(1360-61 A.D.) victorious and triumphant he came to Dehli, and after a short time he gave orders for an expedition to the river Salima, which is a river issuing from a large mound of sand and falling into the river Sutlej which they also call Satlaz. The Salima is also called the Sarsuti, and this river consists of two large streams which are always flowing, and situated between these two streams there is a high mound or dyke, and if this were dug through the water of the Sarsuti would flow into this stream, and it flows through Sihrind and Mansurpur and Samana. The Sultan gave orders for fifty thousand men with spades to be collected and to occupy themselves in digging through that barrier. Out of it they obtained many bones of elephants and human beings. Every bone belonging to the arm of a man was three gaz (in length). They were partly converted into remained bone dry as they were. That stream however could not be diverted, and in the meantime he made Sirhind and fourteen parganas into one district, which he put under the control of Ziaul Mulk Shamsu-d-Din Aburija, and ordered them to build a fort thereon and called it Firuzpur which is in fact Sirhind, and the Sultan from thence, went to Nagarkot whose Raja after a siege and some fighting came in and submitted and met with royal treatment.
