  We report the discovery of tidal tails around the two outer halo globular
clusters, Eridanus and Palomar 15, based on $gi$-band images obtained with
DECam at the CTIO 4-m Blanco Telescope. The tidal tails are among the most
remote stellar streams presently known in the Milky Way halo. Cluster members
have been determined from the color-magnitude diagrams and used to establish
the radial density profiles, which show, in both cases, a strong departure in
the outer regions from the best-fit King profile. Spatial density maps reveal
tidal tails stretching out on opposite sides of both clusters, extending over a
length of $\sim$760 pc for Eridanus and $\sim$1160 pc for Palomar 15. The great
circle projected from the Palomar 15 tidal tails encompasses the Galactic
Center, while that for Eridanus passes close to four dwarf satellite galaxies,
one of which (Sculptor) is at a comparable distance to that of Eridanus.
