that the right of visiting and searching merchant ships upon the high seas, whatever be the ships, whatever be the cargoes, whatever be their destination, is an incontestable right of the lawfully commissioned cruisers of a belligerent nation.... This right is so clear in principle that no man can deny it who admits the legality of maritime capture, because if you are not at liberty to ascertain by sufficient inquiry whether there is property that can be captured, it is impossible to capture. On this another rule has been grafted which is suggested by the enunciation of the law as to the right of search. That right _must_ be exercised for the very same reason that the right has been allowed, for otherwise you do not know whether you have the right to seize. From the _right of search_ has therefore developed the _duty to search_; and it is the omission to recognise this duty that has plunged the German Admiralty into its piratical career. _The Doctrine of Continuous Voyages_ But the heart of the neutral merchant is desperately ingenious, especially when his country is contiguous to the theatre of war, and no sooner had he obtained the inch to which practical considerations made him appear to be entitled than he developed it into an ell of his own imagining. He argued thus: A neutral vessel bound to an enemy port is liable to detention, because the presumption is that she has cargo for the enemy, and that her cargo is probably contraband; the presumption also is that cargoes on board a vessel bound for a neutral port are not destined for the enemy, even though they may be contraband; nothing easier than to bring them across the sea in a neutral vessel with a neutral destination; all that remains to be done is to pass them on to the belligerent, either transhipping them into another vessel and sending it down the coast, out of the way of the attentions of the enemy’s cruisers, or better still, if the neutral and belligerent countries are contiguous, by rail across the border. And the best of the plan is that the shipper on the other side of the water, say some innocent merchant in copper in the United States, need know nothing about it, so that if by chance the cargo does get seized he will do all the shouting.
