If you're not from the area you most likely would refer to this first image as a "fountain" or possibly "water fountain". However, you are terribly incorrect in calling this anything but a "bubbler" or if you want to be gauche, bubblah. See the little bubbles of water coming from the bubbler?
Ask anyone in Boston where is the fountain and they will direct you to a water feature in the Boston Public Gardens, Common or maybe on the new Rose Kennedy Greenway. Below, I've included a picture my favorite fountain.
