Shelter for the wounded on furlough: the only home that many soldiers knew

The sick and wounded soldier with his strength and money spent found at all junction points where he had to transfer, when furloughed home, a lodge where he might find a welcome, a good meal, and, if necessary, spend the night. This was partly to protect him from the hosts of sharpers and swindlers who met every train-load of furloughed soldiers and sought to prey upon them. The wives of the superintendents of these lodges were often an important factor in their success.
