Poverty compels men to live under conditions in which their vices may easily develop into crimes or offences; and it makes those who have transgressed the law less able to recover from the effects of a conviction and more liable to become habitual offenders; but it cannot be said that the amount of convictions in Scotland is in relation to the poverty of any given district. In some parts of the highlands and islands, where poverty is pronounced, there is an entire absence of crime. While no ratio can be traced between the amount of drinking or the degree of poverty and the number of crimes or offences in Scotland, there is a very definite relationship between the density of the population and the incidence of breaches of the law. Not only is there more crime in the city than in the country, but from the densely populated parts of the city there are more committals than from the less crowded districts. The sanitary reformer has shown us that our city slums are breeding-places for diseases that do not confine their operation to the people who dwell there, but may easily infect those who live under more wholesome conditions; and substituting vice and crime for disease and death the statement is equally true. By letting in light and fresh air to the houses where so many dwell we are able to save lives which would otherwise be crippled or destroyed by the insanitary conditions in which they are placed; and just as surely we could break up the aggregations of people whose acquired way of living is fatal to the proper development of an enlightened civic spirit, if we were as eager to prevent as we are to punish wrongdoing. There they are; born into little boxes of houses which are packed together in rows and built in layers one above the other in the air. Their home life is passed in similar boxes; and when they die they are put in smaller boxes and placed in layers under the earth. The health officer would speedily interfere if we tried to house as many pigs to the acre as human beings; but we eat the pigs and cannot permit them to be raised under conditions that would be likely to result in their contracting disease. Also there are fewer people making a living by furnishing accommodation for pigs than for men; and it is easier to regulate an occupation when those who are engaged in it are not influential, than when they are; for we have a traditional dislike to interfering with the rights of property. It is therefore much easier to punish a slum-dweller for breaking our sanitary regulations than a slum landlord for living off rotten dwellings.
