Results are reported from a study of photon-proton collisions at a c.m. energy of 52.6 GeV, in which a charged hadron with large transverse momentum is emitted near 90° in the c.m.s. Paris of particles opposite in azimuth to the trigger particle with transverse momenta above a fixed value show evidence for jet-like structures. Methods to isolate jet-like groups of particles are compared on the basis of a simple model of jet events. Results on the distribution and internal properties of jets from proton-proton collisions are presented, using one of these methods. The jets are found to be very similar in structure to jets observed in e+e- annihilations and in %nu;p scattering, but have about 20% higher multiplicity mainly originating at small x{norm of matrix}. The charge of the jets is correlated with the charge of the trigger particle.
