The impact of nonrenormalizable gluon operators upon inclusive jet cross
sections is studied. Such operators could arise in an effective strong
interaction Lagrangian from gluon substructure and would induce observable
cross section deviations from pure QCD at high transverse jet energies.
Comparison of the theoretical predictions with recent CDF data yields a lower
limit on the gluon compositeness scale Λ. We find \Lambda > 2.03 \TeV
at 95%~CL.Comment: 12 pages with 2 figures not included but available upon request,
