to make the inquiry so long desired, as to the probability of a common origin between the people of color of the two continents.  I have to ask the favor of you to procure me a copy of the above work of Pallas, to inform me of the cost, and permit me to pay it here to your use; for I presume you have some mercantile correspondent here, to whom a payment can be made for you.  A want of knowledge what the book may cost, as well as of the means of making so small a remittance, obliges me to make this proposition, and to restrain it to the sole condition that I be permitted to reimburse it here.

I enclose you a letter for the Emperor, which be pleased to deliver or have delivered:  it has some relation to a subject which the Secretary of State will explain to you.

Accept my salutations, and assurances of esteem and consideration.

LETTER XXX.—­TO THE EMPEROR OF RUSSIA

TO THE EMPEROR OF RUSSIA.

Washington, April 19, 1806.

I owe an acknowledgment to your Imperial Majesty, of the great satisfaction I have received from your letter of August the 20th, 1805, and sincere expressions of the respect and veneration I entertain for your character.  It will be among the latest and most soothing comforts of my life, to have seen advanced to the government of so extensive a portion of the earth, and at so early a period of his life, a sovereign, whose ruling passion is the advancement of the happiness and prosperity of his people; and not of his own people only, but who can extend his eye and his good will to a distant and infant nation, unoffending in its course, unambitious in its views.

The events of Europe come to us so late, and so suspiciously, that observations on them would certainly be stale, and possibly wide of their actual state.  From their general aspect, however, I collect that your Majesty’s interposition in them has been disinterested and generous, and having in view only the general good of the great European family.  When you shall proceed to the pacification which is to re-establish peace and commerce, the same dispositions of mind will lead you to think of the general intercourse of nations, and to make that provision for its future maintenance, which, in times past, it has so much needed.  The northern nations of Europe, at the head of which your Majesty is distinguished, are habitually peaceable.  The United States of America, like them, are attached to peace.  We have then with them a common interest in the neutral rights.  Every nation, indeed, on the continent of Europe, belligerent as well as neutral, is interested in maintaining these rights, in liberalizing them progressively with the progress of science and refinement of morality, and in relieving them from restrictions which the extension of the arts has long since rendered unreasonable and vexatious.
