"As I left the custom-house brooding over these perplexities, one of the principal clerks of the establishment slipped a piece of paper into my hand containing the following laconic notice:—"Aguárdeme afuera" (wait for me without);—an injunction I passively obeyed, although I had not the least idea of its purport. The clerk was soon with me, and remarked, "You are a stranger in the city, and ignorant of our severe revenue laws: meet me in an hour from this at my lodgings, and we will devise some remedy for your difficulties." ...I met the obliging officer in his room with a handful of blank custom-house pases. It should be understood that a pase only differs from a guia in requiring no endorser, but the former can only be extended for amounts of goods not exceeding fifty dollars. Taking my bill, he very soon filled me up a pase for every package, directing each to a different point in the North. "Now," observed my amiable friend, "if you are disposed to do a little smuggling, these will secure your safety, if you avoid the principal cities, till you reach the borders of Chihuahua: if not, you may have a friend on the way who will endorse your guia." I preferred the latter alternative. I had formed an acquaintance with a worthy German merchant in Durango, who, I felt convinced, would generously lend his signature to the required document."
