We consider four (real or complex) dimensional hyper-Kähler metrics with a conformal symmetry K . The three-dimensional space of orbits of K is shown to have an Einstein-Weyl structure which admits a shear-free geodesics congruence for which the twist is a constant multiple of the divergence. In thi
