Using a "field theoretic" approach, we compute the topological susceptibility X of the pure gauge SU (3) theory on the lattice. We also apply an algorithm of gradual cooling, and use these two approaches as a cross-check on each other. The final value we find for X confirms results found earlier using an abrupt-cooling algorithm.
