Processes in Tunning.
The new processes used In tanning are most surprising. Leather used to be tanned by seeking, it for seven days In a weak solution of hemlock or oak bark to give it color, then hi pits of stronger solution for six weeks, moving the bides every day or so; then In “layaway” pits still stronger for another alx weeks; by filling them with new bark for another six weeks’ soak, and repeating this last operation thrice or four times. All this made good leather, but It took from six to eight months. even the thickest bide can be tanned by chemicals in three hours.
