As we might expect from what has been said, the social life of the Philippines, at least from about 1875, may best be studied in the periodicals of Manila. In this connection it is only necessary to mention Retana's El periodismo filipino, which covers the subject down to 1894. La Revista de Filipinas, edited by J. F. del Pan, 1875-77, deserves special mention among the many periodicals of short life. Among those of longer duration may be named El Diario de Manila, and also, for the closing years of Spanish rule, La Oceanía Española, La Voz Española and El Comercio. [65] One should also consult these Spanish periodicals of Manila for the political history of these years, particularly of 1896-98. It must be remarked, however, that, just as these periodicals reflected mainly the life only of the capital, and that quite exclusively from the Spanish viewpoint, so also they treated political and administrative matters not merely under the constraint of their editors' notions as to "maintaining Spanish prestige" but also with a censorship in the background, maintained by and for the political and the ecclesiastical authorities. [66] Down to 1898 the Philippine law of censorship of 1857, modeled on that of Spain in the days of Isabel II, was in force, and it covered the publication of books and pamphlets of all sorts and of newspapers, the importation and sale of books, pictures, etc., and the regulation of theaters. [67] One will, therefore, look almost in vain in these periodicals prior to 1898 for expressions of the Filipino point of view, or, till the close of 1897, for any frank expression of liberal political views on the part of Spanish editors. The few Manila periodicals started by Filipinos before 1898, usually printed in Spanish and Tagálog, had but an ephemeral existence. [68] One must look for the expression of Filipino aims and ideas to the periodicals that have been published since 1898; indeed, even the Spanish press of Manila has treated Filipino questions with freedom only since American occupation began. For population statistics, all practical purposes are served by the tables and comparisons of the American census of 1903. [69] Here one may find also the best data for reconstructing before his eyes the social and economic status of the Philippines and its inhabitants at the close of Spanish rule. The Spanish civil census of 1896 was unfortunately never published, nor completed in some provinces. The civil census of 1887, though published in very condensed form, merits attention. [70] Certain of the more notable statistical works of private individuals will require notice in connection with agriculture, industry, and commerce; here the student may be referred to the Bibliography under the names of Agustín de la Cavada, J. F. del Pan, and José Jimeno Agius. [71] ECONOMIC DEVELOPMENT
