I think it's "diversion" in the (unusual) sense of "an enjoyable activity", and "field" in the sense of "an open outdoor area with grass or crops". Which is a kid of ... poetic? ... definition of a "sport" (e.g. football, a leisure activity you do on a grassy square).

I don't think that's an unusual sense of "diversion" 150 years ago. It's the main sense of the cognate in Spanish or French.
