Whatever may have been the original limits of the .region which ancient discoverers and geographers named Texas, the boundaries of the revolted Mexican province of that name, are no more necessarily identical with those hmits, than are the boundaries of the State of Louisiana with the hmits once assigned to the vast territory bearing the same name. The State of Texas was carved by Mexico out of her domains, and, in union with Coahuila, was entitled to a common legislature, and a representation in the Mexican Congress. In 1833, Texas, as already mentioned, dissolved her union with Coahuila, but laid no claim whatever to any portion of the territory of her late associate. The limits of the State of Texas were well known, and defined on maps. Its boundary commenced at the mouth of the river Xueces, in Corpus Christi bay ; and followed that river to its source, thence to the hne of New Mexico, near the Gaudaloupe mountains, thence easterly to the southern branch of the Colorado, and along that branch to the main stream, and with that to and along the boundary hne of the United States to the Gulf of Mexico. The country between the Nueces and Rio Grande was embraced in Coahuila and the Northern dis- trict of Tamaulipas. A map of Texas, published in 1831, gives the Nueces as its southern hmit ; and in a description of Texas, published in the same year, by a visitant, it is said that the province is bounded by " the Nueces, T/hich divides it from Tamaulipas and Coahuila."
In 1833, Benjamin Lundy travelled extensively in Texas and Mexico ; and bis diary, published since his death,* con- tains entries which show most conclusively what was then considered by the Texans as the southern or south- western boundary:—"1833, October 11th. We pro- ceeded this morning over some delightful plains, on a good level road. At half-past nine, tve reached and crossed the river Nueces, which is the western limit of what is called Texas. Of course we are now in Coahuila "
