Abstract
In Table 47, tonnages shown before 1869 are estimated. After that time they are partly estimated from the total tonnage handled by the Allegheny Valley Railroad from four counties, of which this was one. Several reports to state authorities give a few figures, all probably very low, as is shown by the return in 1880 to the Secretary of Internal Affairs. [ ]
