 Uenuku himself, combed, oiled, and tied the hair of every last one of them, except Ruatapu.When Ruatapu asked why his father had not treated his hair, Uenuku told him he could not because he was the only son of a slave woman, and his hair was not tapu like his brothers'.This put Ruatapu to shame, and so he refused to eat dinner that night, instead going down to the canoe and putting a hole in its bottom, before filling it with wood chips and hiding the canoe's bailer.
