To the 16th, 17th& 18th Posta. Country of one uniform appearance: rich green plain, abundance of cattle horses & sheep; here & there the solitary Estancia, with its Ombu tree. — In the evening torrents of rain, arrived after dark at the Posta; was told that if I travelled by the Post I might sleep there; if not I must pass on, for there were so many robbers about, he could trust nobody. — Upon reading my passport, & finding that I was a Naturalista, his respect & civility were as strong as his suspicions had been before. — What a Naturalista is, neither he or his countrymen had any idea; but I am not sure that my title loses any of its value from this cause.
