"See that, Cig?" he said, tapping me quickly on the shoulder. "That's pulky [pulque]. I mus' tell you 'bout that, too." The train started just then, and he waited until it was well under way. It was rolling along at a lively pace, and the brakes were rattling as they only can over a Mexican railroad. Barcas had to use the very top of his voice, but he chattered on, just the same. "Yes, Cig, that's the most important thing this side the line. Course the langwich's important, too, 'n' y'u got to learn it, but y'u mus' understan' pulky first. If I'd understood it when I was down here in '78, I'd never got into trouble, at all. Shorty 'n' Slim was with me, 'n' a lot o' other blokes that I don't rek'lect. But we was sixteen altogether. I'd never been here before, couldn't even say _adios_, so I thought I'd jus' look roun' a bit. An' for nigh on to a month we had a rip-snortin' time--drunk ev'ry day, 'n' so much to chew that I actually had to let my belt out a couple o' notches. An' we learned the langwich, too; by gosh! I could say ev'rythin' I wanted to. Course I didn't wanter say very much, I was so jagged, but I said enough, anyhow--see? "Well, this went on for pretty nigh a month, as I said, 'n' we was sloppin' up ev'ry day--but not on whisky. We went on the principle, do in Rome as the Dagoes does; so we drunk what them Indians was drinkin', pulky--mighty fine drink, too. Ain't had such dreams in a tenner as I had then. It jus' makes you feel 'appy all over, 'n' I use' to dream the whole twenty-four hours. Once I thought I was the pres'dent o' the New York Central--hope to die 'f I didn't. An' my pal he woke me up one night 'bout twelve o'clock 'n' told me that he was the Emp'rer o' the North Pole. An' the rest of 'em was jus' about as bad. We all thought we was kings 'n' queens 'n' royal flushes. Even tried to play poker with oursel's, 'n' I was the jack-pot for a while. "Well, one afternoon we was specially stuck on ourse's, 'n' went paradin' roun' the hang-out as if we was the high-monkey-monks of ev'rythin'. An' pretty soon a bloke called Curly soogested that we go over 'n' steal some more pulky at a Mexy's shanty clos't by. We was jus' drunk 'nough to do it, 'n' piled over there 'n' drunk ev'ry drop we could find. An' when we was through there wasn't en'thin' too good for us. We all thought we was royal families, an' a bloke called Red thought he was the chief of all. He was a big fella, 'n' that prob'ly swelled his head--see? Well, Red swaggered about for a while, 'n' then all of a sudden he swung his arms up Indian fashion, 'n says, 'Blokes, let's take the town.' He meant the city o' Mexico, the place we're goin' to see. Well, somehow or other it jus' struck us as a grand idee, 'n' we whooped 'n' hollered 'n' swore we'd foller 'im. Pretty soon we started. I was so jagged I could hardly keep on me pins, but that didn't matter; I was goin' to help take the city or break my neck.
