We compute from lattice QCD in the valence (quenched) approximation thepartial decay widths of the lightest scalar glueball to pairs of pseudoscalarquark-antiquark states. These predictions and values obtained earlier for thescalar glueball's mass are in good agreement with the observed properties of$f_J(1710)$ and inconsistent with all other observed meson resonances.Comment: 12 pages of Latex, 3 PostsScript figures as separate uufil
