We make a quenched lattice simulation of hadron spectroscopy at beta=6.2 with
the Wilson action non-perturbatively improved. With respect to the unimproved
case, the estimate of the lattice spacing is less influenced by the choice of
input hadron masses. We study also the effects of using an improved quark mass
in the fits to the dependence of hadron masses upon quark masses.
