When a person affixes his property to the land of another without an agreement permitting him to remove it, the thing affixed belongs to the owner of the land, unless he chooses to require or permit the former to remove it: Provided, that a tenant may remove from the demised premises at any time during the continuance of his term any thing affixed thereto for purpose of trade, manufacture, ornament or domestic use, if the removal can be effected without injury to the premises, unless the thing has, by the manner in which it is affixed, become an integral part of the premises.
