We present FUSE spectra of the Wolf-Rayet binary Sk 108 from 980 Angstroms to 1180 Angstroms. The Vmag=12.3 star is located in the northeastern part of the main ``bar'' of the Small Magellanic Cloud. Individual photon counts were extracted from the astigmatic images on the LiF detector, and a resolution in excess of 15000 was achieved in these commissioning phase exposures. The interstellar lines are fit to a predetermined line-of-sight velocity model for the interstellar clouds (Welty et al. 1997, Ap.J., 489, 672). We report the resulting preliminary column densities for molecular hydrogen, nitrogen, oxygen, argon and phosphorous in groupings of the 25 components known on this line-of-sight based on kinematics and relative abundances. Interstellar O 6 within the SMC in this direction will be discussed. Funding for this project has been provided by the NASA contract NAS5-32985.
