Brown owned Blackacre, a tract of undeveloped land. Blackacre abuts Whiteacre, a tract of land owned by Agency, the state's governmental energy agency. At Whiteacre, Agency has operated a waste-to-electricity recycling facility for 12 years. Blackacre and Whiteacre are in a remote area and Whiteacre is the only developed parcel of real estate within a ten-mile radius. The boundary line between Blackacre and Whiteacre had never been surveyed or marked on the face of the earth. During the past 12 years, some of the trucks bringing waste to the Agency facility have dumped their loads so that the piles of waste extend from Whiteacre onto a portion of Blackacre. However, prior to the four-week period during each calendar year when the Agency facility is closed for inspection and repairs, the waste piles are reduced to minimal levels so that during each of the four-week closures no waste was, in fact, piled on Blackacre. Neither Brown nor any representative of Agency knew the facts about the relation of the boundary line to the waste piles. The time for acquiring title by adverse possession in the jurisdiction is ten years. Last year, Brown died, and his son, Silas, succeeded him as the owner of Blackacre. Silas became aware of the facts, demanded that Agency stop using Blackacre for the piling of waste, and, when Agency refused his demand, brought an appropriate action to enjoin any such use of Blackacre in the future. If Agency prevails in that action, it will be because 
the facts constitute adverse possession and title to the portion of Blackacre concerned has vested in Agency. Brown's failure to keep himself informed as to Agency's use of Blackacre and his failure to object constituted implied consent to the continuation of that use. consent to the continuation of that use. the interest of the public in the conversion of waste to energy overrides any entitlement of Silas to equitable remedies. the power of eminent domain of the state makes the claim of Silas moot.
