being wheeled backwards and forwards in wings from the centre, and into zigzag formations from central points, with a slow 'stamp-and-go' march, the spears being flourished with each motion and pointed high and low, and right and left, as in our bayonet exercise. The marshals regulated the movements of their respective lines with great accuracy, the one being retired directly the other advanced, so that the relative distance was never altered. After a time both parties suddenly assumed a sitting posture and exchanged howls of defiance, which grew fiercer and fiercer, until a simultaneous rush, as if to engage, finished the performance from which the representatives of barbaric warfare retired amid the hearty cheers of the representatives of the bayonet and rifle. [Illustration: A Daimio Retainer. (Native Drawing.)] Though most of the Daimios have enormous revenues, and are surrounded by men devotedly attached to them, the policy of the country so trammels their actions with formalities and espionage as to keep them in considerable subjection to the Tycoon; nor is even the privacy of their houses respected, for their families are retained in Yeddo, as hostages for their good behaviour, while they are absent in their principalities. As an occasional relaxation from the cares attendant on their high position, they avail themselves of a privilege called 'naiboen,' which enables them to share incognito in the pleasures and amusements of their countrymen. Those drawings and coloured representations of scenes connected with the higher classes which so largely engross the attention of Japanese artists, generally depict naiboen intrigues and adventures: these convey, however, a very exaggerated idea of the manner in which the Daimios conduct themselves on these occasions. [Illustration: Coolies carrying Norimon. (From Native Drawing.)] The family in the house-boat witnessing a pyrotechnic display in the bay of Yeddo, may be regarded as a faithful representation of a Daimio's party enjoying the naiboen. The great man in his light summer robe has apparently cast aside the cares of office, and seems thoroughly to enjoy the cool evening breeze and the society of his wives, only one of whom has a legal claim to that title, by right of which she takes precedence of the others. Of the two bonzes, or priests, in the stem of the boat, one, probably, is a member of the family, and the other its spy, for even naiboen excursions are not exempted from espionage: indeed the Japanese are so habituated to this custom that they generally regard it as a necessary check upon themselves. Naiboen excursions to the tea-houses are very frequent, notice being sent previously in order to insure proper accommodation and privacy: the latter precaution being principally taken on account of the ladies of the family, who never go beyond the palace except in a norimon guarded by armed retainers.
