We have received, through a channel which cannot be considered as authentic, the copy of a paper, styled ‘Additional instructions to the commanders of his Majesty’s ships of war and privateers, &c.’ dated at St. James’s, June 8, 1793. If this paper be authentic, I have little doubt but that you will have taken measures to forward it to me. But as your communication of it may miscarry, and time in the meanwhile be lost, it has been thought better that it should be supposed authentic: that on that supposition I should notice to you its very exceptionable nature, and the necessity of obtaining explanations on the subject from the British government; desiring at the same time, that you will consider this letter as provisionally written only, and as if never written, in the event that the paper which is the occasion of it be not genuine. The first article of it permits all vessels, laden wholly or in part with corn, flour, or meal, bound to any port in France, to be stopped, and sent into any British port, to be purchased by that government, or to be released only on the condition of security given by the master, that he will proceed to dispose of his cargo in the ports of some country in amity with his Majesty. This article is so manifestly contrary to the law of nations, that nothing more would seem necessary than to observe that it is so. Reason and usage have established that when two nations go to war, those who choose to live in peace retain their natural right to pursue their agriculture, manufactures, and other ordinary vocations, to carry the produce of their industry for exchange to all nations, belligerent or neutral, as usual, to go and come freely without injury or molestation, and in short, that the war among others shall be, for them, as if it did not exist. One restriction on their natural rights has been submitted to by nations at peace, that is to say, that of not furnishing to either party implements merely of war for the annoyance of the other, nor any thing whatever to a place blockaded by its enemy. What these implements of war are, has been so often agreed and is so well understood as to leave little question about them at this day. There does not exist, perhaps, a nation in our common hemisphere, which has not made a particular enumeration of them in some or all of their treaties, under the name of contraband. It suffices for the present occasion, to say, that corn, flour, and meal are not of the class of contraband, and consequently remain articles of free commerce. A culture which, like that of the soil, gives employment to such a proportion of mankind, could never be suspended by the whole earth, or interrupted for them, whenever any two nations should think proper to go to war.
