These cases are by no means numerous, nor do I for a moment want to suggest that it is common for an outcast to have a secret hoard. But such phenomena do exist, and they are generally recruited from the educated classes. They have not always been homeless, but have become Arabs of the pavement through circumstances allied to an inborn dislike of ordered routine. Very often these people disappear from the homeless world and return to the place from whence they came. But I do not think they permanently stay there. There is an urge about street life difficult to resist, and once you have experienced the stimulus of an almost complete isolation, there is a danger that you may indulge in it too often.
