The appearance of things between this country and Great Britain, and the Emperor and the King of Prussia, has been so long hostile, without an open rupture, that it is not easy to say when either war will begin. The King of Prussia has found it so necessary to cultivate the aid of Hanover, Hesse, Brunswick, &c. that he has declined receiving your deputy, or following the example of France as he promised. It remains therefore to try the Empress, who, independent of the present crisis, was much less inclined to our cause. It seems to be the settled system of northern politics, that if a war should happen, the Empress of Russia will assist the King of Prussia, as far as the Porte will permit her. In this country, the appointment of Marechal de Broglio commander of the army on the sea coast, and the Duc de Chartres, son to the Duc d’Orleans and Prince of the blood, going on board the fleet at Brest, announce designs of some dignity and magnitude. I am of opinion, with our colleague Mr Adams, that it would be better for the public, that the appointment of your public ministers were fixed, instead of being left at large, and their expenses indefinite. From experience I find the expense of living in that character cannot well be less than three thousand pounds sterling a year, which I believe too is as little as is allowed to any public minister above the rank of a consul. If left at liberty, I conceive that most persons will exceed this sum. Neither do I perceive any adequate advantage to be expected from having more than one person at each Court. When things take a more settled form, there will be little need of that check, which is the chief utility of it at present. The mixing powers too, and vesting them in several persons at the same time, give ground for disputes, which are disgraceful as well as detrimental to the public. This has been much experienced in the case of the commercial agents, and the agent of the Commissioners, who have been clashing and contesting till the public business was almost entirely at a stand. For the present, however, we have settled this matter, by directing all commercial business to be put into the hands of those appointed by the commercial agent, till the pleasure of Congress is known. Two more ships have been lately sent to Newfoundland, and two to the Mediterranean, which, with thirteen detached under Admiral Byron to reinforce Lord Howe, leave seventeen of the line and eight frigates for Admiral Keppel, and these very ill manned. I have exceeding good information, that their plan of operations for America is as follows. General Howe is to evacuate Philadelphia, sending five thousand of his troops and two ships of war to Quebec; the rest of the troops with the fleet are to return to Halifax, where the latter being joined by Admiral Byron will, it is presumed, maintain a superiority in those seas over the allied fleet.
