  After deriving the classical Ward identity for the variation of the action
under a change of the modulus of the torus we map the problem of the sphere
with four sources to the torus. We extend the method previously developed for
computing the classical conformal blocks for the sphere topology to the tours
topology. We give the explicit results for the classical blocks up to the third
order in the nome included and compare them with the classical limit of the
quantum conformal blocks. The extension to higher orders is straightforward.
