This map, showing the progress being made in the land registry surveys, gives an insight into the enormous task of assessing the net income of agricultural land as normally farmed. The work of assessing income and land values was carried out in “assessment districts”, which were in turn sub-divided, with an effort being made to divide each district of between 180,000 and 200,000 hold (Hungarian acres, about 220,000 to 285,000 English acres) into not more than two smaller parts.
