As on the 19th January last, the port of Kanagawa was closed by a naval engagement being fought within its treaty limits, and with the view of preventing a repetition of similar infringements of the treaty between the United States and Japan, notice is hereby given to whom it may concern, and for the better observance of strict neutrality by the United States, that any hostile encounter, or even attempt to that effect, within the ten ri treaty limits of Kanagawa, on the sea or on land, by the forces of either party to the civil war now existing in Japan, will be considered a deliberate infringement of the said treaty, and as such must expect to meet with a decided expression of the displeasure of the United States.
