Ronald is the owner of a small farm. For the past twenty years, Ronald's farm relied on water drawn from a lake located three miles away. Each day, Ronald would take a truck to the lake and fill-up a tank with water. He would then drive back to his farm and use the water for his crops. One day, Henry purchased land adjacent to this lake. Henry is also a farmer, and he intends to also draw water from the lake. As a result, there will not be enough water for Ronald's farm. To protect his farm, Ronald sues to limit the amount of water Henry can draw from the lake.

(a) For Ronald to succeed in his lawsuit, what must be true about Ronald's farm?

(b) For the past twenty years, Ronald filled the tank in his truck from the same wooden pier located on land currently owned by Henry. Is it possible for Ronald to argue that he has acquired a profit (or "profit--prendre") that gives him the right to draw water from the lake?
