  We present an investigation of gauge invariant smearing for Wilson fermions
on a $24^3 \times 48$ lattice at $\beta = 6.2$. We demonstrate a smearing
algorithm that allows a substantial improvement in the determination of the
baryon spectrum obtained using propagators smeared at both source and sink, at
only a small computational cost. We investigate the matrix of correlators
constructed from local and smeared operators, and are able to expose excited
states of both the mesons and baryons.
