First, effective Lagrangians are constructed in a manner consistent with an underlying large-N_c QCD. An infinite set of graphs dress the bare Yukawa couplings at *leading* order in 1/N_c, and are summed using semiclassical techniques. What emerges is a picture of the large-N_c baryon reminiscent of the chiral bag: hedgehog pions for r > 1/\\Lambda patched onto bare nucleon degrees of freedom for r < 1/\\Lambda, where the ``bag radius'' 1/\\Lambda is the UV cutoff on the graphs.
