  We investigate the use of two types of non-local (``smeared'') sources for
quark propagators in quenched lattice QCD at $\beta=6.0$ using Wilson fermions
at $\kappa=0.154$ and $0.155$. We present results for the hadron mass spectrum,
meson decay constants, quark masses, the chiral condensate and the quark
distribution amplitude of the pion. The use of smeared sources leads to a
considerable improvement over previous results. We find a disturbing
discrepancy between the baryon spectra obtained using Wuppertal and wall
sources. We find good signals in the ratio of correlators used to calculate the
quark mass and the chiral condensate and show that the extrapolation to the
chiral limit is smooth.
