The volume contains a 54-page manuscript copy of Manuel de Mier y Terán's Spanish-language report on native people of Texas, entitled Noticia de las tribus de salvages conocidos que habitan en el departamento de Tejas, y del número de familias de que consta cada Tribu, puntos en que habitan y terrenos en que acampan , which he submitted to the Mexican government in 1828. Terán's assistant and draftsman, José María Sánchez y Tapia, produced the undated copy from Terán's manuscript. Terán's report provides quantitative and qualitative information on 29 tribes residing in Texas, including the Lipanes, Comanches, Huecos (Wacos), Tahuácanos, Cherokees, Kicapoos (Kickapoos), Iguanés, and Cadós (Caddos). He provided an approximate number of families in each tribe, detailed information on their locations, and sometimes commented on their habits and ways of life. On the Comanches, he noted that upon the death of a comrade, they killed the horse and broke the weapons which had served the deceased (pp. 6-7). For the Huecos (Wacos), he described the division of labor between men and women (p. 12). In addition to numbers and locations of various groups of Native Americans, Sánchez recorded several eight-measure songs, including lyrics, associated with the Táncahues, Tejas, Nadacos, and Iguanes tribes. In the back of the volume are an unfinished watercolor landscape and the lyrics to a song entitled "La Ausencia."
