President Harrison to explore the South Pass "in aid 

 of and auxiliary to the Oregon emigration. ' ' Leaving St. 

 Louis, well equipped with scientific instruments and with 

 Kit Carson as guide, Fremont examined the South Pass 

 of the Eocky Mountains and ascended the highest peak 

 of the Wind Eiver Mountains, which is now called Fre- 

 mont's Peak. In the course of his journey he experienced 

 much hardship, being frequently attacked by Indians, but 

 made many contributions to our knowledge of the Eockies, 

 returning with a vast amount of useful observations and 

 many hundreds of specimens in botany and geology. 



In the summer of 1843 he conducted a second expedi- 

 tion from St. Louis up the valley of the Platte river and 

 through the South Pass, explored the Great Salt Lake, 

 making important discoveries in geography. From Fort 

 Vancouver he journeyed to the Sacramento river, suffer- 

 ing severely from hunger and cold. Eeturning through 

 the Great Basin and the South Pass, he finally reached 

 St. Louis again late in 1844. 



In the spring of 1845 Fremont set out on his third ex- 

 pedition to explore that section of the Eocky Mountains 

 which gives rise to the Arkansas, the Eio Grande del 

 Norte of the Gulf of Mexico, and the Eio Colorado of the 

 Gulf of California; to complete the examination of the 

 Great Salt Lake and its interesting region; and to ex- 

 tend the survey west and southwest to the Cascade and 

 Sierra Nevada Mountains. 



Fremont undertook a fourth expedition in 1848, at his 

 own expense, assisted by public spirited citizens of St. 

 Louis, to explore a route for a railway from St. Louis 

 to California. He left St. Louis October 9, 1848, pro- 

 ceeding by way of the Kansas river to the head-waters
