Monte Carlo simulations were made of two- and three-dimensional Ising models containing up to 1503 and 13952 sites in a randomly oriented field ± H. A spontaneous magnetization was observed to build up at low enough temperatures, even if initially the spins were disordered. The time required for this build-up was observed to increase with some power of the system size for short times, and possibly exponentially with the square root of the length for larger times.
