On this day in 1819 the Adams-Onís Treaty was signed by Secretary of State John Quincy Adams for the United States and Luís de Onís for Spain. The treaty renounced the United States claim to Texas. It fixed the western boundary of the Louisiana Purchase as beginning at the mouth of the Sabine River and running along its south and west bank to the thirty-second parallel and thence directly north to the Río Roxo, or Red River, "then following the course of the Río Roxo westward to the degree of longitude 100 west from London and 23 from Washington; then, crossing the said Red River, and running thence, by a line due north, to the river Arkansas; thence, following the course of the southern bank of the Arkansas to its source, in latitude 42 north; and thence by that parallel of latitude to the South Sea. The whole being as laid down in Melish's map of the United States." Spain delayed ratification of the Adams-Onís Treaty until 1821. By that time Mexico had declared her independence of Spain and refused to recognize the treaty boundary line.
On this day in 1836, former Mexican soldier Nepomuceno Navarro cast his lot with the Texas revolutionaries by enlisting in Juan N. Seguín's company of Tejanos. The company served as rear guard for General Houston's army, and Navarro served with Seguín at the battle of San Jacinto. For his participation in the Texas Revolution he received donation and bounty land grants and a pension. He was a member of the Texas Veterans Association until his death, in San Antonio in 1877.
On this day in 1935, the Connally Hot Oil Act became law. The act came about as a result of the federal government's attempts to deal with the problem of "hot" oil--petroleum produced in violation of state and federal quotas and regulations. In the early 1930s the overproduction of oil, largely a result of the East Texas oil boom, was adversely affecting the oil market. Sponsored by Sen. Thomas Connally of Texas, the law enacted in 1935 was intended to protect foreign and interstate commerce against "contraband oil" and encourage the conservation of domestic crude-oil deposits. It prohibited the shipment of hot oil. Under the law the president had the power to prescribe regulations and require certificates of clearance for petroleum and petroleum products to be moved between states. The law also called for the establishment of boards to issue certificates. Boards could conduct hearings and investigations regarding the enforcement of the act, and the United States District Courts had exclusive jurisdiction regarding judicial matters and disputes over denied permits. Though the legislation was intended to expire on June 16, 1937, it was maintained afterwards as a permanent law.
