We have obtained spectra near 3130 Å of 23 F and G main-sequence stars at 0.05 Å px−1. We have made preliminary estimates of the equivalent widths for the Be II doublet at 3130.4 and 3131.1 Å by means of a comparison procedure that matches each star against a standard star of similar spectral type with known Be abundance. It appears that stars that are deficient in Be are very uncommon. The halo dwarf, HD 76932, clearly has Be.
