              The Indus Civilization settlement of Mitathal, District Bhiwani, Haryana is rapidly being leveled due
              to agricultural activities. A short surface reconnaissance was conducted during which, among other
              things, a steatite seal was recovered. A small fragment of that seal was analyzed using instrumental
              neutron activation analysis (INAA) and determined to have been made from raw steatite that most
              probably originated in the Alwar District of northern Rajasthan. This, along with evidence that rock
              outcrops near the Haryana/Rajasthan border were being exploited for manufacture of grinding stones,
              indicates that residents of the site had important trade relationships extending towards the south.
