  We discuss two issues related to the physics of center vortices in pure SU(N)
lattice gauge theory at large N: (1) Center vortices are stable classical
solutions of the Wilson action, as well as of a wide class of improved lattice
actions, for any N > 4. (2) The natural scaling of k-string tensions at large
N, in the vortex picture of confinement, is \sigma(k)=k \sigma(1). This is the
common large N limit of Casimir and Sine Law scaling. The crucial feature for
explaining this behavior is the existence of center monopoles.
