[62] _Code of Virginia, 1950_, Title 7.1, Sec. 7. This Commission dealt only with the boundary below Jones Point but chose _low water mark_ as the line. The pertinent words of the agreement (ratified by Virginia in 1878) are: "The low water mark on the Potomac to which Virginia has a right in the soil, is to be measured ... from low-water mark at one headland to low water at another, without following indentations, bays, creeks, inlets, or affluent rivers. Virginia is entitled not only to full dominion over the soil to low water mark on the south shore of the Potomac, but has a right to such use of the river...." Interpretation of this agreement took many years and it was 1930 before the line actually was surveyed and monumented. [63] _Code of Virginia, 1950_, Title 7.1, Sec. 7. Cf. also page 9 above. The Commission accumulated a large volume of testimony and exhibits and completed its report[64] in 1935. It found that the "fair and proper boundary is the low water mark on the Virginia shore running from headland to headland across creeks and inlets." It pointed out that inasmuch as the mark of 1791 could not be determined the low water mark should be accepted as of this day. It suggested that an exception be made at Roaches Run where the line should run 150 feet west of and parallel to the west line of the Mount Vernon Boulevard.

Several bills[65] were introduced into Congress to give effect to the decision of the Commission but none was enacted at this time. The completion of the Airport and the Pentagon Building gave urgency to the problem: conflicts of jurisdiction hampered law enforcement and complicated the question of tax collection. Moreover, Virginia was anxious to insure that the liquor control laws of the State and not those of the District of Columbia should be in effect at the National Airport. In 1942, the General Assembly had adopted an Act[66] covering the boundary question, on the assumption that the bill then pending in Congress would be passed. Disagreement over the details of the jurisdiction to be ceded and accepted by Virginia and the United States Government prevented passage of a Federal Act until 1945 when Public Law 208 was enacted by the 79th Congress. This was followed by an Act[67] of the Virginia General Assembly repealing the 1942 Act and ratifying the 1945 Federal Act.
