The Son:-ttc of the Ullitecl States, anu thn Honse o{ Rep rrsrntati \'en having each Ol'd l'rCd tell tho nsand copies of tltf' reports of the lWO OX- • ploring expeditions COJl(1uctcd by me, to ue print 'd together, J hav deemed it regular and natural to place tlw r<'port of 1 ' 12 first in the onl r of pnblicatiou, although heretofore printed; it being first in the order of time, and first in the progress of actual e.·ploration. Tltc two reports 1Hltnrally go together, tile second being a continuation of the first, nnd tlw two constituting parts o( a wl101c, which will re<1uire a third cxpcuitiort, now commencing, to complete. The fir!it terminated at the Rocky moun tains, and at the two poin!s of greatest interest in tbn.t riuge-namely, the South Pass, and Fremont's Peak; the former being the lowest depression of the mountains, through which the road to Oregon now passes, and the larter the highest clcvatioll, from the base of which fonr great rivers take their rise, and flow in opposite directions, toward the rising and the setting !1\llll. The second, after approaching the Jtlonntains by a different rontr, connects with tlte first expedition at the South Pass, nnd thence finds tho great theatre of its labors west of the Rocky monutains, and between the Oregon river aml Nort lt California. Tho third expedition, now commencing, will be direct ed to that section of the l{or,lcy moun ttli ns wllic!t gives rise to the Arkansas, the Rio OrancJc del Nortr, and tile Rio Colorado of Cal ifornia; and will extend wrst and southwest of that sccti0n, so as to examine the country towards the Pacifi r, ocean, a5:ccrtain tho lines of commuuication between the nwnnt ains and the occ'an i11 that latitude, and cotnplete the examination of the Great Salt lake and of tlw intrrcsting n'gion which eu\bosorns it. t The map which illnstrateu the repo rt of 18 12 is now extcmlcu to illns-trate the entire expedition of 18,13-'44, so tltn.t a view of' both expeditions wjll be presentee]_ together. T his mrtp may h:-tve a meager ::tiH1 skeleton appearance to tltc general eye, but is expeete<l to be more valuable to science on that aecount, being wholly f'onnded npon positive data and ar.~ tual operations in the field.
