Quando aliquid conceditur, conceditur id sine quo illud fieri non possit

When anything is granted, that without which it cannot be effective is also granted. The grant of a dam overflowing the grantor's land at the time of the grant, following the maxim, carries with it to the grantee the right to continue the overflow. Troup v Hurlbut (NY) 10 Barb 354, 359.
