Terra-cotta models show that the two-wheeled ox-cart was familiar to the Harappans, apparently with solid (probably "three-plank") wheels comparable with the semi-solid wheels of country-carts in Sind to-day. Other two-wheeled vehicles are represented by bronze toys described below (p. 69), and from Chanhu-daro are terra-cotta models apparently of four-wheeled carts, with the front pair of wheels larger than the back pair.
