Eight years later it was England that was carrying on a struggle for the principle of freedom of the seas. Modern research has established beyond any reasonable doubt that the immortal Jenkins did actually have an ear sliced off by a Spaniard who was searching his ship for smuggled goods, and that the tale was not a fabrication of the Opposition that desired to force Walpole to plunge England into war. The Opposition certainly recognized the recruiting value of the incident. "The tale of Jenkins' ear will raise us troops enough!" exclaimed one member on the floor of the House of Commons. Whether or not Jenkins commended his soul to God and his cause to his country, his country embraced his cause as that of the freedom of British commerce from search by Spaniards in time of peace. The British vessels searched were usually smugglers, but the British public was not interested in the right of Spain to safeguard her monopoly of trade with her colonies; they objected to search and to the contention that British ships must not be found in American waters outside the straight path between England and her colonies, and they besieged the doors of Parliament with the slogan: "A free sea or war!" And so was fought the war of Jenkins' Ear, which might have been avoided had it not been for the powerful influence, both with the people and with Parliament, of the South Sea Company; and which did nothing toward settling the point in controversy. Thus far the principle of freedom of the seas had been invoked in connection with efforts to preserve for the benefit of a whole nation or of favored groups of nationals, all access to the trade and resources of certain regions. During the wars for colonies and commerce which arose from these efforts, the principle was brought forward against interruption of commerce in time of war. In the days when privateering was a recognized adjunct of maritime, warfare, commerce-destroying was reduced to a science that only the last three years have rivalled. The seizure as contraband of anything which might help the enemy to prolong the struggle, and the confiscation of cargoes of neutral ships, on the ground that part of the cargo belonged to the enemy, caused endless international complications. Treaties of peace began to contain provisions designed to render less burdensome these rights claimed by belligerents. The first step toward anything like international agreement was taken in the treaties of Utrecht in 1713. By these treaties contraband was limited to articles directly useful in war, exclusive of foodstuffs; enemy goods on neutral ships were protected on the principle later reduced to a formula, as "free ships, free goods"; and the method of visit and search was regulated. These arrangements did not outlast the peace, but many later treaties renewed, and some developed more fully, these restrictions, which were naturally more popular with neutral powers and with powers possessing small navies,
