  We present a sample of 8321 candidate Field Horizontal-Branch (FHB) stars
selected by automatic spectral classification in the digital data base of the
Hamburg/ESO objective-prism survey. The stars are distributed over 8225 square
degrees of the southern sky, at |b| > 30 deg. The average distance of the
sample, assuming that they are all FHB stars, is 9.8 kpc, and distances of up
to ~30 kpc are reached. Moderate-resolution spectroscopic follow-up
observations and UBV photometry of 125 test sample stars demonstrate that the
contamination of the full candidate sample with main-sequence A-type stars is <
16%, while it would be up to 50% in a flux-limited sample at high galactic
latitudes. Hence more than ~6800 of our FHB candidates are expected to be
genuine FHB stars. The candidates are being used as distance probes for
high-velocity clouds and for studies of the structure and kinematics of the
Galactic halo.
