  The Josephson current between d-wave superconductors is investigated in the
framework of tight-binding lattice model. The junction is modelled by a small
number of connecting bonds. It is obtained that the Josephson current through
one bond vanishes when at least one of the superconductors has $(110)$
interface-to-crystal orientation. Interference between the nearest bonds is
appeared to be very important. In particular, it is the interference term that
leads to the nonzero Josephson current for $(110)$ orientation. Also,
interference of two connecting bonds manifests itself in non-monotonic behavior
of the critical Josephson current in dependence on the distance between the
bonds.
