Many big iron guns have been found in different parts of Bengal, notably at Dacca, Murshidabad, Bishnupur and other places. A gigantic gun of hammered wrought iron was found at Dacca, which contained 234,413 cubic inches of the metal and weighed approximately 30 tons. The weight of an iron ball from this gun was found to be about 465 pounds. But the gun has disappeared now, having fallen into the river long ago, together with the bank on which it was placed. It is stated that this gun was mentioned under the name of *Kaley Khan* by the Venetian traveller Manucci in the list of big cannons possessed by the Moguls in the 17th century.
