"The cause of a lawsuit between the owl and the kite" by Alice Elizabeth Dracott starts with the following sentence:
"The owl and the kite once went to law on these grounds."
I have problems with understanding "on these grounds". Since this is the very first sentence of the story, I understand it means something like "The owl and the kite once went to law on the following grounds", the grounds meaning more or less foundation/basis. Is my way of thinking at least close to what it should be?
