
lava collected in the vicinity. A seventh pyramid was raised by his nobles
and officers. In the centre of these enormous piles of stone he built
a temple, whose remains are still sufficiently perfect to enable one to
restore the entire plan. The whole of this vast monument is called, after
the name of its builder, the Heaps of Umi--_Ahua Umi_.

Umi built another temple at the foot of Pohaku Hanalei, on the coast of
Kona, called _Ahua Hanalei_. A third temple was also erected by him on
the flank of Mauna Kea, in the direction of Hilo, at the place called
Puukeekee. Traces of a temple built by the same king may also be
recognized at Mauna Halepohaha, where are found the ruins of Umi's houses
covered with a large block of lava.[17]

They give Umi the name of King of the Mountains. Tradition declares that
he retired to the centre of the island, through love for his people, and
these are the reasons which explain the seclusion to which he devoted
himself. It was a received custom in Hawaiian antiquity that the numerous
attendants of the chiefs, when traversing a plantation, should break
down the cocoa-nuts, lay waste the fields,
