Hence the instructions to Commodore Perry covered broad ground, and his letters of credence conformed to his instructions. If he found the Japanese disposed to abandon, at once and forever, their deliberately adopted plan of non-intercourse with foreigners (an event most unlikely), his powers were ample to make with them a commercial treaty as wide and general as any we have with the nations of Europe. If they were disposed to relax but in part their jealous and suspicious system, formally to profess relations of friendship, and, opening some only of their ports to our vessels, to allow a trade in those ports between their people and ours, he was authorized to negotiate for this purpose, and secure for his country such privileges as he could, not inconsistent with the self-respect which, as a nation, we owed to ourselves. It must not be forgotten, in the contemplation of what was accomplished, that our representative went to a people who, at the time of his arrival among them, had, both by positive law and usage of more than two hundred years, allowed but one of their harbors, Nagasaki, to be opened to foreigners at all; had permitted no trade with such foreigners when they did come, except, under stringent regulations, with the Dutch and the Chinese; were in the habit of communicating with the world outside of them at second-hand only, through the medium of the Dutch who were imprisoned at Dezima; and a people who, as far as we know, never made a formal treaty with a civilized nation in the whole course of their history. There were but two points on which the Commodore's instructions did not allow him a large discretion to be exercised according to circumstances. These were, first, that if happily any arrangements for trade, either general or special, were made, it was to be distinctly stipulated that, under no circumstances and in no degree, would the Americans submit to the humiliating treatment so long borne by the Dutch in carrying on their trade. The citizens of our country must be dealt with as freemen, or there should be no dealings at all. The second point was that, in the event of any of our countrymen being cast, in God's providence, as shipwrecked men on the coast of Japan, they should not be treated as prisoners, confined in cages, or subjected to inhuman treatment, but should be received with kindness and hospitably cared for until they could leave the country.
