Texas, were dispatched to Mexico City by their governments. Meeting with Mexico's foreign secretary, they signed a "Diplomatic Act" in which Mexico offered to recognize an independent Texas with boundaries determined with French and British mediation. Texas President Anson Jones forwarded both offers to a specially elected convention meeting at Austin, and the American proposal was accepted with only one dissenting vote. The Mexican proposal was never put to a vote. Following the previous decree of President Jones, the proposal was then put to a vote throughout the republic. On October 13, 1845, a large majority of voters in the republic approved both the American offer and the proposed constitution that specifically endorsed slavery and emigrants bringing slaves to Texas. This constitution was later accepted by the U.S. Congress, making Texas a U.S. state on the same day annexation took effect, December 29, 1845 (therefore bypassing a territorial phase). One of the motivations for annexation was the huge debts which the Republic of Texas government had incurred. As part of the Compromise of 1850, in return for $10,000,000 in Federal bonds, Texas dropped claims to territory that included parts of present-day Colorado, Kansas, Oklahoma, New Mexico, and Wyoming. The resolution did include two unique provisions: First, it said up to four additional states could be created from Texas' territory with the consent of the State of Texas and pursuant to the admissions process of the federal constitution. New states north of the Missouri Compromise Line would be free states, while those south of the line could opt to become slave states. Though the resolution did not make exceptions to the constitution, the U.S. Constitution does not require Congressional consent to the creation of new states to be ex post to applications, nor does the U.S. Constitution require applications to expire. Second, Texas did not have to surrender its public lands to the federal government. While Texas did cede all territory outside of its current area to the federal government in 1850, it did not cede any public lands within its current boundaries. Consequently, the lands in Texas that the federal government owns are those it subsequently purchased. This also means the state government controls oil reserves, which it later used to fund the state's public university system through the Permanent University Fund. In addition, the state's control over offshore oil reserves in Texas runs out to 3 nautical leagues (9
