  We study the spectrum of $H(m)=\gamma_5 W(-m)$ with $W(m)$ being the
Wilson-Dirac operator on the lattice with bare mass equal to $m$. The
background gauge fields are generated using the SU(3) Wilson action at
$\beta=5.7$ on an $8^3\times 16$ lattice. We find evidence that the spectrum of
$H(m)$ is gapless for $1.02 < m < 2.0$, implying that the physical quark is
massless in this whole region.
