Question

How can a historian derive from such surveys ?

Answer 1

they can only know the important things from official letters, newspapers,etc. Those records only tell about main incidents, not the actual mind set of people

But if they look deeper into the matter, by surveys of villages , they may find the mind sets of people in those days.

Answer 2

Surveys in any field is very important and crucial in the sense that it helps one to collect the right data, figures, information and reports regarding a subject. To a historian, surveys are equally important because a historian is related to history and all the information are related to the past. To the historians, archeological surveys are important because it deals with the past. A historian can come across certain information like – the ancient civilizations, the behaviors of human beings in the past, structure of the society, the culture and the traditions, habits and their livelihood. These are important because the historians can assess actual information prevalent during the period and what transformations has been brought or will be taking place in future.
