I. _In the Economic Sphere_.--Free Trade (apart from the temporary necessity of protecting a particular manufacturing or agricultural industry), by preventing famines and exceptional high prices of and taxes on food, eliminates many crimes and offences, especially against property.--Unrestricted emigration is a safety- valve, especially for a country in which this phenomenon, assuming large proportions, carries off many persons who are easily driven to crime by wretchedness, or by their unbalanced energy. Thus the number of recidivists has diminished in Ireland, not by virtue of her prison systems, but by emigration, which reached forty-six per cent. of released prisoners. In Italy, also, there has been a decrease <p 115>of crime since 1880, owing to other causes, such as mild winters and plentiful harvests, but also through a vast increase of emigration.--Smuggling, which for centuries resisted extremely harsh punishments, such as amputation of the hand, and even death, and which still resists prison and the fire-arms of the revenue officers, is suppressed by the lowering of the import tariff, as M. Villerm<e'> has shown in the case of France. So that everyday facts justify the system of Adam Smith, who said that the law which punished smuggling, after creating the temptation, and which increased the punishment when it increased the temptation, was opposed to all justice; whilst Bentham, on the contrary, departing from his maxim that the punishment ought to be dreaded more strongly than the offence attracted, called for the stern repression of smuggling.--The system of taxation which touches wealth and visible resources instead of the prime necessaries of life, and which is proportional to the taxpayer's income, diminishes the systematic frauds which no punishment availed to stop, and it will also abolish the arbitrary and exaggerated fiscal traditions which have been the cause of rebellions and outrages. In fact, Fr<e'>gier describes the criminal industries which are called into existence by _octrois_, and which will disappear with the abolition of these absurd and unjust duties. And whilst M. Allard demonstrated that a decrease of taxes on necessaries would have beneficial effects, not only in economic affairs but also in respect of commercial frauds, the Report on French Criminal Statistics for 1872 calmly continued to call for more severe repression of such frauds. To <p 116>this M. Mercier replied that if the cause--that is to say, disproportionate taxes--were not removed, it would be impossible to prevent the effects.--Immunity from taxation for the minimum necessary to existence, by preventing distraint, and the consequent diminution of small properties, which means the increase of the very poor, will obviate many crimes, as we see from the agrarian conditions in Ireland. Thus there is a demand in Italy for the inalienability of small properties, as in America under the Homestead Exemption Law.--Public works, during famine
