The evolution of density perturbations around cosmic strings in the matter-dominated era is discussed with attention to the specific nature of string perturbations. The parameter G..mu.. is calculated in two completely independent ways: from the requirements that Abell clusters are formed and that the galaxy-galaxy correlation function matches the observed one. Both values are consistent, lending support to the cosmic string theory.
