  We report Sr, Pd and Ag abundances for a sample of metal-poor field giants
and analyze a larger sample of Y, Zr, and Ba abundances. The [Y/Zr] and [Pd/Ag]
abundance ratios are similar to those measured for the r-process-rich stars CS
22892-052 and CS 31082-001. The [Pd/Ag] ratio is larger than predicted from the
solar-system r-process abundances. The constant[Y/Zr] and [Sr/Y] values in the
field stars places strong limits on the contributions of the weak s-process and
the main s-process to the light neutron-capture elements. Stars in the globular
cluster M 15 possess lower [Y/Zr] values than the field stars. There is a large
dispersion in [Y/Ba]. Because the r-process is responsible for the production
of the heavy elements in the early Galaxy, these dispersions require varying
light-to-heavy ratios in r-process yields.
