The question what covenants are " usual " is a question of fact.
A popular book, Jus Populi Vindicatum (1669), demanded the restoration of the covenants, which meant civil war, the hanging of the bishops, and even applauded assassination by men who had " a call," like Phinehas.
They maintained, however, their cherished covenants with a zeal which persecution only intensified; in 1680 the more extreme members of the party signed a document known as the "Sanquhar Declaration," and were afterwards called Cameronians from the name of their leader, Richard Cameron.
The component parts of a lease are the parties, the recitals (when necessary) setting out such matters as the title of the lessor; the demise or actual letting (the word " demise " is ordinarily used, but any term indicating an express intention to make a present letting is sufficient); the parcels in which the extent of the premises demised is stated; the habendum (which defines the commencement and the term of the lease), the reddendum or reservation of rent, and the covenants and conditions.
Thus a lessee is under an implied obligation to treat the premises demised in a tenant-like or " husband-like " manner, and again, where in a lease by deed the word " demise " is used, the lessor probably covenants impliedly for his own title and for the quiet enjoyment of the premises by the lessee.
