It is a notable proof of the hold which Catholic ideas have upon the people in this part of France, that notwithstanding a marked tendency to emigration among the peasantry of the Boulonnais and of Artois, the population has steadily increased through the excess of births over deaths. This is not true of France as a whole. On the contrary, while the deaths in France in 1888 were 837,857, against an annual average of 847,968 from 1884 to 1887, the births diminished from an annual average of 937,090 between 1881 and 1884 to 882,639 in 1888, leaving the small excess of 44,772 over the deaths. Of these only 33,458 were of French parentage! In Artois and the Boulonnais, the population is more dense than in any other part of France, excepting the metropolitan regions. While France, as a whole, in 1881, gave an average of seventy inhabitants to the square kilometre, which is the precise proportion in Bavaria--the arrondissement of Bethune in the coal-mining country of Artois (fed by an exceptional immigration from Belgium) gave 173 to the square kilometre, which exceeds the proportion in any division of the German Empire except Saxony, Luebeck, Bremen, and Hamburg. The Department of the Pas-de-Calais, as a whole, gave 117 inhabitants to the square kilometre, which is the precise proportion in Saxe-Altenburg, and exceeds by five the proportion in the British Islands taken as a whole. In the arrondissement of St.-Omer the rate of increase by natural growth some years ago outran that of the older sea-board States of the American Union. This phenomenon cannot be explained by the improvidence of the Artesians, for they are admittedly remarkable, even in France, for their frugality and their forecasting habit of mind. A friend of mine, who lives near St.-Omer, is probably right when he attributes it to their strong domestic tastes and habits, and to the influence over them of their religion. He says they are 'fanatics of the family.' Certainly in the cottages the children seem to have things all their own way, almost as much as in America. 'The Artesian parents,' my friend tells me, 'make their children the objects of their lives.' In the rural regions there is not much immorality. Concubinage, which is by no means uncommon in the towns, is exceedingly uncommon in the country of Artois.
