Ray Sidney H. A Grammar of the Kiwai Language, Fly Delta, Papua - with a Kiwai vocabulary

Port Moresby, Papua. Edward George Baker, Government Printer, 1931. — 173 p.The grammar here presented is based upon notes and paradigms supplied to me by Mr. Riley or evolved in the course of our correspondence, with examples drawn from the Scriptures or from Folk tales written by natives. Though the material was supplied by Mr. Riley, he left to me the arrangement and elucidation of the complicated grammar. My task was only rendered possible by Mr. Riley's unceasing collection of facts, and his care to ensure that those facts were accurate.
