Murthy et. al.(1994) discovered intense UV (1100 \AA) emission from the directi on of the Coalsack Nebula. We have used their results in conjunction with a Mon te Carlo model for the scattering in the region to show that the scattering is from dust in the foreground of the Coalsack molecular cloud. We have constrained the albedo of the grains to 0.4 $\pm$ 0.1. This is the first determination of the albedo of dust in the diffuse ISM in the FUV.
