  We report new measurements of the neutron-deuteron elastic scattering cross
section at energies from 135 to 250 MeV and center-of-mass angles from
$80^\circ$ to $130^\circ$. Cross sections for neutron-proton elastic scattering
were also measured with the same experimental setup for normalization purposes.
Our $nd$ cross section results are compared with predictions based on Faddeev
calculations including three-nucleon forces, and with cross sections measured
with charged particle and neutron beams at comparable energies.
