Query: Neutrino Mass: Where Do We Stand, and Where Are We Going?   We discuss the three major hints of neutrino mass: the strong evidence of
mass from the behavior of atmospheric neutrinos, the very promising further
hint from the behavior of solar neutrinos, and the so-far unconfirmed hint from
the LSND experiment. Then, we describe two illustrative neutrino-mass scenarios
suggested by the observed hints. We identify the needed future tests of both
the present hints and the neutrino-mass scenarios.
