[16] One of the very rare allusions to this mode of conducting commerce, as used among the Moros, which--although common enough in all parts of the world from very early times, and practiced by most peoples who have risen beyond the savage condition--seems to have been even to the present time undeveloped among the Moros, partly on account of their fierce natures and the feuds among them, partly because of their habits of piracy, plunder, and bloodshed. Of especial interest in this connection is the account published in the New York Outlook, December 23, 1905, of the "Moro Exchange" established at Zamboanga, Mindanao (July, 1904), by Captain John P. Finley, governor of Zamboanga district. Intended from the outset to replace slavery and piracy by honest labor, it has gradually gained the respect and coöperation of the Moro chiefs; and by taking advantage of their talent for trade is exerting a wide and strong influence in the development of industry and peaceful relations among them. This exchange even in its first year had a volume of business amounting to $128,000; and now its daily transactions run from 500 to 800 pesos, while in the Zamboanga district it has fourteen branches. [17] Spanish, al reir del alba, literally, "at the smile of the dawn." [18] Limbo (from Latin, limbus): in scholastic theology, a region bordering on hell, where souls were detained for a time; hence, applied to any place of restraint or confinement. [19] The lists of Augustinian friars in the Philippines record the names of some thirty members of that order who became insane or demented; and probably similar lists could be given by the other orders. Perez's Catálogo (Manila, 1901), and Gaspar Cano's Catálogo (Manila, 1864) present biographical information regarding all the members of the order who labored in the islands from 1565 down to their respective dates of publication; Pérez enumerates 2,467 for the term of 336 years from 1565 to 1901, and of these 1,992 belong to Cano's period, ending in 1864. Cano names thirty friars (two of them being lay brothers) who died in a demented condition; the first of these was Fray Francisco de Canga Rodriguez (1616), who was 55 years professed. Pérez mentions but twenty-seven of Cano's list, but adds four others for the years following Cano's record (1865-1901), a total of thirty-one names. Both these compilers record the facts of dementia among the friars in varied phrases; and Cano speaks (p. 20) of "the many things which there are in Filipinas to cause the loss of one's mind." Zúñiga, in his Estadismo, refers to the liability of the missionaries in the islands to suffer mental alienation from homesickness, solitude, and lack of congenial companions, especially in districts where the natives were of low intellectual calibre. When I was a student in Rome, Pope Pius IX had a college (the Pio Latino) opened for Spanish Americans (from Mexico and South America); this was about 1860.
