In 1936, Johannes Lukas published a monograph on "Logone". Though he had never visited the region of Logone-Birni where the language is spoken, he had, nevertheless, met two men in Maiduguri who originated from that region. He was also acquainted with the data collected by Gustav Nachtigal in the previous century. The quality of Lukas's work can be assessed by anylising - together with present-day speakers of Logone - a short story he collected. In particular, one can observe that the transcription in the original language was superior to the German translation. This can be explained by the conditions of communication which held between this great German scholar and his informants.
