Spectra of 7-Å resolution have been obtained of six red giants in the Draco dwarf spheroidal galaxy by using the Multiple Mirror Telescope. The new spectra confirm that a range in calcium abundance exists among the Draco giants. The calcium variations are also accompanied by correlated variations of the CN and G bands. Most Draco stars appear to be intermediate between M92 and M13 in their heavy-element abundances. The MMT spectra also indicate that one star, 361, has a [C/Fe] ratio higher than is typical of globular clusters. A reanalysis of DDO photometry published by Hartwick and McClure indicates that [C/Fe] enhancements are present among other Draco giants. A possible origin for the Draco anomalies is discussed, and similarities to the globular cluster ω Cen are pointed out. It is suggested that Draco formed from a relatively massive (≡106M_sun;) gas cloud.
