An analytic map h of type Bl from a Riemann surface R into another S, both having Greens functions, behaves well near the “boundaryr” of R. Let X stand for a family of holomorphic functions, and let f be holomorphic on S. We shall show, for several X′s, the following:

(i) fX(S)fohX(R);

foh‖ = ‖f‖.

Use is made of harmonic majoration of subharmonic functions on R and on S.
