The house in which the Vanes lived stood in a large and beautiful garden, and both were enclosed by a high brick wall, over which only the waving tops of the trees could be seen from the street. There were a good many such houses in M. at the time my story opens. They were originally built in the country, amid green fields and orchards, where, on summer days, one might sit and look at country sights and listen to country sounds, and quite forget that the hum and bustle of a great town sounded close at hand. As time went on, and commerce prospered, the town extended itself in all directions. Houses, some large and some small, were built near those pleasant country homes, and in a few years stretched far beyond them. Sometimes the gardens were encroached upon, and streets were opened, and building lots laid out and occupied close to the house itself, till only a narrow strip of dusty lawn was left. But in some streets the high brick garden-walls made a blank between great blocks of stores and terraces of dwellings for a good many years, and in some streets there are high brick garden-walls still.
