We present optical spectroscopy of H {\sc ii} regions in the Local Groupgalaxy IC 10 and $UBVR$ photometry of foreground stars in three fields towardsthis galaxy. From these data, we find that the foreground reddening due to theMilky Way is $E(B-V)=0.77\pm 0.07 \mathrm{mag}$. We find that IC 10 containsconsiderable internal dust, which qualitatively explains the variety ofreddening values found by studies of its different stellar populations. Basedupon our foreground reddening, IC 10 has intrinsic photometric properties likethose of a blue compact dwarf galaxy, and not those of a dwarf irregular. Thisresult is consistent with much evidence that IC 10 is in the throes of astarburst that began at least $10 \mathrm{Myr}$ ago. We also report thediscovery of a new WR star in the H {\sc ii} region HL111c

IC 10: More evidence that it is a blue compact dwarf
