As for the careless storage of the powder; for [Don Juan says that] all there is on those islands is contained in a chamber of the fort of that city, and that in so prominent a place that it overlooks the wall; and that if by some accident (which may God avert!) this powder should explode, besides the risk to the city, there would remain no more powder in that whole country, nor material with which it could be made. To avoid so great a difficulty there would be built in some of the said four cavaliers two round towers, so that a large part of the powder could be divided and protected. Supposing that you realize how important it is that a part of the powder should be safe, and free from the accidents which might be brought about by any of it igniting, I charge you strictly to carry out this matter pertaining to the safety of the powder, that it may be more secure and suitably placed. He says that one of the motives which led him to fortify the wall is that the religious orders have built churches close to it, so large that they are obstacles; and because one of the churches, which is called Minondo, is near the Parián where during the year there are settled twenty or thirty thousand Sangleys (who are the people that rebelled in times past); and through mild measures the people of the Parián have aided this work with four thousand pesos from the treasury of their common fund. This has appeared well to us, and you will take measures in it which you may judge most expedient, warning them that no height commanding the city must remain. If there is any difficulty, and the churches would receive loss, you will avert such injury; and will send a plan [of the building]; and for the future you will not consent that any work be built to the damage of the public.
