The military, governing and literary class in Old Japan, the retainers of the Daimios. They were the highest of the four classes into which the nation was divided, and formed in fact the gentry of Japan.

A treaty between Spain and the French Directoire, signed in 1794, providing that either Power, in the case of one or the other being attacked, should provide for its ally material aid in the shape of fifteen ships of war, and a land contingent of 24,000 men. This provision, however, was not to apply to the war in which France was then engaged, excepting only in the case of England, against whom Spain, having grievances of her own, was prepared to take up arms at once. San Juan Arbitration. The question as to the ownership of the island of San Juan, lying between Vancouver and the American coast, arose out of the wording of the Treaty of Ghent in 1818, by which instrument the middle of the channel between Vancouver and the mainland was fixed as the boundary. San Juan being in the middle of the channel, the question of ownership was a doubtful one, but the arbitrators, in 1872, decided in favour of the United States. San Stefano, Treaty of. A treaty signed by Russia and Turkey, at the close of the Russo-Turkish War in 1878. By its provisions the whole of the Christian provinces of Turkey were rendered practically independent, while Bulgaria was erected into an important state with a port on the Ægean Sea. England refused to recognize this treaty, and eventually Russia agreed to submit it to a European Congress, which was held at Berlin in the autumn of the same year. Sanctuary. The right claimed by the Church of affording protection to criminals who took refuge in churches and other consecrated precincts. In some cases these refugees from justice were enabled to set the law at defiance for years, by keeping within these precincts. Some of the most notorious of these cities of refuge were abolished by Act of Parliament in 1697, but it was not until the reign of George I that the last of them, the Sanctuary of St. Peter’s, Westminster, ceased to exist. Sand River Convention. A treaty signed in 1852 by which the British Government recognized the right of the emigrants beyond the Vaal to manage their own affairs, and govern themselves in accordance with their own laws. Other clauses of the Convention provided for free trade, except in arms, arbitration in any dispute that might arise in respect of the boundary over the Drakensberg, extradition, and free passage of the Vaal for all except criminals and fugitive debtors. The British Government further disclaimed the right to make treaties with native tribes north of the Vaal. Sandomierz, Confederation of.
