"they afterwards conform to the express regulations of their "Prize Acts" (1). Similar expressions abound in the luminous expositions of International Law which these judgments afford. XLIV. The Law of Nations has received continual accessions and improvements since the first cultivation of it in the Christian world; not only have evil customs been abrogated, but the rigour of many ancient customs has been softened and relaxed in their application, without any departure from the principle on which they were founded. This effect is happily described by Lord Stowell; when speaking of contraband articles found on board a neutral vessel, he says, "I do not "know that under the present practice of the Law of "Nations a contraband cargo can affect the ship. By the "ancient law of Europe, such a consequence would have "ensued; nor can it be said that such a penalty was unjust, "or not supported by the general analogies of law, for the 66 owner of the ship has engaged it in an unlawful commerce. "But in the modern practice of the Courts of Admiralty "of this country, and I believe of other nations also, a “milder rule has been adopted” (m). On the other hand, usage has decided that many things are contraband in naval war concerning which there had formerly been much dispute. Valin says, honestly and boldly, in his Commentaries, "De droit ces choses sont de contrabande aujourd'hui et "depuis le commencement de ce siècle, ce qui n'était pas "autrefois néanmoins" (n). There must be, however, a reciprocity (o) in the conduct of the nation demanding from another nation the privilege of these mitigations introduced by usage into the ancient Law; and a nation may be estopped (1) 1 C. Rob. Adm. Rep. p. 61. The Mercurius, 1 C. Rob. Adm. Rep. p. 82: "Under the modern law of nations." The Maria, Ib. 371 a: 66 According to the modern understanding of the law of nations."

Such is the influence of universal usage, that it will in some measure affect even the stipulations of a treaty made long prior to the commencement of that usage, and at a time when the law, which has been since settled, was in a state of fluctuation and controversy (p). In 1654, a treaty was entered into between England and Portugal, by which, among other things, both countries mutually bound themselves not to suffer the ships and goods of the other taken by enemies, and carried into the ports of the other, to be conveyed away from the original owners or proprietors. "Now, I have no scruple in saying" (observes Lord Stowell, in 1798)," that this is an Article incapable of "being carried into literal execution, according to the modern "understanding of the Law of Nations, for no neutral country can interpose to wrest from a belligerent prizes "lawfully taken" (q). This is, perhaps, the strongest instance that could be cited, of what civilians call the "consuetudo obrogatoria" (r). XLVI. So the establishment of Courts of the Law of Nations in all civilized countries in time of war, is an institution introduced by civilized usage, and binding upon all civilized countries. Neutral Nations in time of War have now no right (s), when they are injured, to exact compensation from the countrymen of the aggressors (t), though the Barbary States were said by Lord Stowell to do so, " under a Law of Nations (p) The Maria, 1 C. Rob. Adm. Rep. pp. 371-373. (q) The Santa Cruz, 1 C. Rob. Adm. Rep. pp. 49, 64. See also vol. ii. p. 732, of Sir Leoline Jenkins's Works. (r) Savigny, System des Römischen Rechts, b. i. 195.

Neither in time of Peace are Nations entitled to have recourse to Reprisals, until reparation for the injury sustained has been formally asked and denied, both of the proper tribunal, and of the government, in re minime dubia. These points, however, will receive a fuller discussion in another part of this work. (u) The Kinder Kinder, 2 C. Rob. Adm. Rep. p. 88. CHAPTER VI. HISTORY-TREATIES. XLVII. SUCH being the influence of usage upon International Law (a), it becomes of importance to ascertain where the repositories, and what the evidence, may be of this great source of International Law. XLVIII. (1.) In the enumeration of these, History, unless the term be too general, necessarily takes the first place. It supplies, according to Grotius, both example and authoritative judgments—of which the latter owe their weight to the general acceptance which they have obtained, whilst the former are more or less valuable according as they are more or less derived from epochs and nations more or less entitled to universal respect (b). It is scarcely necessary to guard against the error which (a) "Quamquam enim nec sit exemplis judicandum, et aurea ea dicitur Justiniani lex, ab exemplis tamen duci probabilem conjecturam certum est, et in dubio judicandum imo est exemplis ; et cum itum in consuetudinem est. Neque enim mutare decet quæ certam observantiam semper habuerunt, et firmius judicium creditur, quod plurimorum sententiis confirmatur."-Albericus Gentilis, lib. i. c. ii. De Jure Belli. (b)" History," Hume observes," the great mistress of wisdom, furnishes examples of all kinds; and every prudential as well as moral precept may be authorised by those events which her enlarged mirror is able to present to us."-Hist. of England, vol. vii. p. 150. Grot. Proleg. 8. xlvi.: "Historiæ duplicem habent usum, qui nostri sit argumenti: nam et exempla suppeditant et judicia. Exempla, quo meliorum sunt temporum ac populorum, eo plus habent auctoritatis; ideo Græca et Romana vetera cæteris prætulimus. Nec spernenda judicia, præsertim consentientia; jus enim naturæ, ut diximus, aliquo modo inde probatur; jus vero gentium non est ut aliter probetur." The Flad Oyen, 1 C. Rob. Adm. Rep. p. 141. Grotius, in another part of his work, denounces-that instances recorded in History, merely by virtue of being so recorded, constitute precedents of International Law (c). History is a record of the injustice, evil passions, and folly, as well as of the justice, virtues, and wisdom of Nations. The necessities of the epoch in which Grotius wrote left him little or no choice in selecting his examples and precedents chiefly from the antiquity of Greece and Rome. This is not the case with his successors; they have far ampler and far apter materials. But the edifice is not the weaker for the breadth and depth of the classical foundations laid by the first architect; and the principle which guided him is in this, as in most other instances, most valuable to the later and, in spite of their advantages, inferior builders. XLIX. (2.) Secondly, the consent of Nations is evidenced by the contents of Treaties, which for this, as well as for other reasons, constitute a most important part of International Law (d). L. Upon this point there is one observation which merits, from its importance, precedence over all others. It is this: No treaty between two or more Nations can affect the general principles of International Law prejudicially to the interest of other Nations not parties to such covenant; at the same time, the contracting parties (e) may introduce (c) "Solet et illud quæri, an jure talionis interfici, aut male tractari legatus possit ab eo veniens, qui tale quid patraverit. Et sunt quidem ultionis talis exempla in historiis satis multa: sed nimirum historiæ non tantum quæ juste, sed et quæ inique, iracunde, impotenter facta sunt, memorant."-Grot. 1. ii. c. xviii. 7. (d)" All this body of old conventions, composing the vast and voluminous collection called the Corps diplomatique, forms the code or statute law, as the methodized reasonings of the great publicists and jurists form the digest and jurisprudence of the Christian world. In these treasures are to be found the usual relations of peace and amity in civilized Europe."-Letters on a Regicide Peace, Burke, Works, vol. ix. p. 235.
