“ Meantime, the Dominican Republic has suffered scarcely less, from its own disorders and the attacks of its Haytian neighbors. In 1861 it was surrendered by a provisional government to Spain, but recovered independence three years later. Soon afterwards one of its parties sought annexation to the United States, and in 1869 the President of the latter republic, General Grant, concluded a treaty with the Dominican government for the cession of the peninsula of Samana, and for the placing of San Domingo under American protection. But the Senate of the United States refused to ratify the treaty. ”
