The properties of high-ET events produced in pp collisions at {Mathematical expression}=63 GeV have been studied at the CERN Intersecting Storage Rings. The fragmentation of the jets is found to be very similar to that of jets produced in e+e- annihilation and at the SPS {Mathematical expression} collider. We measure an excess of soft particles compared with e+e- events and this underlying event is found to be sensitive to the trigger. The pT balance between the jets is measured. The distribution of charges in the jets indicates that a substantial fraction of the jets originate from valence quarks.
