  We consider the motion of a vortex in an asymptotically homogeneous
condensate bounded by a solid wall where the wave function of the condensate
vanishes. For a vortex parallel to the wall, the motion is essentially
equivalent to that generated by an image vortex, but the depleted surface layer
induces an effective shift in the position of the image compared to the case of
a vortex pair in an otherwise uniform flow. Specifically, the velocity of the
vortex can be approximated by $U \approx (\hbar/2m)(y_0-\sqrt 2 \xi)^{-1}$,
where $y_0$ is the distance from the center of the vortex to the wall, $\xi$ is
the healing length of the condensate and $m$ is the mass of the boson.
