Alexander Wood Renton, 1911 Encyclopædia Britannica (1911)
“ This form of tenancy, like tenancy from year to year, may be treated either by express contract or by implication, as where premises are occupied with the consent of the owner, but without any express or implied agreement as to the duration of the tenancy, or where a house is lent rent free by one person to another. A tenancy at will is determined by either party alienating his interest as soon as such alienation comes to the knowledge of the other. ”
