XII. — Rural Economij of the Netherlands ; being a Report read 

 by M. de Lavergne to the Academy of Moral and Political 

 Science. Translated from the ' Journal d'Agriculture Pratique,' 



by H. EVEESHED. 



I HAVE already called the attention of the Academy to a work 

 on the 'Rural Economy of Belgium,' by M. Emile de Laveleye, 

 the professor of Political Economy at the University of Liege, 

 The same author has now given us, in a second publication, 

 an equally interesting picture of the kingdom of the Nether- 

 lands, and I shall now attempt to follow him in his more recent 

 travels. 



The Netherlands, exclusive of the Grand Duchy of Luxemburg, 

 contains 8,190,000 acres, and is nearly as large as Belgium.
