  We compare light hadron spectroscopy using the Wilson and Clover fermionic
actions. We show that a Clover coefficient chosen using tadpole-improved
tree-level perturbation theory effectively eliminates the O(a) discretization
errors present in the Wilson action. We find that discretization errors in
light spectroscopy for both the Wilson and Clover actions are characterized by
an energy scale mu of about 200-300 MeV, indicating that these errors can be
reduced to the 5% level by using the Clover action at an inverse lattice
spacing of about 1.3 GeV.
