The role of the $S_{31}$ $\pi N$ partial wave in the three-nucleon force
  We re-examine the contribution of the $\pi N$ $S_{31}$ channel to the three-nucleon force for an energy dependent separable potential. Despite the lack of cancellation between the $S_{31}$ and the $P_{11}$ and $P_{33}$ channels, the total contribution of the three-nucleon force to the triton binding is still small.
