How still and cool and fresh it was at our suburban station, when the train, speeding away with a sardonic yell over the misery of the passengers yet standing up in it, left us to walk across the quiet fields and pleasant lanes to Benicia Street, through groups of little idyllic Irish boys playing base-ball, with milch-goats here and there pastorally cropping the herbage! In this pleasant seclusion I let all Bunker Hill Day thunder by, with its cannons, and processions, and speeches, and patriotic musical uproar, hearing only through my open window the note of the birds singing in a leafy coliseum across the street, and making very fair music without an anvil among them. “Ah, signer!” said one of my doorstep acquaintance, who came next morning and played me Captain Jenks,--the new air he has had added to his instrument,--“never in my life, neither at Torino, nor at Milano, nor even at Genoa, never did I see such a crowd or hear such a noise, as at that Colosseo yesterday. The carriages, the horses, the feet! And the dust, O Dio mio! All those millions of people were as white as so many millers!” On the afternoon of the fourth day the city looked quite like the mill in which these millers had been grinding; and even those unpromisingly elegant streets of the Back Bay showed mansions powdered with dust enough for sentiment to strike root in, and so soften them with its tender green against the time when they shall be ruinous and sentiment shall swallow them up. The crowd had perceptibly diminished, but it was still great, and on the Common it was allured by a greater variety of recreations and bargains than I had yet seen there. There were, of course, all sorts of useful and instructive amusements,--at least a half-dozen telescopes, and as many galvanic batteries, with numerous patented inventions; and I fancied that most of the peddlers and charlatans addressed themselves to a utilitarian spirit supposed to exist in us. A man that sold whistles capable of reproducing exactly the notes of the mocking-bird and the guinea-pig set forth the durability of the invention. “Now, you see this whistle, gentlemen. It is rubber, all rubber; and rubber, you know, enters into the composition of a great many valuable articles. This whistle, then, is entirely of rubber,--no worthless or flimsy material that drops to pieces the moment you put it to your lips,”--as if it were not utterly desirable that it should. “Now, I'll give you the mocking-bird, gentlemen, and then I'll give you the guinea-pig, upon this pure _India_-rubber whistle.” And he did so with a great animation,--this young man with a perfectly intelligent and very handsome face. “Try your strength, and renovate your system!” cried the proprietor of a piston padded at one end and working into a cylinder when you struck it a blow with your fist; and the owners of lung-testing machines called upon you from every side to try their consumption
