Nuclear emulsions were used to establish the upper limits for the production of Dirac monopoles by 6.3-Bev protons. If poles of protonic mass are produced by direct nucleon-nucleon collision, the production cross section is less than 2 x 10/sup 35/ cm/sup 2/ per nucleon. If poles of protonic or lower mass are produced by direct or by secondary processes and are subsequently held in matter with a binding energy less than 3 ev, the production cross section is less than l.5 x l0/sup -37/ cm/sup 2/ per nucleon. If poles of protonic or lower mass are produced by direct or by secondary processes and are subsequently held in matter with a binding energy between 3 ev and 20 ev, the production cross section is less than l0/sup -40/ cm/sup 2/ per nucleon.
