Mr. De Long to Mr. Seward.
Sir: I have the honor to inform you that previous to the Moorish minister having taken any active steps, the viceroy, Prince Muley Abbas, on hearing of the tumult at the American consulate on the 26th of February last, immediately, and of his own free voluntary act, sent his lieutenant governor with soldiers to suppress the mob, and with instructions to render me all the assistance in his power.
Not hearing from my government, I felt it my duty, upon the receipt of this information, to tender to the prince my thanks ; which I did in person and by letter, copy of which is herewith enclosed.
In my interview with him I spent over an hour, which time was unusual, but he detained me making inquiries about our civil war and the country generally.
The prince left next day for Tetuan, and from his camp near that place addressed me an autograph letter; a translation of which, made by one of the first oriental scholars in this country, is herewith enclosed.
The perusal of this document will, I trust, prove as satisfactory to my government as it is grateful to my feelings, and that it will tend to convince them that the statements so unscrupulously made by Mr. Layard, in the English Parliament, and reported in some of the European papers, were as unfounded as they were untrue.
I have the honor to be, sir, your most obedient and humble servant,
Hon. William H. Seward, Secretary of State.
