  Gamma-ray burst statistics are best explained by a source population at
cosmological distances, while spectroscopy and intensity histories of some
individual bursts imply an origin on Galactic neutron stars. To resolve this
inconsistency I suggest the presence of two populations, one at cosmological
distances and the other Galactic. I build on ideas of Shemi and Piran (1990)
and of M\'esz\'aros and Rees (1993) involving the interaction of fireball
debris with surrounding clouds to explain the observed intensity histories in
bursts at cosmological distances. The distances to the Galactic population are
undetermined because they are too few to affect the statistics of intensity and
direction; I explain them as resulting from magnetic reconnection in neutron
star magnetospheres.
