ʻO nā kukui, kahi mea hana kukui i kēlā me kēia lā, i hana nui ʻia me ka paraffin, i ka wā kahiko, i hana ʻia me ka momona holoholona. Hiki ke puhi i ka malamalama. Eia kekahi, hoʻohana ʻia nā kukui no nā kumu like ʻole: i nā pāʻina lā hānau, nā ʻaha hoʻomana, nā kanikau hui, a me nā hanana male a me nā hoʻolewa.
