(land dispute between parties regarding whether appurtenant easement existed from language in deed of land conveyed in 1940s; question concerned effect of easement language from previous deed; district court held language of easement was too vague to be enforceable; evidence showed parties never made use of any easement so intent shows lack of easement granted at that time; on appeal, appellate court agreed under state law that every conveyance of real estate passes the entire estate unless expressly stated otherwise; trial court affirmed no appurtenant easement in dispute land exists).
