Ko boo shio boonio.--The military school where drill exercise, the use of weapons of war, fortification and military tactics generally, are taught to young officers. There are three officers over the establishment, but many teachers of the different branches. The school is in Owo ngawa matchi or street in Yedo. Artillery is taught near the garden of the Shiogoon at Hama go teng. Sword-practice with sticks (kenjits) is a favorite amusement with young officers. They have sticks with basket guards, with which they practice. Before beginning, each puts on an iron wire grating over the head, a bamboo-and-leather belt around the chest, and bamboo guards for the arms with gloves. Yet with all this one is sometimes severely handled. The sword is long, two-handed, sharp on one edge and at the point, and for about two inches from the point on the back; so that they either cut or thrust, and aim at cutting the neck with a back cut. They are very dexterous at the use of this weapon, whether against a sword or a bayonet or spear. Practice with the rifle is also very common in the government schools, and in the grounds of Daimios about Yedo. There is a large parade ground or open country to the back of Yedo for the use of the military, called Hiro. Naka kawa bansho.--An office for the examination of boats coming from and passing to the interior by the communicating branch of the river--the Naka gawa. Upon this stream boats can go to the provinces on the northwest, north and east of Yedo. Besides these there are officers who have charge of the Shiogoon’s barges and boats. There are officials whose duty is to examine into alleged encroachments by Daimios in Yedo upon the roads, streets, rivers, or sea. The superficial quantity of land as gardens that an officer may hold in Yedo is regulated by his official income. (One tsubo equals thirty-six square feet.) An income of from 300 to 900 koku may have 500 tsubo, 18,000 square feet; 1,000 to 1,900 koku may have 700 tsubo, 25,200 square feet; 2,900 koku may have 1,000 tsubo, 36,000 square feet; 4,000 koku may have 1,500 tsubo, 54,000 square feet. And so on up to 150,000, whose allotment is 7,000 tsubo, or about 252,000 feet square. There are sword-keepers of the Shiogoon, and also keepers of the books or library, and a keeper of the presents, gifts, or tribute paid by each Daimio. Gifts as tribute are being received daily, and are regulated by order. But frequently handsome presents are voluntarily made by Daimios, perhaps in some cases for favors to come. For instance, Owarri is ordered to present to the Shiogoon upon the first month, third day, congratulatory cakes. Upon the third and seventh months a large noshi--symbol of a present with a piece of dried fish--with paper and two tubs of wine. On the 18th of the fourth month, fish; and again in the same month, A-ï, a fresh-water fish, considered a delicacy. On the fourth and eighth months, the same fish preserved in vinegar.
