     Condition problems that apply
specifically to leather objects include
surface abrasions, tears, distortion of
the original shape, excessive dryness
and, less commonly, excessive
wetness, mold, insect infestation and
the fading of dyes and colorants. A
condition called red rot, caused by
excessive acidity in the leather, often
affects late 19th-century instruments.                                                         Fig. 5: This detail of an Ojibwe rawhide
