We have carried out a simulation of quantum chromodynamics using the hybrid-molecular-dynamics algorithm with two flavors of Kogut-Susskind quarks. We have used Kogut-Susskind and Wilson valence quarks to calculate the hadron mass spectrum. Among our extensive results we discuss baryon hyperfine splitting, the nucleon-to-{rho} mass ratio, the sclar-to-tensor-glueball mass ratio, and the quantization and susceptibility of the topological charge. We have used a gauge coupling of 6/{ital g}{sup 2}=5.60, and quark masses {ital am}{sub {ital q}}=0.025 and 0.01, in generating gauge configurations on 12{sup 4}, 12{sup 3}{times}24, and 16{sup 4} lattices.
