Show [ 148] 44 peditions which I have conducted, and which enable me to know what parts of the country most require examination, one year more· of labor in the field would furnish me additional materials sufficient to c0mplete a map of these countries, with topographical and descripti e maps of their most valuable parts, and a general map of the whole from the Mississippi river to the Pacific ocean. Having been many years engaged 10 this geographical labor, and hav .. ing made so much progress in it, I should be much gratified with an opportunity to complete it in the public employ; and I respectfully submit the subject to the consideration of your honorable body. This geographical memoir, as stated in the beginning, is only a preliminary sketch in anticipation of a fuller publication, which the observations of the last expedition would justify, but not sufficient to give the full view of Oregon and California which the increasing importance of those countries demands. The publication of the results of this expedition, with or without further additions from another exploration, is respectfully submitted to your consideration. The results of the previous two expeditions were publish-: ed by order of the Senate, and disposed of according to its pleasure. No copy-right was taken; and whatever information the journals of the two expeditions contained, passed at once into general circulation. I would prefer a similar publication of the results of the last expedition; but being .no longer in the .public service, an arrangement for the preparatiOn and the superintendence of the publication would be necessary. All whieh is respectfully submitted: , WASHINGTON' June, 1848. J. CHARLES FREMONT. ' • , • 45 [ 148] ., • APPENDIX. I.
