Studies of large-scale structure of the universe are providing, at              the present time, the strongest constraints on models of the early              universe.  There is good evidence for complex structure on the                  scale of 30 to 60 million light years that may be compatible with               current models, however, the larger 150 to 300 million light year               structures, still controversial, pose a much greater difficulty.                A chief ambiguity in interpretation is that galaxy distributions                may present a biased mapping of the distribution of mass.                       However, velocity mapping - measuring deviations from a smooth                  Hubble flow - makes it possible to infer all the mass and allows                simple comparison with theory and model simulations.                                                                                                            Three programs that follow from the mapping of the local Hubble                 flow with elliptical galaxies will be carried out.  The original                study found a large-scale flow pattern pointing toward the                      intersection of the galactic and supergalactic planes.  One of the              programs is a redshift survey to map the "Great Attractor", an                  enormous overdensity in the galaxy distribution that may be                     responsible for the flow pattern.  The second program is to carry               out more measurements of deviations from pure Hubble flow in this               direction by finding distances to elliptical and spherical                      galaxies using a distance relation and by infering distances to                 spiral galaxies with the (optical) Tully-Fisher relation.  The                  third program is a further investigation of the suitability of the              distance relation to measurement of the Hubble constant.  The                   Hubble constant provides a relation between the redshift and the                distance of a galaxy.
