The wall was more than 4000 km long .It was initially made of dead, thorny material such as the Indian Plum and not built out of mortar or bricks.
But later it evolved into a living hedge known as The Great Hedge or Inland Customs Line. The hedge was 12 feet high in some parts.
The line ran from the Punjab till Orissa. The Inland Customs Department employed customs officers, Jemadars and men to patrol the line.
