Las Bocas was slowly stewing in its native filth when the Three sighted it again at noon next day.

In all the world nothing reflects its environment more faithfully than a Mexican town. Southward, the great cities of Mexico and Guadalajara testify with their stately cathedrals, ornate public buildings, theaters, parks, and plazas, the flowering patios of lovely and luxurious homes, first to the richness of the central Mexican plateau, secondly to the fact that in normal times all the wealth of the republic drains to them. Oppositely, the northern towns with their squalid adobe streets, overrun with a plague of dirty children, dogs, vultures, pigs; desiccated by fierce heat, drowned by torrential rains; these in their place and turn are eminently characteristic of the arid desert. Save that it was a little smaller, a little dirtier, perhaps a little richer in the variety of its stenches, Las Bocas might serve as the type of all Mexican frontier towns.

As the wind blew their way, the Three smelled it from afar. But usage breeds indifference even to evil odors. If not actually homesome, the fetor bespoke a possible drink.

A quarter mile before entering the town they crossed the arroyo that gave it drink. Its waters also furnished an open-air laundry for two brown girls who knelt by its edge, pounding their soiled linen on flat boulders. These days of rampant revolution, a good girl had needs be careful, and at sight of the Three, dusty, unkempt, bearded, and gaunt from tire and travel, gringos at that, the two leaped up and fled toward the town.

Grinning at their fright, Bull and Sliver would have ridden on, but Jake, who never missed a trick, reined in his beast and began to examine the laundry with the eye of a connoisseur. Though the remainder of her be clad in rags, the humblest peona will have her lace petticoat, and the dozen or so pieces that were already spread out to dry on the neighboring bushes were really very fine.

“D’you allow to turn lady’s maid?” Sliver spoke, as Jake bent to stuff the lingerie into his saddle-bags.

“Not till Rosa’s had the refusal of it. This orter keep her satisfied for at least a month.”

Grinning, the pair of rascals spurred their jaded beasts and overtook Bull as he entered a narrow gut of a street that followed the meanderings of the original cow-path to the jefe’s house, a plastered adobe, limewashed in purple and gold, that faced the inevitable military barracks across a sorry attempt at a plaza.

If the small traders and artisans who constituted the bulk of the population had been addicted to such flights of imagination, they might have pictured the jefatura’s yawning gates as a huge gullet through which, in normal times, their substance drained in taxes, fines, and imposts to Mexico City, the nation’s stomach, there to be consumed by a hungry tribe of official hookworms. Now, of course, it was being deflected into the private pocket of the dominant revolutionary chief. Lacking the imagination, they cursed beneath their breath and waited patiently till the next revolution should bring a new tyrant to avenge them on the present oppressor.

The latest incumbent was at lunch under the peppertree in the patio when the Three dismounted at the gates. Fat and sleek and brown, his generally gross appearance was accentuated by pouched beady eyes, waxed mustache, unhealthy, erupted skin. As he sat there, shoveling in frijoles and chile, even a peon’s slack imaginings could have easily established a resemblance—if not between him and a hookworm, at least, to some greedy parasite. The irritability, blind individualism, offensive conceit, treachery, too common to Mexicans, lay hidden under the usual veneer of Spanish courtesy. The embraces, backpattings, effusive greetings with which he welcomed the Three would have graced the reception of a favorite son.
