Abstract

We present the current status of our ongoing calculations of the light hadron spectrum with both Kogut-Susskind (KS) and Wilson quarks in the valence or quenched approximation. We discuss KS quarks first and find that the chiral extrapolation is potentially the biggest source of systematic error. For the Wilson case, we focus on finite volume and source size effects at 6/g2 = 5.7. We find no evidence to support the claim that there is a finite volume effect between N3 = 16 and 24 of approximately 5%.
