Dr. Meyer concludes his work by saying that he does not believe that an improvement of economic conditions will inevitably lead to an increase of crimes against persons, but that the causes of them are rather to be found in frivolity, grossness, and dissipation consequent upon an improvement of conditions. [PLATE III. (MEYER)] But—youth does not possess wisdom! It is only by advancing in age that rash, rough youth becomes wise and gentle. Now, in the same way society will lose, one by one, the faults of its youth! [PLATE IV. (MEYER)] XV. M. TUGAN-BARANOWSKY. “Die sozialen Wirkungen der Handelskrisen in England”, [74] by this author, aims to prove that the commercial crises in England in the years 1823–1850 had a much more violent character than those of the years 1871–1896, which occurred less suddenly, and made themselves felt for a long time afterwards. Since criminality is one of the social phenomena pointed out as caused by these crises, it is worth while giving a résumé of the work in question. Dr. Tugan-Baranowsky has examined the influence that commercial crises have exercised, first, upon the agricultural counties, Cambridge, Essex, Norfolk, Oxford, Lincoln, Suffolk and Wilts (Diagrams 1 and 4); second, upon the industrial counties of Lancaster and Chester (Diagrams 2 and 5); third, upon all England (Diagrams 3 and 6). Let us study the first three diagrams. The first shows that the commercial crisis of 1825 had a very slight effect upon criminality. It was the high price of grain in 1829 that made crime increase. The same effect was produced by the famous law of 1834 (by which not only was the aid given to poor working people very much limited, but which prescribed the placing in work-houses of those who were without means of support) and by the crisis of 1836. In 1844–1845, years of good harvests, criminality declined, after which the bad crops of 1847 brought about a contrary effect. We note from Diagrams 2 and 3 that the effect of commercial crises was much greater in the manufacturing than in the agricultural counties (more plainly seen in 2 than in 3). The crisis of 1825 made the curve of criminality rise considerably; the favorable years 1833–1836 made it descend from 1834 on; while the crisis of 1836 caused a considerable increase in the number of crimes in 1837. The bad years 1840–1843 caused a formidable increase in the criminal population, which must also be attributed, at least in part, to the Chartist movement. The favorable period that followed had the contrary effect. It is interesting to compare the curves (in Diagram 3) of exports and crime, which cross continually.
