Of industries depending on agriculture, the sugar industry is the most important, Poland coming after Germany, France and Czechoslovakia as a sugar-producing country. Whereas agricul ture was formerly encouraged in Poznan, it suffered from gov ernmental opposition and neglect in Russian Poland and in Galicia. Further, the war ruined the industry, which, in 1924, had reached only 26% of its early production. There were 76 sugar factories in 1924, producing 438,070 tons. The production increased to 502,380 tons in 1927 and was estimated at 515,000 tons in 1928. In 1927 205,000 tons were exported. Distilling is an impor tant industry, since Poland has the second largest potato crop in Europe, but brewing has suffered much from the war. The wood and paper industries are also important. Other notable industries are the chemical industries, cement, glass, salt and tanning. The last named has its centre in Warsaw ; the salt mines are chiefly near Cracow. The present productive power of Polish industries seems small compared to that of 1913 ; compared with that of x921 it seems enormous.
The greatest technical problem was the adaptation to the new directions of trade. From being strategic lines and channels of exploitation leading to Leningrad, Vienna and the German centres, the systems had now to provide abundant communication with Danzig and (later) Upper Silesia. Equally serious were the diffi culties of administration—first in replacing the German employees in the former German areas, and then the more enduring difficulty of training a personnel. But by the end of 1923 the technical condition of the railways was in a satisfactory condition, the im provement being largely due to the advice of American engineers.
The long and numerous waterways are the natural means of transport for much of Polish traffic, but repairs to the banks, dredging and other work is sorely needed. Capital and organiza tion have been lacking, however, and little has been done.
Under Socialist influence, room has been found for much un skilled labour in the railways and other Government services, which is alleged to hamper the efficiency of these young adminis trations and increase the deficit in the State budget. Trade union policy has maintained the large number of public holidays, ex tended the practice of the eight-hour day, and increased the number of men on the pay-roll of industry. The ability of Polish industry to compete with foreign, and especially German, industry has been very much restricted, and Polish finances have suffered. Other factors depress the standard of comfort, notably the housing shortage, which with Poland's expanding population is perhaps more intense than anywhere in Europe. The repair of about 6o% of the war damage has done something to relieve the agricultural areas (until 1921 hundreds of thousands of people lived in holes in the ground), but in the towns no family may by law retain for its own use more rooms than its own number plus one.
