“ In general physical characteristics the province resembles East Prussia, but the climate is less harsh and the fertility of the soil greater. Arable land and gardens occupy 55.6% of the area, meadows and pastures 12.9%, forests 21.7%, and the rest is mostly waste. The valley and delta of the Vistula are very fertile, and produce good crops of wheat and pasturage for horses, cattle and sheep. Besides cereals, the chief crops are potatoes, hay, tobacco, garden produce, fruit and sugar-beet. Poultry, fish and timber are important sources of wealth. ”
