INDIAN WAR- Information of hostile designs on the part of the Pawnee Indians was published sometime since. We learn now, says the Missouri Republican, from Major Hamtramck, who has arrived in this city from his Agency in the Osage Nation, that the news of the successful operations of the Camanches and Pawnee Picks, on the Santa Fe Road, had been spread through the neighboring tribes, and aroused the whole to some daring action. Runners had been passing between the Camanches, Arapahos, Pawnee Picks, and Kiamechis, for the purpose of spreading the excitement, maturing plans and forming a concentration of forces. It is supposed they will watch the Santa Fe Road, and in the event of finding nothing on it, our frontier may suffer. Major Hamtramck is of opinion, from evidence in his possession, that Mr. Means of Franklin was killed, and his companions robbed by the Pawnee Picks. General Atkinson has, we understand, received orders to afford protection to our frontiers. The Osages have volunteered the services of from 800 to 1000 warriors which the government have accepted in the event of the Generals receiving an auxiliary force of Osages. The Osages are disciplined in that Pawnee mode of warfare, and intimately acquainted with the topography of their country.
