ebration, held in New York City in 1882.Its promoter was an Irish-American labor leader named Peter J. McGuire.A carpenter by trade, McGuire had worked since the age of eleven, and in 1882 was president of the United Brotherhood of Carpenters and Joiners (UBCJ).Approaching the City’s Central Labor Union that summer, he proposed a holiday that would applaud “the industrial spirit – the great vital force of every nation”.On September 5 his suggestion born fruit, as an estimated 10,000 workers, many of them ignoring their bosses’ warnings, left work to march from Union Square up Fifth Avenue to 42nd Street.The event gained national attention, and by 1893 thirty states had made Labor Day an annual holiday.

The quick adoption of the scheme may have indicated less about the state lawmakers’ respect for working people than about a fear of risking their anger.In the 1880s the United States was a land sharply divided between the immensely wealthy and the very poor.Henry George was accurate in describing the era as one of “progress and poverty.” In a society in which factory, owners rode in private Pullmans while ten-year-olds slaved in the mines, strong anti-capitalist feelings ran high.Demands for fundamental change were common throughout the labor press.With socialist demanding an end to “wage slavery” and anarchists singing the praises of the virtues dynamite, middle-of-the-roaders like Samuel Gompers and McGuire seemed attractively mild by comparison.One can imagine practical capitalists seeing Labor Day as a bargain: A one-day party certainly cost them less than paying their workers decent wages.

s, signals, and even music over wires from one place to another. However, the human voice 36 this way. Many inventors tried to find a way to send a voice over wires, and in 1876 some of their efforts were awarded with success.

Two American inventors, Alexander Graham Bell and Elisa Gray, succeeded at almost the same time. The United States Supreme Court finally had to decide which of the two was the first inventor of the telephone. The Court decided 37 Bell’s favor.

Born in Edinburgh, Scotland, Bell grew up in a family that was very interested in teaching people to speak. His grandfather had been an actor who left the theatre to teach elocution(演讲技巧); his father was a teacher 38 deaf-mutes learn how to speak.

However, probably none of the later inventions gave Bell the same feeling of success __39_ he had on the day when he spilled some acid from his batteries. It was after he had worked for months to find ways to send something more than metallic twangs(金属砰弦声)over the wires. Thinking Watson, __40__, was in the next room, Bell called, "Mr. Watson, come here. I want you." Watson was not in the next room. He was down in his laboratory, next to the receiver.
