The real character of the connection between Lewchew and Japan is not well ascertained. No Japanese officers are seen on landing, and the officers appointed to attend the people of the Indian Oak, exhibited the greatest alarm when a few were seen at a distance, while the party were taking a walk. The trade between the two countries is confined to the ports of Napa and Kagosima, between which the vessels of both nations pass; the junks from other parts of Japan are not permitted to resort to Napa, but it is not probable that the prince of Satzuma has the right of appointing the residents, or whatever authorities are sent thither. M. Forcade says there were from ten to fifteen Japanese vessels in the port, but when the American ship Morrison was there, in 1837, there were only five. Lackered-ware, grass cloth, sugar, and earthen-ware, are exported to Kagosima, and a great assortment of metallic articles, cloths, provisions, and stationery taken in exchange. The country in the vicinity of Napa, and towards Shudi, the capital, is highly cultivated, and the people appear to be as well clothed, and possess as many of the comforts and elegancies of life as their neighbors. They still retain enough of their own customs, however, to distinguish them from the Japanese, even if their physical appearance did not point them out as distinct. M. Forcade says that there is reason for supposing Christianity to have been implanted in Lewchew at the same time it was introduced into Japan, but Lewchew at that time seems to have been much less dependant upon Japan than subsequently; and it is not probable that much was done to proselyte its inhabitants. He mentions that a cross is cut on the end of the rampart where foreigners land, who are thus obliged to trample on this symbol; but no other visitors mention any such sculpture or custom. The landing place at Napa is a long stone jetty, stretching across the beach, which at low tide, prevents boats approaching the shore.

JAPAN.

This country has recently attracted increased attention on the part of commercial nations, and several foreign ships have lately appeared on the coasts, whose reception has only shown the vigilance of the authorities in taking every precaution neither to offend nor receive their unwelcome visitors. The Dutch and Chinese are still the only nations allowed to trade with the Japanese, and the news brought by the latter people of the troubles they have lately gone through with their foreign customers, has probably only more strongly convinced the siogoun and his ministers of the propriety of their seclusive policy. Nor is there much reason to doubt that the Chinese and Japanese have avoided the fate of the natives of Luçonia, Java, and India, by shutting out foreigners from free access and intercourse with their people, and owing to their seclusion, have remained independent to this day. The works of Siebold upon the natural history and political condition of the country and its inhabitants, are now slowly publishing in Paris, but with such luxury of execution as to place them beyond the reach of most persons who might be desirous to examine them. The visits of two American ships to the bay of Yedo, has directed the public eye again to the empire. The first was that of the whaler Manhattan, Captain Cooper, who was led to think of going into the port by having taken eleven shipwrecked men off a small island near the Bonin islands, in April, 1845, lying southeast of Nippon. As he was going north, he fell in with a water-logged junk from Nambu, laden with rice and fish, from which he received eleven more, and soon after made the eastern coast in the principality of Simosa. Here he landed two men, and proceeding towards Cape King, landed two more, who made their way to Yedo. Owing to north winds, he was blown off the coast twice, and when he approached the estuary leading to the capital, he was taken in tow and carried up to the anchorage. Interpreters came off to the vessel, who could speak English sufficiently well to carry on an imperfect communication, who informed Captain Cooper that his wants would be supplied, but none of his company allowed to land. A triple cordon of boats was placed around the ship, consisting of upwards of a thousand small boats, displaying numerous flags, and containing as many armed men as if the country was in danger of attack. The ship was visited by crowds of natives of all ranks, who behaved with great decorum while gratifying their curiosity, but no trade was allowed. Many officers of high rank came on board and examined the ship, and took an inventory of every article belonging to the rescued seamen, before they were allowed to land. The ship was gratuitously supplied with provisions and a few spars, to the value of about $500, but the captain was again and again enjoined not to return there on any account. When he inquired what he should do if he again came across the siogoun's subjects in like distress, and exposed to a cruel death, he was told, "leave them to their fate, or take them where the Dutch can get them." The men rescued from starvation and death, were, however, deeply sensible of the kindness which had been shown them. After a stay of eight or ten days, Captain Cooper was towed out of the port, and down the bay to the coast, and the last injunction was only a repetition of the first order, not to come again. This reception, though it presents no encouragement to hope for a relaxation of the policy, deemed by the siogoun at once his safety and his profit, is less likely to call for summary chastisement than the rude repulse the American ship Morrison received in 1837, when she entered the bay of Yedo on the same errand, and was driven away by cannon balls and armed gunboats.

Captain Cooper represents the country in this portion of it as clothed with verdure, and under a high state of cultivation. The proximity of the mountains in Idzu, produces constant showers, which covers the highest peaks with forests and shrubbery. Terrace cultivation is extensively practiced, and constant labor is demanded to supply subsistence to the dense population, who still at times suffer severely for want of food. The capital could not well be seen from the ship, and its enceinte was so filled with trees, that its dimensions could not accurately be defined. No towers or pagodas were seen elevating themselves above the dull monotony of the buildings. The harbor was covered with vessels, at anchor and moving about; some of them unwieldy, open-stern junks, designed for the coast trade, others light skiffs and boats, used for communicating with vessels in the harbor and the shore. The greatest part of the coasting trade centres at Yedo, owing to the large amount of taxes paid the siogoun in kind, and the supplies the princes receive from their possessions while they reside in the capital, both of which causes operate to develope the maritime skill of the people, and increase the amount of tonnage. The shortsighted policy which confines the energies and capital of a seagoing people like the Japanese, within their own shores is, however, less a matter of wonder than the despotic power which could compel them to stay at home two centuries ago, at a time when their merchants and agents were found from Acapulco to Bangkok.

