The Spanish language ought not to be taught them, but they ought to learn to read and write in their own. It is impossible to avoid the introduction of papers and books into the provinces which it is unadvisable for them to read, and experience demonstrates that those who know our language, are almost always the restless ones of the villages and those who murmur at, censure, and act contrary to the curas and alcaldes. [It is folly to teach the natives how to make artillery and firearms. Factories for the manufacture of these are now being finished in the islands. It would be better to send everything of this nature from Spain. Another imprudence is the manufacture of powder. Besides its inferiority to Spanish powder, and the danger of allowing the natives to learn to make it, it costs more than that sent from Spain. Although after the delivery of twelve thousand quintals, the factory and its effects are to become national property, the works which are now not worth more than ten thousand pesos, will be worthless.] [Mas recommends the use of steam vessels for inter-island communication, for the rapid moving of troops, and the better protection of Spanish interests. They can also be used against the Moros [20] with better effect than the small squadron of sailing vessels now employed, and will be more economical. Coal and wood abound in the islands and can be used as fuel.] The publication of a newspaper shall be permitted under the supervision of the government. In them shall be inserted descriptions of the best methods of making sugar, indigo, etc., dyeing thread, tempering iron, and in fact everything that may conduce to the instruction of agriculture and manufacture; the edicts and orders of the government; and political news, both peninsular and foreign, edited in the manner that is found advisable. [All the village ayuntamientos shall be compelled to subscribe to such a paper, and the cura shall be asked to translate into the native vernacular all useful articles. Foreign papers are admitted without any charge, and prove, instead of a benefit, an injury, for they are all democratic in tone, and foment disorder and discontent.] The non-existence of newspapers in Filipinas causes a very bad result among foreigners, who consider them and with reason, the foremost mark of civilization, and at the same time, the government is deprived of the advantage of guiding public opinion. [21] A system of police must be established, especially in the capital. Not many years ago, there was a commission of public vigilance, which was abolished, I believe, during the government of General Camba. The neglect of the captains-general in this regard at present is scarce credible.
