The Rajah of that place had one thousand elephants and two laks of infantry in his service. Riding horses are not available. Between the north and the west of Bengal, pointing more towards the north, is the province of Kuch Behar. Its length from east to west, from the beginning of Parganah Bhitarband, which is included in the conquered provinces, to Patagaon, which is the limit of the tract of the Murang, is 55 kos, and its breadth from south to north, that is, from Parganah Najhat, which is included in the conquered country, to Pushakarpur, which adjoins Khontaghat, is fifty kos. This tract of country, in point of the sweetness of its water, and mildness and salubrity of its air, and of Baghdad and Basorah; and it would seem it was this commercial Musalman activity combined with superior martial and moral qualities that paved the way for Musalman domination throughout Bengal. Subsequently in the reign of Ghiasuddin Tughlak Shah, we find the Bengal Musalman Kingdom has grown so extensive and unwieldy, that we find him separating Behar from Bengal, and placing it under an independent Governor, whilst Bengal itself for purposes of convenient administration was divided into three different sections, viz.: (1) Diyar-i-Sunargaon, comprising Eastern Bengal, (2) Diyar-i-Satgaon, comprising Western Bengal, and (3) Diyar-i-Lakhnauti, comprising Northern and Central Bengal.
