We attempt to predict the mass of the t-quark from the approach based on duality and unitarity, employing the values of known Regge slopes and vector meson masses. The t-quark mass is shown to be bounded approximately by 65 GeV, using the maximum possible value for the γ slope. This upper bound is sensitive, however, to the γ slope, and hence it will be considerably reduced if the reliable value is obtained. The importance to find the χb state ((bb)3P2) is emphasized. The χb mass is also predicted to be less than 9.89 GeV.
