We report the results of the first direct search for grand-unified-theory magnetic monopoles with adequate sensitivity to detect a flux as small as the Parker flux limit. If stable monopole-nucleus bound states exist then the observed absence of monopole tracks in our 4.6 x 10/sup 8/-yr-old mica detector places an upper limit of 10/sup -17/ to 10/sup -16/ cm/sup -2/ sr/sup -1/ s/sup -1/ on the flux of grand-unified-theory monopoles having velocity 3 x 10/sup -4/c to 1.5 x 10/sup -3/c.
