The results of a survey of excess optical continuum emission (veiling) in a sample of 35 K7-M1 pre-main-sequence stars in Taurus-Auriga are reported. Stars with detectable veiling emission always show significant near-infrared K-L excesses. This result agrees with the prediction of a simple accretion disk model, where a boundary layer produces the veiling and the infrared excess comes from the disk. The K-N colors of T Tauri stars fall into two distinct groups: stars in the group with small or absent K-N excesses have no detectable veiling emission, while objects with large K-N excesses usually have detectable veiling. This result also agrees with the prediction of the disk model, where a large K-N excess indicates an optically thick disk, and an optically thick disk is required to generate a mass accretion rate large enough to produce detectable veiling.
