Página 13 - The material clearly is a mineral and it is reserved from the grant unless " the nature and context of the deed shows that it was not intended to be included " in the reservation. There is nothing to justify such a finding. The only claim that can be made is that the ledges of rock were so apparent and covered so large a portion of the original 100 acres that the parties could not have referred to them; that to except them would practically destroy the grant.
