  I motivate a proposal for modeling, at weak string coupling, the ``Big
Bounce" transition from a growing-curvature phase to standard (FRW) cosmology
in terms of a pressure-less dense gas of "string-holes" (SH), string states
lying on the correspondence curve between strings and black holes. During this
phase SH evolve in such a way that temperature and (string-frame) curvature
remain $O(M_s)$ and (a cosmological version of) the holographic entropy bound
remains saturated. This reasoning also appears to imply a new interpretation of
the Hagedorn phase transition in string theory.
