I have said that the news of this dastardly attempt on Prince Ferdinand’s life caused the greatest excitement in Constantinople. There is indeed no doubt that both the Palace and the Porte are very seriously alarmed, as, in view of the Sultan’s disgraceful action in the Vulkovitch affair, it is only just they should be. It is significant of his Majesty’s state of mind that, when early this (Sunday) morning, first the French and then the Russian Ambassador drove to the residence of the Grand Vizier, they were unable to see him, orders having been sent from Yildiz ordering the Pasha not to receive them. Sir Clare Ford, on the other hand, had a long interview with the Sultan this morning. PHILIPPOPOLIS, _April 4_. When the train steamed into the station here, I learned in the restaurant, where every one was eagerly discussing the events of the past two days, that the second assassin was captured yesterday afternoon at Banja, as the result of an order widely circulated by both telegraph and horse messengers throughout the country, calling upon all Tchorbadjis, or headmen of villages, to detain any stranger found within their jurisdiction, and at once communicate with the nearest central authority. The man has been identified as one Nicholi Nāoum, a very well-known character who, besides being suspected of participation in the murder, last spring, of M. Beltcheff, is known to have been acting for the past six months as a revolutionary agent on the Macedonian frontier. Nāoum, who, as leader of a gang of border brigands, has gained a bloody notoriety in connection with various dastardly outrages against society, is believed to have been recently engaged in distributing arms and ammunition among Macedonian villages, and in inciting the Macedonians to molest the Bulgarians dwelling among them. Nāoum, when arrested, was found to be provided, like his accomplice, with a Russian passport executed in regular form. He was immediately carried back to Samakoff and confronted with Bendukdjieff, against whom he at once began to rail as a bungler, making no attempt to exonerate himself, or to deny his share in the tragedy. In this course, perhaps, he was guided by the knowledge that his life was already forfeited for many atrocious crimes before he set his hand against Prince Ferdinand. As a consequence of his last admission of guilt, a very brief trial was necessary, and the two wretches were hanged this morning outside the house in which they had lodged on Friday night in Samakoff.
