The government, with a view of obtaining full as well as reliable information on the hitherto hidden wealth of the country, appointed exploring commissions, and increased their number as far as the condition of the public treasury permitted it. Among the commissions a number were instructed to study the mining branch, two being sent to Michoacan, one to Guerrero, one to the states of Oajaca and Puebla, and one to the Huastecas. The special object of the last two was to survey and make a study of the carboniferous deposits. Some of the commissions rendered their reports between 1878 and 1882.[3]

- ↑ The commission in charge of Santiago Ramirez, intrusted with the exploration of Oajaca and Puebla, reported the results obtained in the districts of Matamoros, Acatlan, and Chiautla, in Puebla. It was also incidentally directed to explore the carboniferous deposits of the state of Tlascala, those of Tlaquiltenango in Morelos, Huetamo in Michoacan, Actopan in Vera Cruz, and to make a study of the coal of Tlaxiaco in Oajaca. The reports were published in the Anales de la Secretaría de Fomento. The two commissions despatched to Michoacan, besides procuring the discovery and examination of the coal-beds, were to study the metal deposits. Manuel Urquiza, the chief of one of them, made a report full of scientific and industrial data, which the governinent ordered published in the 7th vol. of the aforementioned Anales. Mex., Mem. Sec. Fomento, 1884, i. 451-637.
