The Memoirs of Jahāngīr (Jahāngīrnāma) 45: The Jam of Gujarat.

45

When the royal tents were pitched on the banks of the Mahi, the zamíndár (called) Jam attended at Court. Having obtained the honour of kissing the ground, he presented fifty horses, 100 mohurs, and 100 rupees. His name was Jasa, and Jam was his title, which is held by every man who succeeds to the chiefship. He is one of the greatest zamíndárs of the province of Gujarat. His territory is bordered by the sea. He has always 5000 or 6000 horsemen; but in time of war he can collect 10,000 or 12,000. There are plenty of excellent horses in his territory, and a Kachi horse is sold at as high as 2000 or 3000 rupees. I bestowed a khil'at upon him.
