From 1904 until 1912 he was in the Bechuanaland Protectorate Police Force. His duties as a policeman and magistrate took him into the most remote parts of the territory, one of the his missions being the Damaraland frontier at the time of the Herero and Nama Wars in German South-West Africa. He was also much involved in trying to reconcile conflicts between tribal chiefs. His several political missions cover a most important period of the history of Botswana.

One of his journeys, in 1906, was made in the company of Sir Ralph Williams, Resident Commissioner, and was from Serowe to Livingstone and the Victoria Falls via Lake Ngami.
