Observations consisted of 2 x 1000\nsec exposures with the 400 lines/mm grating, with the source at an\nairmass ~ 2.  Based on the presence of a strong continuum break around\n7250A which we identify as due to Ly alpha, we estimate a redshift of z\n= 4.9.\n\n\nPAP thanks Nestor Mirabal for helpful discussion.  We also thank the\nGemini North observing team for performing these observations.",
