The economic revolution in industry and trade has also largely affected agricultural conditions. The commercial and industrial crises affect the rural population likewise. Hundreds of thousands of members of the families of farmers are temporarily or permanently employed in industrial establishments of various kinds. This manner of employment constantly expands, firstly, because the great number of small farmers do not have enough work on their own farms to keep themselves and the members of their families usefully employed, and, secondly, because the large farmers find it profitable to have an important portion of the products of their soil transformed into industrial commodities right on their own farms. In this manner they save the heavy expense of shipping the raw material, for instance, potatoes and grain for the manufacture of alcohol, beets for sugar, cereals for flour or for brewing beer, etc. They, furthermore, are enabled to establish a mutual relation between agricultural and industrial production and can employ the labor power on hand to better advantage. The wages are lower and the workers are more willing too than those in cities and industrial centers. Expenses of buildings and rents as well as taxes are considerably lower too, for the large land owners in the rural districts are both the makers and executors of the law; they furnish many representatives from their midst and control the administration and police force. That is why the number of factories in the country increases each year. Agriculture and industry are becoming more and more closely linked, and the large agricultural establishments mainly profit from this fact.
