In order to obtain a census of the pre-stellar and star-forming molecular cores, we have begun an unbiased survey in CS and N2H+ of the L1630 and L1641 molecular clouds. The use of these two molecular species enables us to quantify and disentangle the effects of depletion often seen in CS observations of dense cores. The spectral line data will provide essential kinematical information not present in similar studies of the sub-millimeter dust-continuum, enabling us to examine the overall core to core velocity dispersion and study the effects of infall and outflows around known sub-mm and infra-red sources. Here we present our initial observations of part of L1630, taken during the commissioning phase of the FCRAO On-the-Fly Mapping system in January 2002.
