It is not easy to estimate the number of persons who become habitual mendicants in consequence of slackness of work and the temporary loss of employment. As a matter of fact the whole body of statistical information bearing upon vagrancy is rather unreliable in character, and it is difficult to see how it can be anything else. In almost all cases of begging the initiative is taken by the police; it very seldom happens that a private citizen gives a beggar in charge. The regular and systematic enforcement of the Vagrancy Acts by the public authorities is impeded by a variety of causes, each of which makes it difficult to grasp accurately the proportions of the begging population. In the first place no two policemen enforce the law with the same stringency; one is inclined to be lax and lenient, while another will not allow a single case to escape. In some districts chief constables do not care to bring too many begging cases before the local magistrates; in other districts chief constables are zealous for the rooting out of vagrancy. In some counties the magistrates themselves are not so anxious to convict for vagrancy as they are in others; where the latter tendency prevails, the police take their cue from the magistrates and comparatively few offences against the Vagrancy Acts are brought up for trial. Again, there are times when the public have fits of indulgence towards beggars, which are counterbalanced at other periods by a corresponding access of severity; these oscillations of public sentiment are immediately felt by the executive authorities. The conduct of policemen and magistrates towards the begging fraternity is largely shaped by the dominant public mood, and the statistics of vagrancy move up and down in sympathy with it. Thus it comes to pass that the variations which take place in the annual statistics of vagrancy do not necessarily correspond with the growth or diminution of the number of persons following this mode of life; the actual number of such persons in the population may in reality be varying very little or, perhaps, remaining stationary, whilst official statistics are pointing to the conclusion that important changes are going on. In short, the statistics of vagrancy are more useful as affording a clue to the state of public sentiment with respect to this offence than as offering an accurate test of the extent to which vagrancy prevails.
