So the word donation is sometimes used to signify a transfer, according to the nature of the business. In the same manner too the word arms, which in general signifies military instruments, is sometimes applied to troops, and may be taken in either sense, according to the particular occasion. Every interpretation must be given according to the intention understood. Thus the promise of a free passage given upon the evacuation of a town, implies also that the troops shall pass without molestation. If a number of ships are to be given up, perfect and not mutilated ships are meant. And in all similar cases a similar judgment must be formed according to the natural tenor of the words. VI. Another source of interpretation is derived from the consequences, especially where a clause taken in its literal meaning would lead to consequences foreign or even repugnant to the intention of a treaty. For in an ambiguous meaning such an acceptation must be taken as will avoid leading to an absurdity or contradiction. The cavil of Brasidas therefore is highly abominable, who, promising that he would evacuate the Boeotian territory, said he did not consider that as Boeotian territory, which he occupied with his army; as if the ancient bounds were not intended, but only what remained unconquered, an evasion, which entirely annulled the treaty. VII. From the circumstances or context another source of interpretation is derived. No inconsiderable light may be thrown upon the meaning of an expression from the circumstance of its being used by the same person to express the same intentions on other similar occasions, and from its relation to what goes before, and what follows the place, where it stands. For in all doubtful cases, we have reason to suppose that the contracting parties mean to be consistent with their former opinions and intentions. Thus in Homer, in the agreement between Paris and Menelaus, that Helen should be given up to the conqueror, when compared with what follows, it is evident that by the conqueror is meant the combatant, who killed the other. This rule of interpretation, Plutarch illustrates by the conduct of judges, "who passing by what is obscure rest their decisions upon clear and unambiguous points." VIII. As to the motives, which are sometimes taken for a rule of interpretation, there may be other substantial ones, besides those immediately expressed, for the passing of a law or the making of a treaty. Yet the strongest conjecture is that which arises from certain proof that the will was actuated by some reason, operating as a sole and sufficient motive. For there are frequently MANY motives, and sometimes the will is influenced by its own choice independent of any other reason. In the same manner a grant made, in contemplation of a marriage, will be void, if the marriage never takes place.
