  We study the 4-probe bend conductance $G_{14,32}$ of a mesoscopic crossed
wire structure in the ballistic regime in the absence of a magnetic field,
which for normal devices is usually negative. We predict that for sufficiently
large devices and for small applied voltages $G_{14,32}$ becomes positive in
the presence of Andreev scattering, but at large voltages $G_{14,32}$ remains
negative.
