C'liuliiig Limit. Fremont, ^Ir. (lever, luid C'apt. Belligny. an otticer 
of the Frencli army wiio wished to see the Indian country, 
thirty-three horses and ten carts. The years 1S40 and 1841 were 
spent at Washini>ton. where >Ii-. XicoHet had rooms for his work 
in the Coast Survey Imildiniis on ("ajjitol hill, and lived, with Fre- 
mont, in Mr. llassler s own house near at hand. (ien. Fremont, 
in his ••^lemoirs, "" gives many pleasant reminiscences of his work 
here with Nicollet, iind of the associations which they hail with 
Nicollet's persontd friends in Baltimore, where Mr. Nicollet fre- 
(juently retired for rest and recuperation — for his health was now 
seriously impaired, and he was alile to make luit slow head- 
way with his report. The map itself, executed under his immedi- 
ate e3'e, as the astronomical computations were made determiniuii' 
the chief points in his itinerary, was chietly drawn l»y Fremont 
and Lieut. Scammon. l)oth of whom had l>een assigned to that 
work for the assistance of >Ir. Nicollet. 
Tiis oflieial sui)eriors were planning lai'ger things for Air. Nicol- 
let, while his moiv intimate friends saw with sadness the gradual 
hut persistent decadence of his health. His map was completed 
in LS41, and sulnnitted to Congress. The Senate ordercil itspuh- 
lication under the direction of the Toi)ograpliical Bureau. It was 
to he accompanied l)y a report embracing an account of the phys- 
ical geography of thecounti-y i'('})resented. together with the most 
prominent features in the ge<dogy and mineral resources of other 
sections in the western part of the Ignited States not embraced in 
the area of the map. .Mr. Nicollet gave, in 1S41. an account of 
his work, and of his plans, at the Philadelphia meeting of the 
Association of American (ieologists and Naturalists, dwelling 
particularly on llu' geological discoveries he had made. lie was 
now at work upon his report. lie had the collaborative assist- 
ance of Di'. liailan. T)r. Torrey (in Botany) and to some extent 
of Messrs. ("onrad and ^':llmxem of the New York (icological 
Survey, then reci'iitly instituted. IJnt he was greatly delayed by 
ill health. The moi'c extended explorations which were being 
l)l;innc'd foi' him lind to be t r:iiisfei'rcd to his principal ,iid. I i lent, l-'re- 
mont, who. t liougli tiien young, was amt)itious, and withal certainly 
Ix'tter ([ualitied physically, for carrying out the di>signs of the 
(lovernnient in wcstci'ii exploi'ation. Had Nicollet's health liceii 
e([ual to the task it is likely that the great interior of the North 
American continent west of the .Mississipi)i. would have l)een ex-
