Data from e+e- annihilation into hadrons collected by the JADE experiment atcentre-of-mass energies between 14 and 44 GeV were used to study the 4-jet rateusing the Durham algorithm as well as the first five moments of event shapeobservables. The data were compared with NLO QCD predictions, augmented byresummed NLLA calculations for the 4-jet rate, in order to extract values ofthe strong coupling constant alpha_S. The preliminary results are alpha_S(MZ) =0.1169 +/- 0.0026 (4-jet rate) and alpha_S(MZ) = 0.1286 +/- 0.0072 (moments)consistent with the world average value. For some of the higher momentssystematic deficiencies of the QCD predictions are observed.Comment: Contribution to proceedings of ICHEP 2004, Beijing, China, 4 page
