It appears that some months ago a deputation of Philippine natives went to Japan and presented a petition to the Mikado, praying his Majesty to annex these Islands. The petition was signed, it is said, by 5,000 natives and half-breeds. The Japanese Government, far from regarding the troubled condition of Spanish affairs as their opportunity, forwarded the petition to the Spanish Government, thus the names of 5,000 disaffected persons became known to the authorities here and were inscribed in their Black Book. No measures, however, were taken until the storm was about to burst. Intense excitement prevailed amongst the Europeans as the names of the 300 arrested were disclosed, for they were not mostly individuals known to us personally or by repute. But since then three months have lingered on, with the daily arrests of so many men of position that we are prepared to meet the most startling event with perfect equanimity. On the 23rd of August the leading newspaper of Manila published a stirring article, ringing with high patriotism, which concluded with an appeal to the Spaniards to go en masse to Government House the next day to discuss a proposal for extraordinary measures. They closed their offices and shops and went. It looked like a Sunday or a three-cross saint day. The Governor-General refused to receive them, and fined the newspaper $500, which was raised at once by public subscription. Indignation was openly expressed. A cablegram was sent to the Home Government asking for one thousand troops, etc. The reply came advising the immediate dispatch of 2,000 men, two millions of cartridges, 6,000 Remington rifles, and the gunboats Isla de Luzon and Isla de Cuba. Every fortnight, indeed, has brought fresh supplies of troops, which now make a total in the colony of about 10,000 Spanish regulars under arms.
