"Without losing a moment," writes P. Mariano Gil, to a friend who had asked of him the true story of what took place on that memorable occasion, "I sent notice to the Lieut. of the Veterana of this sub-division, D. José Cortés, to whom in the presence of the denouncer, Patiño, I communicated the most necessary data, giving him at the same time the names of all those persons in the printing establishment who were compromised, commencing with the two who signed the receipts, Policarpo Tarla and Braulio Rivera, indicating to him the manner of procedure for the detention of all those complicated. ................................................................... ... "I decided, confiding in God, to go alone to the printing establishment, at a time when none of the workmen should be present." The writer goes on to explain how he made known his mission to D. Ramón Montes and two other Spaniards who, astonished at the news, aided in the search for the documents, stones etc. After a half hour's search the lithographic stone was discovered, and like a tiger springing upon its prey, the zealous son of St. Augustine pounced upon it, as though he feared that the very roof of the building should fall in upon it and bury it beneath its rubbish out of reach of his hands. A proof was taken from the said stone, of the Katipunero receipts, and P. Gil immediately set off in the direction of the Veterana of Tondo where he met Patiño, who recognized the receipt as authentic, and two hours later the Patriotic Augustinian saw his efforts crowned with the confession of guilt of the delinquents, the two previously named, figuring at the head of the list. Having performed this, P. Gil humbly wended his way back to his parochial dwelling, satisfied to have been an instrument of divine Providence for the unravelling of one of the most bloodthirsty plots ever invented by the perverse mind of embruted mankind. At midnight was discovered in the locker of Policarpo Tarla, in the same place, a dagger, the regulations of the Katipunan and several documents having connection with the said society, all of which, together with the famous lithographic stone, were handed over by Sr. Montes to the Veterana. On the following day P. Gil discovered in the house of one of his parishioners a dagger identical to the one mentioned, also several receipts in Tagalog with the key of the symbolic language in which they were printed. "This", affirms P. Gil, "is the truth of the discovery."
