Wailuku River, the Home of Kuna.
"Ah! Nothing can withstand the magic club. The bank around one end of the dam gives way. The imprisoned waters leap into the new channel. Safe is Hina the goddess."
Kuna heard the crash of the club against the stones of the river bank and fled up the river to his home in the hidden caves by the pools in the river bed. Maui rushed up the river to punish Kuna-mo-o for the trouble he had caused Hina. When he came to the place where the dragon was hidden under deep waters, he took his magic spear and thrust it through the dirt and lava rocks along one side of the river, making a long hole, through which the waters rushed, revealing Kuna-mo-o's hiding place. This place of the spear thrust is known among the Hawaiians as Ka puka a Maui, "the door made by Maui." It is also known as "The natural bridge of the Wailuku river."
Kuna-mo-o fled to his different hiding places, but Maui broke up the river bed and drove the dragon out from every one, following him from place to place as he fled down the river. Apparently this is a legendary account of earthquakes. At last Kuna-mo-o found what seemed to be a safe hiding place in a series of deep pools, but Maui poured a lava flow into the river. He threw red-hot burning stones into the water until the pools were boiling and the steam was rising in clouds. Kuna uttered incantation after incantation, but the water scalded and burned him. Dragon as he was, his hard, tough skin was of no avail. The pain was becoming unbearable. With cries to his gods he leaped from the pools and fled down the river. The waters of the pools are no longer scalding, but they have never lost the tumbling, tossing, foaming, boiling swirl which Maui gave to them when he threw into them the red-hot stones with which he hoped to destroy Kuna, and they are known today as "The Boiling Pots."
Some versions of the legend say that Maui poured boiling water in the river and sent it in swift pursuit of Kuna, driving him from point to point and scalding his life out of him. Others say that Maui chased the dragon, striking him again and again with his consecrated weapons, following Kuna down from falls to falls until he came to the place where Hina dwelt. Then, feeling that there was little use in flight, Kuna battled with Maui. His struggles were of no avail. He was forced over the falls into the stream below. Hina and her women encouraged Maui by their chants and strengthened him by the most powerful incantations with which they were acquainted. Great was their joy when they beheld Kuna's ponderous body hurled over the falls. Eagerly they watched the dragon as the swift waters swept him against the dam with which he had hoped to destroy Hina; and when the whirling waves caught him and dashed him through the new channel made by Maui's magic club, they rejoiced and sang the praise of the mighty warrior who had saved them. Maui had rushed along the bank of the river with tremendous strides overtaking the dragon as he was rolled over and over among the small waterfalls near the mouth of the river. Here Maui again attacked Kuna, at last beating the life out of his body. "Moo-Kuna" was the name given by the Hawaiians to the dragon. "Moo" means anything in lizard shape, but Kuna was unlike any lizard known in the Hawaiian Islands. Moo Kuna is the name sometimes given to a long black stone lying like an island in the waters between the small falls of the river. As one who calls attention to this legendary black stone says: "As if he were not dead enough already, every big freshet in the stream beats him and pounds him and drowns him over and over as he would have drowned Hina." A New Zealand legend relates a conflict of incantations, somewhat like the filling in of the Wailuku river by Kuna, and the cleaving of a new channel by Maui with the different use of means. In New Zealand the river is closed by the use of powerful incantations and charms and reopened by the use of those more powerful.
In the Hervey Islands, Tuna, the god of eels, loved Ina (Hina) and finally died for her, giving his head to be buried. From this head sprang two cocoanut trees, bearing fruit marked with Tuna's eyes and mouth.
In Samoa the battle was between an owl and a serpent. The owl conquered by calling in the aid of a friend.
This story of Hina apparently goes far back in the traditions of Polynesians, even to their ancient home in Hawaiki, from which it was taken by one branch of the family to New Zealand and by another to the Hawaiian Islands and other groups in the Pacific Ocean. The dragon may even be a remembrance of the days when the Polynesians were supposed to dwell by the banks of the River Ganges in India, when crocodiles were dangerous enemies and heroes saved families from their destructive depredations.
