Unutterable

The unutterable agony of the parents, the horror and confusion of all who were in the castle, the fury of contending passions between the friends of the different parties—passions augmented by previous intemperance—surpass description.

In the cities the quarters for the wealthier classes are not so sharply defined as with us, though the love for pleasant outlooks and beautiful scenery tends to enhance the value of certain districts, and consequently to bring together the wealthier classes. In nearly all the cities, however, you will find the houses of the wealthy in the immediate vicinity of the habitations of the poorest. In Tokio one may find streets, or narrow alleys, lined with a continuous row of the cheapest shelters; and here dwell the poorest people. Though squalid and dirty as such places appear to the Japanese, they are immaculate in comparison with the unutterable filth and misery of similar quarters in nearly all the great cities of Christendom. Certainly a rich man in Japan would not, as a general thing, buy up the land about his house to keep the poorer classes at a distance, for the reason that their presence would not be objectionable, since poverty in Japan is not associated with the impossible manners of a similar class at home.
