Galaxy formation scenarios predict a burst of star formation in normal galaxies at a redshift between z D 2 and z D 6 (e.g., Katz & Gunn 1991) such a starburst may be accompanied by a signicant brightening of the j \ 158 km line of C. Galaxies that will evolve to a total luminosity L * \ 5 ] 1010 in L _ the current era are considered at various redshifts. When the C luminosity is evolved in accordance with a starburst scenario, the expected spectral line antenna temperature at the focus of a 10 m telescope is about 2 mK for galaxy models at redshifts up to that at which the starburst occurs. Such a spectral line is detectable with current submillimeter wavelength instrumentation at good submillimeter-wave sites like the South Pole. If the telescope were equipped with an array receiver and wide-bandwidth spectrometers (100 channels distributed over 5 GHz), a "" blank sky survey for such objects would likely detect several hundred during a winter of observation. The number and distr.
