A measurement is presented of the two-jet differential cross section, d^3σ/dE_T dη_1 dη_2, at center of mass energy sqrts = 1800 GeV in proton-antiproton collisions. The results are based on an integrated luminosity of 86 pb^-1 collected during 1994-1995 by the CDF collaboration at the Fermilab Tevatron collider. The differential cross section is measured as a function of the transverse energy, E_T, of a jet in the pseudorapidity region 0.1 < |eta_1| < 0.7 for four different pseudorapidity bins
