    New York City in the 1860s was a mess: crowded, disgusting, filled with garbage. You see, way back in 1860, there were no subways, just cobblestone streets. That is, until Alfred Ely Beach had the idea for a fan-powered train that would travel underground. On February 26, 1870, after fifty-eight days of drilling and painting and plastering, Beach unveiled his masterpiece—and throngs of visitors took turns swooshing down the track.

    Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked.

    They were tiny men, dressed all in green. Nobody but Frances saw them, so her cousin Elsie painted paper fairies and took photographs of them "dancing" around Frances to make the grown-ups stop teasing. The girls promised each other they would never, ever tell that the photos weren’t real.
