meet the immediate exigency, where it is provided that collectors, marshals, and other officers shall “seize and detain _any vessel_ or any arms or munitions of war which may be provided or prepared for _any military expedition_ or enterprise against the territory or dominions of any foreign prince or state.”[36] It is something to forget these things; but it is convenient to forget still further, that, at the Crimean War, in 1854, the British Government, jointly with France, made another appeal to the United States, that our citizens should “rigorously abstain from taking part in armaments of Russian privateers, or in any other measure opposed to the duties of a strict neutrality”;[37] and this appeal, declared by the British Government to be “in the spirit of just reciprocity,” was answered on our part by a sincere and determined vigilance, so that not a single British or French ship suffered from any cruiser fitted out in our ports. And it is also convenient to forget no less the solemn obligations of treaty, binding both parties:-- “That the subjects and citizens of the two nations _shall not do any acts of hostility or violence against each other_, nor accept commissions or instructions so to act from any foreign prince or state, enemies to the other party; nor shall the enemies of one of the parties be permitted to invite or endeavor to enlist in their military service any of the subjects or citizens of the other party; _and the laws against all such offences and aggressions shall be punctually executed_.”[38] At the date of this treaty, in 1794, there was little legislation on the subject in either country; so that the treaty, in harmony with the practice, testifies to the requirements of the Law of Nations as understood at the time by both powers.
