… Violet Blair Janin, a niece of Montgomery Blair, who was Lincoln's Postmaster General and an extensive landholder in Maryland, devised land to the Commission for use as a public park located at the boundary between Washington and Montgomery County. Illustrative of some of the conditions which a devisee may impose on his gift, Violet Blair Janin provided in her will that (1) the park be established in memory of and named after her brother, Jesup Blair, (2) provision be made to perpetually maintain the property as a public park, and (3) all existing trees be preserved if possible with the request that any which are destroyed or die be replaced. These provisions are restated in the laws and regulations of the Commission, and the Comimission is authorized to carry out the directions of the will. No court battle has been necessary to establish the sanctity of the park even though the State Highway Department has on occasion expressed an interest in taking some of the park for a road.
