  We present chemical abundances for 110 stars identified in objective-prism
surveys as candidates to be very metal-poor. The abundances are derived from
high S/N, intermediate-resolution spectra obtained with the Keck Observatory
Echelle Spectrometer and Imager. An additional 25 stars with well-determined
abundances ranging from [Fe/H]$=-1.5$ and -3.2 were observed and the results
used to help calibrate our analysis and determine the accuracy of our abundance
determinations. Abundances for the program stars were measured for Fe, Mg, Ca,
Ti, Cr and Ba with an accuracy of approximately 0.3 dex. 53 of the stars in our
sample have [Fe/H]<= -2, 22 have [Fe/H]<= -2.5 and 13 stars have [Fe/H]<= -2.9.
Surprisingly, approximately one third of the sample is relatively metal rich
with [Fe/H]>-1.5. In addition to identifying a number of extremely metal-poor
stars, this study also shows that moderate-resolution spectra obtained with the
Keck Echelle Spectrometer and Imager yield relatively accurate abundances for
stars as faint as V=14 in modest exposure time (~20 minutes). This capability
will prove useful if the so-far elusive stars at [Fe/H]<-4 turn out to be
mostly fainter than V=15.
