THIRD EXPLORING TOUR TO THE PACIFIc.- The expedition to the Rocky Mountains under com niand of Capt. J. c. Fremont of the United Stale, amy, being the third exploring tour of that officer
 left Wesipert the 26th ult Capt. Fremont is assisted by two junior officers of the Topographica corps and employs eight The design of this expedition IS 10 complete the surveys of the plains and mountains intervening between the werler1 boundary and the Pacific, heretofore partially &C., complished by the Exploring Sunadron and the two former expeditions of Capt. Fremont. As far as we can learn, this party will proceed to suIyey the Ar
 kansas river to it's source, after completing which the party will be divided. One division will then return by the way of the head of the Rio del Norie
 through lhe country of the Camanche Indians inc sources of Red River, and by the lowest waters bi the Arkansas. The main division udder CaplaIn Fiem mt will cross the Colorado, complete the sur vey Of the greaI Salt Lake. and penetrate by the waters of Mary's river, (which flows westwardly through Upper California, in he vicinIy Of the 42d degree parallel of aitude and is lost in lake al the eastern base of the California mountains IL is believed that from point on Mary's river, some days journey above Us mouth, the head of the Sa- crimento may be reached in two days trial. The SacrImento penerates Ihe main chain of ibe Cali iornIa mountains and lornsa practicable pass direct 10 the Bay of San Francisco. This alread, known. II IS also Known that practicable route exists from the head oi the Sacrlmento, m a norhery direction, by the heads of lhr kamet, Chuttes and WaIame,te rivers on the Columbia. The route then by which Chpt. Fremont proposes to penetrate 10 the Pacific IS the shortest and most direct from the lower Mis- soafi-of this, the portion from the head of the Ar Kansas to the head of the Sacrimento, about $50 miles in disance-is as vel unexplored by the whie man, and generally designated the great "Cali- iornia desert. None of its waters, excepting the Colorado, reach the ocean-thcy are absorbed or disappear bv evaporation. n
 Alter passing the winter among the American set. dement's of Upper California, the exploring party will. if the country he found practicable. pass round by the lower route from California, crossing the Co., lorado below the great "Kennion.'' and return 10 the Arkansas by the waters of the Ga and St. Juan large tributaries of the lower Colorado, which have their west of the mountains of New Mexico. This sketch contemplates route of five or six thou sand miles. It will probably evenluaie in the dis covery of new and ight road 10 both Oregon and California, passing for the most part thro' our own territory, diminishing the disian some three four hundred miles, and the time two months The country to the right and left will be examined, and it's geography ,iat present blank, somewhat un- derstood. The importance of these contemplated explorations is very great-eyery confidence IS re- posed in the energy and ability of the commanding officer. We shall hope for tbeir success, and look anxiousy for their safe return towards the close oi the year lS46.-Western (Mo.) Expositor.
