Excess strangeness production is an expected signal for formation of a Quark-Gluon Plasma and therefore we have been searching for it. We present the first measurements at AGS energies of rapidity distributions of K{sub s} and {Lambda} production with silicon beams on Silicon and Lead targets. The measurements cover the lab rapidity region of 2.0 < y < 3.5 for K{sub s} and 1.4 < y< 3.2 for {Lambda}`s. the gross features of our observation are explainable with a nuclear cascade model including N* (isobaric nucleon) as a significant source of strangeness. The various models used to compare with the data are discussed in the paper.
