The purpose of this article is to attempt to reconstruct Jan Czekanowski’s researches conducted between April 1908 and April 1908 in the basin of the Uele River in Central Africa. The basis for reconstruction was the fragment of the original, hitherto unpublished manuscript, Diary of the anthropologicalethnological column of the expedition to Central Africa in the years 1907–1909, written according to the requirements of the organisers during the expedition. This manuscript has not been published to date, although it is preserved in a very good condition, with almost two full sets of texts written in German (fragments are written also in French, Polish and African languages). The collection is stored in the Department of Manuscripts of the Warsaw University Library, deposited there by Anna Czekanowska, the daughter of the researcher. It comprises 11 notebooks and one folder with a total quantity of 1,187 cards.
