Canny lass, I found this in the" Durham mining museum- mining occupations". I'm sure HPW will have a better explanation ! also describe a "scuffler"
A man whose business it is to attend to the rolley-way and keep it in order. It is also his duty to keep away the work, and see that no time is lost in getting the full waggons to the shaft and the empty ones in-bye again. His wages are about 2s. 9d. for 8 hours, or 3s. 4d. if he stands 12 hours (1849).
