  The possibility of a gaseous halo stream which was stripped from the
Sagittarius dwarf galaxy is presented. The total mass of the neutral hydrogen
along the orbit of the Sgr dwarf in the direction of the Galactic anticenter is
4-10 x 10^6 Msun (at 36 kpc, the distance to the stellar debris in this
region). Both the stellar and gaseous components have negative velocities in
this part of the sky, but the gaseous component extends to higher negative
velocities. We suggest this gaseous stream was stripped from the main body of
the dwarf 0.2 - 0.3 Gyr ago during its current orbit after a passage through a
diffuse edge of the Galactic disk with a density > 10^{-4} cm^{-3}. The gas
would then represent the dwarf's last source of star formation fuel and
explains how the galaxy was forming stars 0.5-2 Gyr ago.
