Metal abundance measurements that were made for 84 globular clusters are used to describe the cluster system of the Galaxy. There is a metal abundance gradient between the clusters within 9 kpc of the galactic center and the clusters more distant than 9 kpc. There is a metal abundance gradient with distance from the galactic plane among the clusters within 9 kpc of the galactic center. The strength of the second parameter phenomenon varies systematically with galactocentric distance; hence regardless of whether this phenomenon is caused by age or composition variations, it is related to the large-scale evolution of the Galaxy. If age is the second parameter, then the outer halo clusters formed later over a longer period of time than the metal-poor clusters in the inner halo.
