  The pion-nucleon scattering amplitudes are calculated in tree approximation
with the use of the extended linear sigma model (ELSM) as well as heavy baryon
chiral perturbation theory (HB$\chi$PT), and the non-relativistic forms of the
ELSM results are compared with those of HB$\chi$PT. We find that the amplitudes
obtained in ELSM do not agree with those derived from the more fundamental
effective approach, HB$\chi$PT.
