No seal shall be required to any instrument conveying lands, tenements or hereditaments; and any instrument purporting to convey lands, tenements or hereditaments may be referred to as, and shall be, a deed, though no seal be affixed thereto; and the word "covenant" used in any deed or instrument to which no seal is affixed, shall have the same effect as though a seal had been affixed thereto.
