  Di-jet production is studied in collisions of quasi-real photons radiated by
the LEP beams at e+e- centre-of-mass energies 161 and 172 GeV. The jets are
reconstructed using a cone jet finding algorithm. The angular distributions of
direct and double-resolved processes are measured and compared to the
predictions of leading order and next-to-leading order perturbative QCD. The
jet energy profiles are also studied. The inclusive two-jet cross-section is
measured as a function of transverse energy and rapidity and compared to
next-to-leading order perturbative QCD calculations. The inclusive two-jet
cross-section as a function of rapidity is compared to the prediction of the
leading order Monte Carlo generators PYTHIA and PHOJET. The Monte Carlo
predictions are calculated with different parametrisations of the parton
distributions of the photon. The influence of the `underlying event' has been
studied to reduce the model dependence of the predicted jet cross-sections from
the Monte Carlo generators.
