Wasutneton, D. C., October 17, 1854. 
Sra: I have the honor to transmit herewith a report and maps of the survey of a route for the 
Pacific railroad, near the thirty-second parallel, from Red river to the Rio Grande. 
. My instructions required me to examine also the military features of the route; and in this 
fact, and the short time at my disposal, is to be found my apology for the voluminous character 
of the report. 
am, sir, respectfully, your obedient servant,
