  Using the tadpole improved clover Wilson quark action on small, coarse and
anisotropic lattices, $KN$ scattering length in the I=1 channel is calculated
within quenched approximation. The results are extrapolated towards the chiral
and physical kaon mass region. Finite volume and finite lattice spacing errors
are also analyzed and a result in the infinite volume and continuum limit is
obtained which is compatible with the experiment and the results from Chiral
Perturbation Theory.
