Be sure to use the link in the last post above.

In your sentence, I see these elements:

Clause 1 = Late in the evening Robert came late to dinner, riding on John's horse,

and

Clause 2 - we gave him ham and some boiled beans.

The phrase "riding on John's horse" is a participial phrase.
* riding = participle modifying "came"
* on John's horse = prepositional phrase modifying "riding"

Answer 2

I APPRECIATE THAT
