King Coal by Upton Sinclair

They got to the place appointed without any fighting. And meantime Hal had worked out in his mind a plan for communicating with this polyglot horde. He knew that half the men could not understand a word of English, and that half the remainder understood very little. Obviously, if he was to make matters clear to them, they must be sorted out according to nationality, and a reliable interpreter found for each group.

The process of sorting proved a slow one, involving no end of shouting and good-natured jostling -- Polish here, Bohemian here, Greek here, Italian here! When this job had been done, and a man found from each nationality who understood enough English to translate to his fellows, Hal started in to make a speech. But before he had spoken many sentences, pandemonium broke loose. All the interpreters started interpreting at the same time -- and at the top of their lungs; it was like a parade with the bands close together! Hal was struck dumb; then he began to laugh, and the various audiences began to laugh; the orators stopped, perplexed -- then they too began to laugh. So wave after wave of merriment rolled over the throng; the mood of the assembly was changed all at once, from rage and determination to the wildest hilarity. Hal learned his first lesson in the handling of these hordes of childlike people, whose moods were quick, whose tempers were balanced upon a fine point.
