Abstract
Let S be a smooth surface in Euclidean 3-space and let C be a smooth curve having its end points on S. Consider a surface x, bounded by the configuration <S,C>, which minimizes Dirichlet's integral. We describe the local behaviour of x at the points where the arc C meets the boundary surface S.
