Abstract
We present the current status of our ongoing calculations of the light hadron spectrum with both Kogut-Susskind (KS) and Wilson quarks in th e valence or quenched approximation. We discuss KS quarks first and fi nd that the chiral extrapolation is potentially the biggest source of systematic error. For the Wilson case, ive focus on finite volume and source size effects at 6/g(2) = 5.7. We find no evidence to support th e claim that there is a finite volume effect between N-s = 16 and 24 o f approximately 5%.
