He iahiko, he ngaru autōhiko rānei, ka kawe raraunga mai i tētahi pūrere matihiko ki tētahi. Ka puta te iatohu i te pūrere tuku, ka haere i rō waea (iahiko), ka haere rānei i te takiwā (ngaru autōhiko) ki te pūrere whiwhi.

He ngoikore noa iho te iatohu e taetae mai ana ki taku waea pūkoro i konei.
Ka hurihia ngā raraunga hei waehere tāhūrua, koirā te iatohu raraunga ka tukuna hei ngaru autōhiko.
Ki te kore e kaha te iatohu kāore e pai ana te pāhotanga mataora.
