We study the two-point correlations of cosmic-string loops with numerical simulations of the evolution of a cosmic-string network in an expanding universe. We find that the initial positions of loops that are chopped off the network have a correlation function that is quite similar to the highest estimates of the Abell-cluster correlation function, but these correlations are rapidly washed out by the motion of the loops. The implications for the cosmic-string galaxy-formation scenario are briefly discussed.
