We construct an effective Lagrangian of pions, the vector mesons rho and ..omega.., as well as a scalar meson and a scalar glueball which incorporates chiral symmetry and the QCD trace anomaly. The scalar sector is set up so that it contains particles in a realistic mass range with physically narrow widths. We calculate static nucleon properties and demonstrate that shallow bags with typical confinement sizes of Rapprox.1/2 fm are favored by phenomenology.
