  We have studied the light hadron spectrum and decay constants for quenched
QCD at beta=6.2 on a 24^3x48 lattice. We compare the results obtained using a
nearest-neighbour O(a)-improved ("clover") fermion action with those obtained
using the standard Wilson fermion action on the same gauge configurations. For
pseudoscalar meson masses in the range 330-800 MeV, we find no significant
difference between the results for the two actions. The scales obtained from
the string tension and mesonic sector are consistent, but higher than those
derived from baryon masses. The ratio of the pseudoscalar decay constant to the
vector meson mass is roughly independent of quark mass as observed
experimentally.
