PaciFIC RAILROAD SuRvEYS: These surveys authorized 
by Acts of Congress of 1849 to 1852 in most cases pro- 
duced a preliminary report in 8vo form for each of the 
principal lines. The Central Line on the Arkansas, by 
Captain Gunnison, came by his death to the charge of 
Lieutenant Beckwith. All of these reports were outfitted 
with barometers, purchased and tested by me, and with all 
other suitable instruments for determining altitudes, gra- 
dients, and climate of the line traversed by each party. All 
the altitudes were determined by me on the return of the 
several parties to Washington, and the final reports were 
published in thirteen volumes, 4to, from 1854 to 1858. 
All of the 8vo reports of these surveys, twelve in number, 
and the materials embodied in the 4to volumes, were 
necessary to the construction of the charts and the estab- 
lishment of the principal conditions of climate as em- 
bodied in my Climatology. A special catalogue of all 
the documents and volumes relating to these surveys has 
been prepared.
