review text: The pair approximation of the cluster variation method is applied to the hole theory of classical fluids and the melting transition of the hard- sphere system is discussed. The exact free volume of the hard-sphere molecule is used to make up an effective 'interaction' assigned to a cluster which consists of an occupied site by a molecule and its nearest neighbour sites occupied by molecules and holes. This method supplies much improved results compared with those of the molecular-field approximation which corresponds to the site-approximation in the cluster variation method.
