It was a pleasant, sunny, joyful morning. The anniversary of the nation's independence having fallen on the Sabbath, the celebration was observed on Monday, and the streets resounded with the explosion of fire-crackers. Americans, Germans, Norwegians, Irish, people of all nationalities, were celebrating the birthday of their adopted country. Not only in Chicago, but throughout the cosmopolitan State of Wisconsin, as we sped over its fertile prairies and through its towns and villages during the day, there was a repetition of the scene. Settlers from New England and the Middle States were having Sabbath-School, temperance, or civic celebrations; Irish societies were marching in procession, bearing green banners emblazoned with the shamrock, thistle, and harp of Erin; Germans were drinking lager beer, singing songs, and smoking their meerschaums. All work was laid aside, and all hands--farmers with their wives and daughters, young men with their sweethearts, children in crowds--were observing in their various ways the return of the holiday. Our route was by way of La Crosse, which we reached late in the evening. We were to go up the Mississippi on a steamer that lay moored to the bank. Its cabin was aglow with lights. Entering it, we found a party of ladies and gentlemen formed for a quadrille. They were the officers of the boat and their friends from the town. A negro with a bass-viol, and two Germans with violins, were tuning their instruments and rosining their bows. We were met upon the threshold by a rosy-cheeked damsel, who gleefully exclaimed,-- "O, yeau have arrived at the right moment! We are having a right good time, and we only want one more gentleman to make it go real good. Yeau'll dance neaw, won't ye? I want a partner. O, ye will neaw. I know ye will, and ye'll call off the changes tew, won't ye? Neaw dew." Not having a "light fantastic toe" on either foot, we were forced to say no to this lively La Crosse maiden; besides, we were tired and covered with dust, and in sad plight for the ball-room. A member of Congress was next appealed to, then a grave and dignified Doctor of Divinity. A more ungallant party than ours never stood on a Western steamboat. Governor, judge, parson, members of Congress, all shook their heads and resisted the enthusiastic lady. In vain she urged them, and the poor girl, with downcast countenance, turned from the obdurate Yankees, and sailed in gloriously with a youth who fortunately entered the cabin at the moment. It was a rare sight to see, for they danced with a will. They made the steamer shake from stem to stern. The glass lamps tinkled in their brass settings, and the doors of staterooms rattled on their hinges, especially when the largest gentleman of the party came to a shuffle. He is the Daniel Lambert of the Mississippi,--immense and gigantic, and having great development round the equator.
