  We prove the connectedness and calculate the diameter of the oriented graph
of graftings associated to exotic complex projective structures on a compact
surface S with a given holonomy representation of Fuchsian type.
  The oriented graph of graftings is the graph whose vertices are the
equivalence classes of marked CP^1-structures on S with a given fixed holonomy,
and there is an oriented edge between two structures if the second is obtained
from the first by grafting.
