Nos. 1. 2. 3 and X. Scale 10 miles to 1 inch. The second map 
is only on one sheet, by Capt. Marcy, entitled. Topographical 
Maps of the roadfrom Fort Smith, Arkansas to Santa Fe , .V. 
Jf., and from Dona Ana, X. M.to Fort Smith. 
These two maps, are the first made on the spots by scientific 
explorers, and are mosl important for the exact geography of 
the Tucumcari area. Lieut. Simpson's map being on a large 
scale, gives all the details, as -well executed as can he expected 
from an exploring part} 7 , under military march, escorting a 
large band of California emigrants. The Tucumcari area is 
given on map No. 3, and is repeated on Map No. 4 in order to 
show the ••continuation of details" as it is noticed by Lieut. 
Simpson. On both sheets, we see, as described by Capt. 
Marcy in his diary, the Camp No. 57. on the Tucumcari creek. 
situated between the Little Tucumcari hill and the Big 
Tucumcari hill. Both Simpson and Marcy in their diaries, 
say that when in Camp No. 57, they received a visit from a 
party of Conimanch.es Indians, among them several chiefs. 
They came, while Simpson was engaged, under the protection 
of an escort of dragoons, in exploring the hill north of the 
camp, which he calls neither Little, nor Big Tucumcari. but 
only Cerro Tucumcari. Capt. Marcy received the Indians, 
and during the friendly entertainment and calumet smokes, he 
learned from them, that the hill north of the camp was called 
Little Tucumcari, when the one south of the camp was called Big 
Tucumcari. Simpson after his return from the northern hill, 
was made acquainted by Marcy with this; and he took it on 
his memorandum book — not in his diary — and when at Santa 
F6, in constructing the map of the road, on the 28th of July 
following, he took care to separate the Cerro Tucumcari in two, 
as the Commanches Indians had indicated on the spot, locat- 
ing with care and exactness the Little and the Big Tucumcari. 
The map of Capt. Marcy, on account of the small scale, 
does not give many details, but locates however the two hills, 
giving only one name, badly spelled by the engraver, of ( 'erro
