  New measurements of neutron-capture elements are presented for two very
metal-poor stars ([Fe/H] ~ -3). One (LP 625-44) has an s-process signature
believed to be due to mass transfer from a now-extinct metal-poor AGB
companion, and the second (CS 22897-008) is one of a number of very metal-poor
stars having high [Sr/Ba] ratios which is not expected from the r-process. In
the s-process star, many elements including lead have been detected, providing
strong constraints on the 13C pocket in the now-extinct AGB star. In the
Sr-rich star, Zn, Y, and Zr are also seen to be overabundant, and several
possible nucleosynthesis mechanisms are discussed.
