450.     Proof of custom.

The custom of the country is the custom prevalent throughout the district, and is not proved by showing that it is the usage of a particular estate or of the property, however large, of a particular individual; and such usage will not be imported into the terms of a tenancy where it is not shown that the tenant was aware of it1. The custom is to be collected, not from what witnesses say they think the custom is, but from what they depose to having been done publicly throughout the district2.
