On August 11, 1920 the first car was driven into Hermannsburg. Heinrich wrote a report of the event in an article for the "Lutheran Herald" (1922). According to the report, while the arrival of the vehicle generated enormous interest and excitement, it also 'greatly scared some of the abos, especially the switching on of the electric lights. To set lamps alight without applying matches or fire,' he wrote, 'seemed a bit supernatural to the abos' (p 117).
