Much dexterity, especially in the case of fine skins, is
required in this operation to avoid cutting or tearing. The operator
places the fleshy side of the skin over the knife, grasps the two ends
of the skin, and placing his knee upon it and slowly drawing the skin
across the knife edge, he brings his weight to bear upon it. If the
operator is skilled and experienced the skin yields quickly, when
needed, to the strain applied and a uniform texture is secured. The
operation of transforming the skin into leather is now finished, but
age is necessary to secure perfect pliability and softness. The skins
are, therefore, laid away to let the slow chemical operation going on
within them be completed.
The visitor can now watch the further processes of manufacture by
visiting the dye rooms. Skins which have already been aged are
immersed in dye vats, where the delicate colors are imparted to them.
The same care is not required in obtaining the ordinary range of dark
colors, for these are "brushed" on, the skin being spread upon a glass
slab and the dye being painted on with a brush. After they are dyed
the skins are sometimes somewhat hard, and in some classes have to be
staked again in order to restore their pliability.
