March this important treaty was signed by Mr. Seward on the part of the United States and by Mr. de Stoeckl on the part of Russia. Few treaties have been conceived, initiated, prosecuted, and completed in so simple a manner, without protocol or despatch. The whole negotiation is seen in its result, unless we except two brief notes, which constitute all that passed between the negotiators. These have an interest general and special, and I conclude the history of this transaction by reading them. “DEPARTMENT OF STATE, WASHINGTON, March 23, 1867. “SIR,--With reference to the proposed convention between our respective Governments for a cession by Russia of her American territory to the United States, I have the honor to acquaint you that I must insist upon that clause in the sixth article of the draft which declares the cession to be free and unincumbered by any reservations, privileges, franchises, grants, or possessions by any associated companies, whether corporate or incorporate, Russian or any other, &c., and must regard it as an ultimatum. With the President’s approval, however, I will add $200,000 to the consideration money on that account. “I avail myself of this occasion to offer to you a renewed assurance of my most distinguished consideration. “WILLIAM H. SEWARD. “MR. EDWARD DE STOECKL, &c., &c., &c.” [TRANSLATION.] “WASHINGTON, March 17 [29], 1867. “MR.
