DEAR SIR,--Your letters of August 23d, 27th, 29th, and 30th, have all been received; the two last came yesterday. I observe that the merchants of New York and Philadelphia think that notice of our present crisis with England should be sent to the Straits of Sunda by a public ship, but that such a vessel going to Calcutta, or into the Bay of Bengal, would give injurious alarm; while those of Baltimore think such a vessel going to the Straits of Sunda would have the same effect. Your proposition, very happily in my opinion, avoids the objections of all parties; will do what some think useful and none think injurious. I therefore approve of it. To wit, that by some of the private vessels now going, instruction from the department of State be sent to our Consul at the Isle of France, to take proper measures to advise all our returning vessels, as far as he can, to be on their guard against the English, and that we now appoint and send a Consul to Batavia, to give the same notice to our vessels returning through the Straits of Sunda. For this purpose I sign a blank sheet of paper, over which signature the Secretary of State will have a consular commission written, leaving a blank for the name to be filled up by yourself with the name of such discreet and proper person as shall be willing to go. If he does not mean to reside there as Consul, we must bear his expenses out and in, and compensate his time. I presume you will receive this commission, and the papers you sent me through the Secretary of State, on the 8th. I approve of the orders you gave for intercepting the pirates, and that they were given as the occasion required, without waiting to consult me, which would have defeated the object. I am very glad indeed that the piratical vessel and some of the crew have been taken, and hope the whole will be taken; and that this has been done by the militia. It will contribute to show the expediency of an organized naval militia. I send you the extract of a letter I lately wrote to General Dearborne on the defence of the Chesapeake. Your situation will better enable you to make inquiries into the practicability of the plan than he can. If practicable, it is all-important.
