The CDF collaboration collected 19.5 pb{sup {minus}1} of data during the 1992--93 collider run at Fermilab. Using these data the inclusive jet cross section is measured in the pseudorapidity ({eta}) range 0.1--0.7. The transverse energy (E{sub T}) range of the jets extends from 15 to 440 GeV. The measured cross section is compared with next-to-leading order ({Omicron}({alpha}{sub s}{sup 3})) QCD predictions for various parton distributions and different choices of renormalization scale. A new limit on {Lambda}{sub c}, a term representing quark substructure, is derived. The two-jet differential cross section is measured by determining the E{sub T} spectrum of central jets (0.1 < {vert_bar}{eta}{vert_bar} < 0.7) for different {eta} intervals of the second jet which span the range 0.1 < {vert_bar}{eta}{vert_bar} < 3.0. The results are compared with leading order QCD calculations.
