  In this paper we study the relation between the Frobenius manifolds of GW
theory and Hurwitz-Frobenius manifold. We prove that orbifold GW theory of
\PP^1(2,2,2,2) is isomorphic to the submanifold in the Hurwitz-Frobenius
manifold of ramified coverings of the sphere by the genus 1 curve with the
ramification profile (2,2,2,2) over infinity.
