In the streets the picturesque Mexican life is a-doing. The ranchero--so tight of trouser that it looks as if his legs must have been melted and run in hot into those grey pantaloons, like bullets in a mould--silver-spurred, his huge Mother-Shipton-shaped felt hat embroidered and bound with silver laces, his feet hidden in the great leather pockets which serve as stirrups here, canters into the plaza on a white Arab. Round the corner comes the milkman on a mule, his four jars of milk bulking so large round his saddle that you wonder he can get on or off. The raucous shouts of the Indians as their waggons jolt and bump and rattle over the broken cobbles: the "_Mūla-mūla!_" of the Mexican as he urges on the mules which draw the yellow varnished tramcars down the rickety lines: the cracked treble note of the old woman who thrusts her roll of lottery tickets into your face with the eternal "_Por mañana_," and the loud insistent cry of the brown-faced, barefoot, rascally-handsome newsboys, mingle into one inharmonious chorus. On the shady seats of the plaza loll the ever-tired Mexican workmen, smoking cigarettes. Twelve strikes, and the troop of _rurales_ in grey uniforms, with carbines and heavy revolvers--the mounted police--ride out from their barracks to take their work of patrolling the town. The townspeople gather and look, and then they sleep again; while in their shirt-sleeves, cigar or cigarette between their lips, Mexican clerks balance ledgers in banks and merchants' offices behind lattice blinds, and a postmaster in white-drill trousers and coloured silk vest sells you postage stamps between puffs of smoke.
