Can someone summarize this for me i just need like 2 or 3 sentences "To the sick the doctors wisely recommend a change of air and scenery. Thank Heaven, here is not all the world. The buckeye does not grow in New England, and the mockingbird is rarely heard here. The wild goose is more of a cosmopolite than we; he breaks his fast in Canada, takes a luncheon in the Ohio, and plumes himself for the night in a southern bayou. Even the bison, to some extent, keeps pace with the seasons cropping the pastures of the Colorado only till a greener and sweeter grass awaits him by the Yellowstone"
