Excerpt from Zinc and Lead Deposits of the Upper Mississippi Valley SO far there are not many branch lines to the mines, though a few have been built in the Hazel green-benton district. In general, coal and supplies must be hauled to the plants by wagon at a cost of 40 cents to $2 a ton, and the ore must also stand a wagon haul to the cars.
