The return of a company of mountain traders to the settlements presents an opportunity for writing which I feel much inclined to embrace. We are now between 2 and 300 miles west of Independence, on the Blue river, a tributary of the Kansas, in good health and spirits. I regret to say that a division has taken place in the company, in consequence of the number of cattle driven by some, those having no cattle refusing to stand guard over stock belonging to others. The result of all this was that Capt. Burnett resigned command of the company, and the commander, in accordance with our regulations, ordered a new election, and so altered the by-laws that the commander should be called colonel, and also authorized the election of 4 captains, and 4 orderly sergeants. The cattle party selected myself as their candidate, those opposed selected Mr. Wm. Martin, an experienced mountaineer. There being a majority in opposition to the cattle party, Mr. Martin was elected, and a division of the company ensued. About 50 wagons, with those who had large droves of loose cattle, now left, with a general request that all in favor of traveling with them should fall back. I was particularly solicited to leave Martin's party, but as it would travel much the fastest, and Col. Martin was a very clever fellow, I declined. The new company, it is expected, will be commanded by Capt. Applegate. Our roads, since leaving the settlements have been very fine, except within the last few days, during which period they have been almost impassable in consequence of the tremendous rains, but they are again improving. We have had no trouble with the Indians, with the exception of horse and cattle stealing, and this business they have carried on pretty lively. I had a very fine mule and an ox stolen from me on the Kansas river, and we lost in all some 8 or 10 head of horses and mules. I believe there is not a case of sickness in camp, though old Mr. Stout, from Iowa, has a violent swelling in his eyes. Tell the boys from Iowa to come on with all the cattle and sheep they can get, and a company large enough to drive them. Truly yours, etc., M. M. M. [MCCARVER]. P. S.--My friend, Mr. Henry Lee, from Iowa, has just been elected Capt. of one of the divisions. While writing, news has been brought in of the discovery of a dead Indian about one mile from this place, and freshly scalped, and nearly all the company have gone to see him. He was shot with arrows and is supposed to be a Pawnee, killed by a party of the Kansas Indians whom we met the other day, consisting of 200, with fresh scalps and fingers, which they said had been taken the day before. * * * * * _Republican_, Friday, September 6, 1843.