The Japanese empire presents the greatest feudal government now existing, and on that account is peculiarly interesting to the student of political science. In some respects, the people are superior to the Chinese, but are inferior in the elements of national wealth and progress. They belong to the Mongolian race, but are darker than the Chinese, and not as tall, though superior in stature to the Lewchewans. They approximate to the Kamtschatdales in their square build, short necks, large heads, and short lower limbs. They are of a light olive complexion, but seldom exhibit a florid, ruddy countenance.

Among the articles obtained from the junk by Captain Cooper, was a map of Japan, including part of Yesso. It is four feet square, drawn on the proportion of less than one degree to two inches, and contains the names of all the places there is room for. It is cut on wood, and painted to show the outlines of the chief principalities; the relative importance of the places is shown by writing their names in different shaped cartouches, but from the space occupied by the Chinese characters, there is probably not one-tenth of all the towns inserted. The distances between the principal points along the coast are stated, and on some of the leading thoroughfares inland. The map is evidently the original of Krusenstern's "Carte de Nippon," published by the Russian Board of Longitude, and is drawn up from trigonometrical surveys. The degrees of latitude bear the same numbers as upon European maps; the meridians are reckoned from Yedo. The existence of such maps among the people indicates that a good knowledge of their own country is far more extensively diffused than among the Chinese, whose common maps are a standing reproach to them, while they have others so much more accurate. The coast from Cape King northward to Simosa, for the space of two degrees, was found by captain Cooper to be better delineated upon this map than upon his own charts. These seas present a fine field for hydrographic surveys, and it would greatly advance the security of navigation on the eastern shores of Asia, and redound to the honor of our own land, if the American government would despatch two small vessels to survey the seas and shores between Luçonia and Kamtschatka.

The visit of Commodore Biddle to the bay of Yedo, has added nothing to our knowledge of its shores. His polite dismissal, and the refusal of the government to entertain any commercial relations with the Americans, only add force to the injunction to captain Cooper the year before, not to return, and shows more strongly that while the Japanese rulers are determined to maintain their secluded policy, they wish to give no cause for retaliatory measures on the part of their unwelcome visitors, and mean to keep themselves as well informed as they can upon foreign politics. The subject of foreign intercourse between the two great nations of Eastern Asia and Europeans since it commenced three centuries since, is an instructive one; and the general impression left upon the mind of the candid reader, is that foreign nations have themselves chiefly to thank for their present seclusion from those shores, and the restrictions in their commerce. Rear-Admiral Cecille has also paid a visit to some part of Japan, quite recently, but met with no success in his endeavors to enter into negotiation.

The great object in view in making these attempts to improve the intercourse with Japan, is to find new markets for western manufactures. It is quite doubtful, however, whether the Japanese have many articles suitable for foreign markets. Their lackered-ware is exceedingly beautiful, but it would not be so prized when it became more common. Copper and tea would form the basis of exports, and perhaps some silk fabrics, but China furnishes now all that is wanted of them both, and can do so to any extent. Until a taste for such foreign manufactures, as woolens, cutlery, glass-ware, calicoes, &c., is created among them, and they are willing to adapt their own products to the tastes of their customers, it does not seem likely that a trade at all proportioned to the estimated population and riches of the country, would soon be established. The Japanese are afraid of the probable results of a more extended intercourse, and deem it to be the safest course to run no risks; and if they read the pages of their early intercourse with the Portuguese, Spanish and Dutch, they must feel they would run many serious risks by granting a trade. If the siogoun and his advisers could be rightly informed, however, there are grounds for believing the present policy would be considerably relaxed.

Learning is highly honored in Japan, and books are as cheap and common as in China. The written language is a singular and most difficult mixture of Chinese characters, with the syllabic symbols adopted by the Japanese, rendering its perusal a great labor, more so than that of Chinese, because Chinese must first be mastered. The spoken language is polysyllabic and harmonious, and possesses conjugations, tenses, cases, &c., to facilitate its perspicuity, and increase its variety of expressions. The arts in which they chiefly excel are in the manufacture of silken and linen goods, copper-ware, lackered-ware, porcelain and basket work. Their cutlery is despicable, and the specimens of their carving, which are seen abroad, do not equal those produced by the Chinese. Agriculture is pursued on much the same system as in China—minute subdivision of the soil and constant manuring, together with frequent watering. Rice and fish are the staples of food; vegetables are used in great abundance, but meats only sparingly. The habits and sports of the people are influenced so much by the peculiar notions attending a feudal society, such as adherence to the local prince, and maintenance of his honor, wearing coats of arms, privileged orders, and hereditary titles, that there is little similarity in the state of society in Japan and China, notwithstanding a similar religion and literature. The Japanese were called the Spaniards of the East by Xavier, and the comparison is good at this day. They have, perhaps, more genius and imagination than the Chinese, but are not as peaceable or industrious.

General view of the languages of the Japanese, Coreans, Chinese and Cochinchinese. The four nations here briefly noticed; viz., the Japanese, Coreans, Chinese and Cochinchinese, have been collectively called the Chinese language nations, from the peculiar relations and connections they have had through the medium of that language. The relation has throughout been one of a literary character, fostered to some extent by religious prejudices, but depending chiefly for its permanence and extension upon the superiority of the writings of the Chinese. It is, in some respects, without a parallel in the history of man. While European languages have all been indebted for many of their words to the two leading ancient tongues of that continent, their bases have been diverse, and the words they have imported from Greek and Latin have undergone various changes, so much so as sometimes hardly to be recognized. This is not the case with these four nations of eastern Asia. They have all adopted the characters used by the leading nation without alteration, and with them, of course, have to a very great degree, taken her authors, her books, her knowledge and her opinions, as their own.
