  The quark-mass dependence of the eta in the Schwinger model, which -- like
the eta-prime in QCD -- becomes massive through the axial anomaly, is studied
on the lattice with N_f=0,1,2. Staggered quarks are used, with a rooted
determinant for N_f=1. In the chiral limit the Schwinger mass is reproduced,
which suggests that the anomaly is being treated correctly.
