Near the entrance of one of the castle-yards they met a couple that attracted their attention. It was a respectable-appearing citizen who had evidently partaken too freely of the cup that cheers and also inebriates, as his steps were unsteady, and he would have fallen to the ground had it not been for the assistance of his wife, who was leading him and guiding him in the way he should go. As the strangers went past him he raised his hand to his head; but Frank could not determine whether it was a movement of salutation or of dazed inquiry. The Doctor suggested that it was more likely to have been the latter than the former, since the Japanese do not salute in our manner, and the man was too much under the influence of the "sa-kee" he had swallowed to adopt any foreign modes of politeness. Sights like this are not unknown in the great cities of Japan, but they are far less frequent than in New York or London. The Japanese say that drunkenness is on the decrease in the past few years, owing to the abolition of the Samurai class, who have been compelled to work for a living, instead of being supported out of the revenues of the state, as formerly. They have less time and money for dissipation now than they had in the olden days, and, consequently, their necessities have made them temperate. [Illustration: SAKURADU AVENUE IN TOKIO.] For an Oriental city Tokio has remarkably wide streets, and some of them are laid out with all the care of Western engineering. In the course of their morning ride the party came to Sakuradu Avenue, which Fred recognized from a drawing by a native artist, who had taken pains to preserve the architecture of the buildings on each side with complete fidelity. The foundations of the houses were of irregular stones cut in the form of lozenges, but not with mathematical accuracy. The boys had already noticed this form of hewing stone in the walls of the castles, where some very large blocks were piled. They were reported to have been brought from distant parts of the empire, and the cost of their transportation must have been very great. Few of the houses were of more than two stories, and the great majority were of only one. Along Sakuradu Avenue they were of two stories, and had long and low windows with paper screens, so that it was impossible for a person in the street to see what was going on inside. The eaves projected far over the upright sides, and thus formed a shelter that was very acceptable in the heat of summer, while in rainy weather it had many advantages. These yashikis were formerly the property of Daimios, but are now occupied by the Foreign Office and the War Department. Inside the enclosure there are many shade-trees, and they make a cooling contrast to the plain walls of the buildings. The Japanese rarely paint the interior or the exterior of their buildings. Nearly everything is finished in the natural color of the wood, and very pretty the wood is too. It is
