RURAL ECONOMICS. 



The agricultural laborer, L. Thomassin (Bui. Hoc. Agr. France, 1910, Apr. 

 1, pp. 20-26). — This is a paper read before the Agricultural Society of France, 

 February 23, 1910. 



The author made a study of tbe economic and social conditions surrounding 

 the life of farm laborers in the Vexin district, with a view of determining the 

 chief causes of rural depopulation and of suggesting means for the repopula- 

 tion of the land. As far as wages are concerned, the farm laborers in this 

 section of France are shown to receive from 85 to 120 francs per month with- 

 out board, from 50 to 70 francs per month with board, and other premiums 

 according to the amount of milk produced, sheep sold, lambs raised, and wool 

 produced. Day laboi-ers receive 3 francs per day without board and 2 fi'ancs 

 with board. The economic position of farm laborers, therefore, is regarded as 

 comparing favorably with the lot of industrial workers. 



The social position of the farm laborer, however, is regarded as capable of 

 great improvement and as the chief cause of rural depopulation. To improve 

 conditions it is recommended that good houses should l)e erected with attached 

 gardens, that facilities be afforded for keeping i)oultry, pigs, rabbits, etc., to
