This dissertation describes my contribution to the efforts of the CLEO collaboration. The measurements were done using the CLEO detector at the Cornell Electron Storage Ring, CESR, CLEO is a large magnetic detector. A short description of the CLEO detector is given with a more detailed description of the Inner Z proportional chamber. This chamber consists of a set of three nested cylindrical PWC's with both anode read out and cathode strip read out. The cathodes provide accurate positional information along the beam direction, to be used to improve the driftchamber charged track reconstruction. Charged hadrons, ..pi..'s, Kaons, and protons are identified through their time of flight as measured by the time of flight counters in CLEO. Inclusive cross sections and hadron production per event has been determined. An increase in proton production on the narrow UPSILON (1S and UPSILON (2S) resonances and a suppression of proton production on the UPSILON (4S) is observed as compared to that of the nearby e/sup +/e/sup -/ continuum. An increase in Kaon production is observed for all resonances.
