  We compare the light hadron spectrum and decay constants for quenched QCD at
$\beta=6.2$ using an $O(a)$-improved nearest-neighbour Wilson fermion action
with those obtained using the standard Wilson fermion action on the same set of
18 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 differ from that derived from baryon masses. The ratio of the
pseudoscalar decay constant to the vector meson mass increases slowly with
quark mass as observed experimentally.
