We present WHAM observations of \mathrm { H } \alpha , [ N II ] , and [ S II ] in the Smith Cloud . A map of \mathrm { H } \alpha emission from the cloud shows ionized gas coincident with the brightest H I emission , but nearly-as-bright \mathrm { H } \alpha in some regions with faint H I . The ionized mass of the cloud is at least as large as the neutral mass , > 10 ^ { 6 } M _ { \odot } . Ionized gas in the core of the Smith Cloud has an electron temperature 6000 \textrm { K } < T < 16000 \textrm { K } . The observed ratio \textrm { [ N II ] } / \mathrm { H } \alpha = 0.39 \pm 0.09 shows that the cloud has a non-primordial nitrogen abundance , 0.1 - 1 \times solar .
