Five documents regarding salt production in Ordos

The notebooks of the late Reverend Antoine Mostaert (1881–1971) contain five documents relating to salt production in the Banner of Otoγ, South Ordos: they appear in notebook 11 (Otoγ) as NT. 46 (May 1920), Nr. 61 (October 1921), Nr. 62 (1886), Nr. 67 (no date), and Nr. 68 (1921, no month or day). These texts are in transcription, evidently copied from originals kept at the Banner administration. Although Fr. Mostaert is mentioned in one of the documents, none was addressed to him, so we cannot assume that the archives of the church of Boro-Balγasuna possessed copies of these documents, unless somebody had copied them from the originals.
