Mr. Orr: Permit me to correct an error in your editorial remarks of the 17th ins!, noticing the arrival of my mountain expedition at St. Louis. It appears from that statement that I met .a party of British traders West of the Rocky Mountains, in the year 1825, who had with them two hundred thousand dollars worth of fur-. I saw some of the men who had been of the party alluded to, after they had detached themselves from if, but did not see Mr. Ogden, (the partizan) or any of the men who remained with him. I was informed, however, that they had ab'out six hundred pounds of beaver fur with them at that time, and that, in tire course of several hunts which they made upon our territory West of the R cky Mountains, they had taken about eighty-five thousand beavers, say 150,000pounds: worth about six hundred thousand dollars.-Some of the American hunters who were then, and others who had been in my employ, went to the British camp, which consisted of about sixty men in the service ot the Hudson Bay Company. The circumstance which produced this visit had nearly led to serious consequences. Messrs. Jedediah S. Smith, William L. Sublette, and several others of the American p^irty, intelligent youug men, of strict veracity, had visited the British camp, and reported to their comrades that the British flag had been repeatedly hoisted during their stay there. The Americans, indignant at such impertinence, and understanding, too, that the British camp was wiih-in eight mi'es of them, resolved to proceed to the place, and tear down the flag, even at the risk of their lives. Twenty-two of them, with the American flag hoisted, advanced to the spot, but no British flag was to be seen. Thev made known their business to Mr Ogden, and protested, in threatning language, against a recurrence of the same insult offered them ; they also required of Mr. Ogden to move his party from that vicinity without delay. Mr. O. first hesitated, calling upon his men for protection, but ultimately finding there would probably be much danger in delay, he lost no time in getting under way, and has kept a respectful distance ever since. At the time of this occurrence I was descending the Rio Colorado of the West, but shortly after turned and joined the party of American hunters, from whom I received the above account. Yours, dec.W. H. ASHLEY.
