The harrows and drills are worked in "gangs" as the Seeding' ploughs were.
Our earliest information about the land and its people is derived from geological, ethnological and archaeological studies, from the remains in British harrows and caves, Roman roads, walls and villas, coins, place-names and inscriptions.
In the same way the villagers had to go through the work of harrowing with their harrows, and of removing the harvest in their vans and carts.
The method once exclusively used consists in mixing the raw materials with a large quantity of water in a wash mill, a machine having radial horizontal arms driven from a central vertical spindle and carrying harrows which stir up and intermix any soft material placed in the pit in which the apparatus revolves.
The earlier period is characterized by the practice of inhumation in harrows made of clays, stones or sand, according to the district.
