The sea is under no one’s dominion except God’s; it cannot by its very nature be appropriated; it is common to all, and its use, by the general consent of mankind, is common, and what belongs to all cannot be appropriated by one; nor can prescription or custom justify any claim of the kind, because no one has power to grant a privilege adverse to mankind in general. Grotius places navigation and fishing in the sea on the same footing, or rather he looked upon interference with the freedom of fishing as a greater offence than interference with navigation. With regard to imposing tribute on fishermen, he said that such as are reckoned among the Regalia are imposed not on the thing, that is the sea and the fishing, but on the person; and while it may be levied by a prince on his own subjects, it is not to be levied on foreigners, for the right of fishing everywhere should be free to foreigners, lest a servitude be imposed on the sea which it cannot bear. An action of this kind would be worse than the prohibition of navigation; it would be barbarous and inhuman. If any one, says Grotius, claimed jurisdiction and sovereignty on the great seas for himself alone against promiscuous use, he would be looked upon as one who was aiming at extravagant dominion; if any one was to keep others from fishing, he would not escape the brand of insane cupidity.[620] It is hardly possible to escape the suspicion, which was apparently shared by King James, as it was by many others, that Grotius in these sentences was aiming obliquely at England. Such strength of language about the right of free fishing in the sea was scarcely pertinent to his theme, for neither the Portuguese nor the Spaniards contested that right, and the Dutch did not fish in waters under their control. It would, on the other hand, be explicable if Grotius had got a hint of James’s intention with regard to the “assize-herring” (see p. 152), and we know that as early as the beginning of 1606 proposals were made for the formation of an English fishery society, with taxation of foreign fishermen, and that in the beginning of 1608 negotiations were on foot between the English Government and the Dutch Ambassador as to the “assize-herring.”[621]
