COCHIN-CHINA. M. Hedde has published a few notices of a visit to Turon in Annam in 1844, on his passage from Singapore to Macao.[102] He represents the country as altogether in a wretched, declining condition, misgoverned and beggared by despotic officers, presenting a painful contrast in its general prosperity with the Chinese empire. The present monarch is named Thieufri (or Yuen-fuh-siuen in Chinese) and succeeded his father Ming-ming or Minh-menh in 1841, but no improvement in the domestic or foreign administration of the government has taken place. Several Cochin-Chinese youth have been educated at Singapore, and the king purchased two steamers several years ago from the Dutch, but the natives probably were too little acquainted with the machinery and motive power to make the least use of them, as nothing has since been heard of them. The country is highly favored by its natural advantages and navigable rivers for maintaining a large population, but oppression on the part of the rulers and ignorance among the people, vitiate the sources of national prosperity. The port of Turon alone, is open in Annam for foreign trade, but no American vessels have been there for a cargo since Lieut. White's unsuccessful voyage in the Franklin in 1804. Capt. Percival of the U.S. ship Constitution anchored there in May, 1845, but no official account of his visit has been published, which if the rumors of his firing upon the town are true, is not strange. The Peacock and Enterprize also anchored there in 1836, but Mr. Roberts, the American diplomatic agent, was too ill to have any communications with the authorities. CHINA. The late war between England and China has directed the attention of other nations towards that empire in an unusual degree. Except the immediate details of the contest and the personal incidents connected with it, however, the works of those officers who have written upon that war, have not contained so much information as was expected by some, but quite as much as could be collected under the circumstances. The war was almost wholly a maritime one, confined to attacks upon cities and forts upon the coast and rivers, by both the army and navy, and few or none of the officers were acquainted with the language of the people, so that little information could be obtained from those natives whom suspicion or terror did not drive away. The region around Ningpo, Chusan and the mouth of the Yangtsz kiang, has been described with more minuteness than any other part of the maritime provinces; and the careful survey of the coast from Amoy to Shanghai, with the Chusan and Pescadore archipelagoes by Captains Collinson, and Kellet and others, has left little to be done for the navigator's benefit, in making known the hydrography of this part of China. The general topography of China is, however, but little better known now than it was at the close of the general survey of the Jesuits in 1714, and their maps form the basis of the best extant.
