  We have extended our previous study of the lattice QCD spectrum with 2
flavors of staggered dynamical quarks at $6/g^2=5.6$ and $am_q=0.025$ and 0.01
to larger lattices, with better statistics and with additional sources for the
propagators. The additional sources allowed us to estimate the $\Delta$ mass
and to measure the masses of all mesons whose operators are local in time.
These mesons show good evidence for flavor symmetry restoration, except for the
masses of the Goldstone and non-Goldstone pions. PCAC is observed in that
$m_\pi^2 \propto m_q$, and $f_\pi$ is estimated. Use of undoubled lattices
removes problems with the pion propagator found in our earlier work. Previously
we found a large change in the nucleon mass at a quark mass of $am_q=0.01$ when
we increased the spatial size from 12 to 16. No such effect is observed at the
larger quark mass, $am_q=0.025$. Two kinds of wall source were used, and we
have found difficulties in getting consistent results for the nucleon mass
between the two sources.
