Accordingly I attended in Mr. Brooke's hall of audience on the following day, where I found collected all the chiefs, and a crowd of natives, many of them having already been informed that the said letter was a requisition for me to assist in putting down the hordes of pirates who had so long infested the coast.

They have more than three hundred war-prahus, and extend their ravages even to Banjarmassim; they are not subject to the government of Bruni (Borneo); they take much plunder from vessels trading between Singapore and the good people of our country. "It would be a great service if our friend would adopt measures to put an end to these piratical outrages. "We can present nothing better to our friend than a kris, such as it is. "20th day of Rahial Akhir, 1257." To which I sent the following reply:--
