We present a spline collocation method for the numerical solution of a system of integral equations on a polygon in ĝ2. This integral equation arises if one solves the first boundary value problem for the Lamé equation with a double layer potential. The derivation and the analysis of the integral equation is given in detail. The optimal order of the spline collocation method is proved for sufficiently graded meshes.
