The machinations by which Greville served as literary executor and Ponsonby as unofficial stationer to the Sidney circle, for example, helped clarify what it meant for Sidney to have been a poet by envisioning him as an author whose heritable rights
were allied with, yet distinct from, the economic rights of his publisher.
In Britain, for example, there are private, heritable rights
to fish for salmon in rivers and streams.
Lord Sewell also pointed out that netting stations are private, heritable rights
which bring money in for their owners.
